The VTech VSP736 ErisTerminal SIP Deskset is a mid-range SIP phone that can register up to six SIP accounts. With 32 programmable keys, dual Gigabit Ethernet ports, local call recording, and DECT 6.0 support, VTech seems to have stacked this phone with some impressive features, considering the price range. Does the phone deliver everything it advertises? We reviewed it to find out.
The VTech VSP736 has a large LCD screen with a resolution of 206 x 128 pixels and a white backlight. Although the phone is big, there’s not much to see in terms of functions like line appearances and busy lamp field (BLF). The design is similar to earlier models, including the VSP715 and VSP726, only this device is bigger.
The VTech VSP736 has four soft keys, 18 dedicated hard keys, and 32 dedicated programmable keys. Aside from the four soft keys, the phone also has a few dedicated function keys for call transfer, hold, conference, and contact directory.
A message waiting indicator can be found on the upper right corner of the phone. The screen also displays notifications such as missed calls or if a call was forwarded. A navigational pad, with its own separate select key, is available for navigating the menu.
The VTech VSP736 can register up to six SIP accounts. If you want to switch the SIP account you"re using, you have to press the “line” soft key. You can also assign the line function to one of the phone"s programmable keys.
You can access most of the features with the 32 programmable keys. We had to manually label the keys with the functions we assigned to them—otherwise, the keys can become confusing. The phone has only 16 physical programmable keys, so to access the other 16, you have to press the “lower” key found at the bottom right portion of the phone.
The VTech VSP736 features a PoE port and dual Gigabit Ethernet ports. The phone also supports DECT 6.0, so it can be paired up with wireless devices, such as the VSP601 handset and the VSP505/VH6102 headsets.
One of the more impressive features on this phone is local call recording. A micro SD card can be used for storage. Troubleshooting tools, such as pcap trace, syslog and logs, are available through the phone"s web interface.
The sound quality for the VTech VSP736 is decent to good. The phone supports the G.722 codec, providing HD voice quality. Our SIP-to-SIP calls were in full HD, but tests to other phones saw a minor drop in quality. The loudspeaker quality was average. Overall, the phone"s voice quality was quite similar to that of the VTech VSP715.
At OnSIP, we put each of the phones we use through a multi-step interoperability test in which we apply ~30 test cases. An example of a test case would be the following:
Call must be transferred correctly to C. B must be released correctly after the transfer. When C picks up, audio must work in both ways between test phone and C. When test phone is on hold, there is no audio between it and phone B.
The VTech VSP736 is a solid mid-range phone. The LCD screen could be improved to handle more navigation and features. As it stands, the screen currently makes it difficult to manage calls or implement features. Compared to previous versions, such as the VTech VSP715 and VSP726, the larger screen size didn’t add much value to the phone.
Most of the phone"s features are placed in the keys. One of the best features of the VTech VSP736 is local call recording. This makes it easy to record your calls without having to pay an outside service. The sound quality of the phone is average.
If you need to show someone what a phone looks like but want to avoid the risk of using real phones, a dummy phone is an excellent option. At an affordable price, dummy phones let you display a realistic-looking item that is not easy to break or desirable to steal. In addition to using dummy cell phones as a store display, you can use them in plenty of situations, ranging from a prop in a play to a toy for a child.Does weight matter when picking the phone?
As you browse through the broad range of display phones for sale on eBay, you"ll find that there are a few different options available for weights. Lightweight dummy cell phones may be empty inside the shell, so they are not as heavy as the real thing. If a product says it has an accurate weight, this means that it"s weight matches that of the real version.Can you use a dummy phone like a real one?
There are a few styles of dummy phones that work if you want the phone to look as realistic as possible. Some eBay sellers provide gently used products that still have a working display, even if they no longer have the capability of receiving cell phone service. You can also find some dummy phone styles with an LCD display that lights up and mimics basic functions like taking a photo or making a call.Which brands have dummy cell phones?
It is possible to find a dummy phone that mimics the look of a real model for most top cell phone brands. A few of the many brands sold by sellers on eBay include:Samsung
The shell of a dummy phone mimics the appearance of real dummy cell phones, but matching the look of a working phone is not always possible. There are a few different styles of dummy cell phone screens available, including:LCD: This style is an LCD screen that lights up like a real one, but it typically has a fixed image that you cannot interact with or change.
Single-handset phones are best for smaller homes where you’re never far from the phone. Otherwise you might be happier with a multiple-handset phone, which supports (and usually includes) multiple handsets from one base. Each extra handset sits in its own charging cradle, without the need of a phone jack, making it easier to station a phone where you want it. With some models, you can buy a replacement handset and charging cradle.
Most phones come with caller ID, a headset jack, a speakerphone, and ringer in both the base and handset. Check the phone’s packaging or download the instruction manual from the manufacturer’s website to confirm you’re getting the features you want. The more features a phone has, generally the higher its price.
Most cordless phones have very good overall voice quality. Some are excellent, approaching the voice quality of the top-rated corded phones. Most fully charged batteries provided 8 hours or more of continuous conversation before they needed recharging. Note: When the battery can no longer hold a charge, a replacement battery, usually proprietary, costs about $10 to $25. Some phones use less-expensive AA or AAA rechargeable batteries, which can be recycled.
More new phones have designs to enhance usability. That includes easier-to-read buttons and displays, visual "ringers" that signal an incoming call, talking caller ID, and volume boost, to name a few of the options.
Most cordless phones won’t work without electricity unless they have some kind of power backup system. Some have a compartment in the charging base for a spare handset battery pack or for alkaline batteries for base-power backup. Others use the stored power from the handset’s battery to operate.
Keep at least one corded phone with traditional landline service in your home, if only for emergencies. For most such models we’ve tested, the corded phone doesn’t require AC power to make and receive calls, although electronic features such as the illuminated display and built-in phone directory might not work. Keep in mind that any phone connected to VoIP services or fiber-optic networks won’t work if you lose electric power and don’t have a backup battery for the phone modem.

For Remote Access from a mobile device to the baby unit using the VTech app there must be an internet service available on both the mobile device and where the camera is located.
IMPORTANT NOTE: As your VTech RM HD model baby monitor is a WiFi enabled device they are driven by the WiFi signals in the house - when any dropout/congestion occurs that prevents the parent unit and baby unit communicating together it can take anywhere between 1 & 5 minutes for re-connection to occur in either Direct WiFi or Router mode (no different to how a pc/laptop/Smart TV needs to re-connect to WiFi when there"s an issue)
IMPORTANT NOTE: If you are experiencing connection problems when your baby monitor is operating in Router mode you should manually switch to Direct WiFi mode for internal monitoring between parent unit and baby unit. You can do this by turning off the parent unit WiFi connection via the Settings > Parent Unit Wi-Fi Connection option on the parent unit menu. This will not affect remote access between baby unit and the VTech app.
As these VTech monitors are Wi-Fi enabled devices, from time to time there may be issues created by factors that affect Wi-Fi connectivity within the home, that require this re-set process to get the device back to normal operation.
Up to date firmware is also critical to the operation of these models. To receive updates the monitor must be configured and connected to the Wi-Fi network (Router mode). To confirm what the latest firmware versions are go to; https://auphones.vtech.com/support/faqs/baby-monitors#153ab849-fea0-4e1f-a004-a2642cc98241
Step 6 – re-configure Wi-Fi connection (will allow firmware updates to come through to parent unit and cameras, will allow connection of cameras to MyVTech Baby app) via MENU > Settings > Configure Wi-Fi
2) the WiFi channel your VTech RM HD baby monitor is too congested to constantly stream High Definition (HD) video between the parent unit and baby unit.
Your VTech RM HD WiFi baby monitor uses available WiFi channels within your home network to constantly stream High Definition (HD) video between the parent unit and baby unit.
For HD video to stream constantly requires a relatively congestion free WiFi channel. If your parent unit displays a message stating to move your parent unit / baby unit closer together or closer to the router, it may be as a result of congestion on the WiFi channel your baby monitor is using.
NOTE: this should overcome most connectivity issues you may experience with your VTech RM HD baby monitor however should the WiFi channel again become congested this process may need to be repeated as required.
IMPORTANT NOTE: As your VTech RM HD model baby monitor is a WiFi enabled device they are driven by the WiFi signals in the house - when any dropout/congestion occurs that prevents the parent unit and baby unit communicating together it can take anywhere between 1 & 5 minutes for re-connection to occur in either Direct WiFi or Router mode (no different to how a pc/laptop/Smart TV needs to re-connect to WiFi when there"s an issue)
IMPORTANT NOTE: If you are experiencing connection problems when your baby monitor is operating in Router mode you should manually switch to Direct WiFi mode for internal monitoring between parent unit and baby unit. You can do this by turning off the parent unit WiFi connection via the Settings > Parent Unit Wi-Fi Connection option on the parent unit menu. This will not affect remote access between baby unit and the VTech app.
6) Test your RM unit using a password protected mobile phone hotspot. If the RM can locate the mobile hotspot, successfully connect to the hotspot and pair the camera, then the issue is with the WiFi network.
2) Once you have deleted the camera/s from the MyVTech Baby app you can change the WiFi network that your baby monitor connects to via the Settings > Configure Wi-Fi option on the parent unit menu
IMPORTANT NOTE: As your VTech RM model baby monitor is a WiFi enabled device they are driven by the WiFi signals in the house - when any dropout/congestion occurs that prevents the parent unit and baby unit communicating together it can take anywhere between 1 & 5 minutes for re-connection to occur in either Direct WiFi or Router mode (no different to how a pc/laptop/Smart TV needs to re-connect to WiFi when there"s an issue)
IMPORTANT NOTE (for models RM5754HD / RM5764HD / RM901HD / RM7754HD / RM7764HD only): If you are experiencing connection problems when your baby monitor is operating in Router mode you should manually switch to Direct WiFi mode for internal monitoring between parent unit and baby unit. You can do this by turning off the parent unit WiFi connection via the Settings > Parent Unit Wi-Fi Connection option on the parent unit menu. This will not affect remote access between baby unit and the VTech app.
1) Check through all items as per "My VTech WiFi enabled baby monitor can not locate my WiFi network?" above. Whilst the parent unit may have located the WiFi network one of these issues may be preventing the camera from transmitting a signal via your WiFi network.
3) re-pair the camera to the VTech app - you should now have video streaming from camera to both parent unit and VTech app. Test by accessing features of the camera from both the parent unit and the app such as zoom, lullabies etc.
2) To pair a VTech RM5752 / RM5762 model camera to your VTech app, you must have the mobile device your VTech app is located on connected to the same WiFi network as your VTech RM camera
3) Some WiFi networks operate on Dual Mode (have both 2.4GHz and 5GHz options available). Your VTech RM camera operates on the 2.4GHz option - your mobile device must also be connected to the 2.4GHz option in order to be able to locate the VTech RM camera.
4) Once you have confirmed that your mobile device WiFi connection is set up as above, if the VTech app is still unable to locate the VTech RM camera then reset the camera by;
VTech RM WiFi enabled monitors can be paired with either the main home WiFi device OR a WiFi range extender/repeater but not both i.e. unit will not hand over from one WiFi system to the other.
You can record video or take an image snapshot from within the MyVTech Baby HD app. As the video/snapshot from within the app saves to your smartphone/tablet memory, the maximum length of a video, or the number of images you can take, is determined by the amount of storage space available on the smartphone/tablet.
NOTE: The video recording feature of the app is not to be confused with the Motion Detection recording feature available on the RM5754HD/RM5764HD/RM7754HD/RM7764HD models. The Motion Detection recording feature, when turned on, will record a 10 second clip after motion is detected and save this to the onboard memory of the camera. These video clips can only be viewed/deleted via the Event section of the MyVTech Baby HD app. A maximum of 20 x 10 second clips can be stored onboard the camera.
After commencing playing lullabies, if the parent unit and baby unit link drops, even momentarily, you will not be able to turn the lullabies off using the parent unit. Simply go to the VTech app on your mobile device and turn the lullabies off from there.
3) The VTech RM cameras can only be viewed by a VTech app account to which they have been paired. To pair a VTech RM camera to the VTech app the user must have their mobile device connected to the same WiFi network the camera is using and must have access to the VTech RM parent unit to either retrieve the camera"s security code OR scan the QR code for connecting the camera to a mobile device.
VTech video baby monitors (excpet VTech RM & VM models which use a WiFi network to communicate) use a technology known as Frequency Hopping Spread Spectrum (FHSS). This technology is a highly secure, closed system that is incapable of being hacked by an external monitoring device as the frequently changing, random channel selection is known only to the sender and receiver (parent unit and baby unit of the baby monitor).
VTech video baby monitors are also only technically capable of having a single parent unit (video display unit) paired to a baby unit. Another user with the same model parent unit cannot, deliberately or accidentally, connect up to and view/hear another user’s baby unit that is not coded to belong to their parent unit.
VTech RM5752, RM5762 and VM9900 model range is dependent on WiFi signal strength in the operating environment as both parent unit and baby unit (camera) talk through the home WiFi network.
VTech RM5754HD, RM5764HD, RM7754HD and RM7764HD feature both Direct WiFi mode and Router mode. In Direct WiFi mode they have up to 100m range outdoors (clear line of sight between parent unit and baby unit) and 15m indoors. In Router mode range is dependent on WiFi signal strength in the operating environment as both parent unit and baby unit (camera) talk through the home WiFi network when operating in this mode.
Only those additonal cameras designed specifically for your VTech baby monitor can be paired to it. Cameras are not interchangeable between different models.
After approximately 10 minutes of inactivity the parent unit display will dim - this is perfectly normal. Pressing any key will return the parent unit display to the pre-set brightness level.
Check the Sound Activation/Sleep Timer/Auto Wake Up and/or LCD screen off timer settings on your VTech monitor. If switched to on and you do not want your screen to turn off automatically then change to off.
If set to on and you do want to continue to utilise the Sound Activation/Sleep Timer/Auto Wake Up setting then ensure the Sensitivity setting is set to a level appropriate to your baby / environment. The lower the Sensitivity setting the louder the noise required to activate the baby unit microphone for transmission to the parent unit.
Check the Sensitivity setting of your monitor and ensure this is set to a level appropriate to your baby / environment. The lower the Sensitivity setting the louder the noise required to activate the baby unit microphone for transmission to the parent unit.
NOTE: The Sensitivity setting affecting whether your parent unit detects and plays sound from your baby unit is model dependent i.e. not all models utilise the Sensitivity setting in normal operation mode. See "My VTech video monitor plays noise from baby unit even when Sensitivity setting set to low?"
The Sensitivity setting on some VTech baby monitors is only relevant to the Sound Activation/Sleep Timer/Auto Wake Up mode i.e. it does not affect the transmission of sound from baby unit to parent unit in normal operation mode.
Check the Sensitivity setting of your monitor and ensure this is set to a level appropriate to your baby / environment. The lower the Sensitivity setting the louder the noise required to activate the baby unit microphone for transmission to the parent unit.
To test that the Sensitivity setting is set at a level appropriate to your baby / environment you can test each sensitivity level by playing sound e.g. from your mobile phone or sound device, until you are satisfied that the selection is suitable for your situation.
NOTE: when playing lullabies/sounds on your baby unit, as these are detected by the baby unit microphone as noise, the Sound Activation/Sleep Timer/Auto Wake Up feature will not work i.e. the screen on parent unit will remain on.
When this feature has been turned on via the parent unit menu (or via the app), the Motion Detection of your VTech RM model baby monitor relies on 2 key factors;
3) For VTech RM WiFi enabled baby monitors also ensure the WiFi signal strength where the parent unit and baby unit/s is strong to ensure smooth video transmission.
In normal operation mode (not Sound Activation/Sleep Timer mode) the microphone on the baby unit and speaker on the parent unit are always on, ready for sound transmission. If the volume on the parent unit is set above approximately level 4 this may create a slight "buzz/hum" in the parent unit speaker. With normal day to day sounds occurring around the parent unit this should be unnoticeable however during quiet times it may become more noticeable. Simply turn the parent unit volume down during these times (this will not affect the sound transmission from the baby unit to parent unit).

Looking for a new cordless phone can be a little overwhelming. Which platform is right for you: DECT 6.0? 5.8 GHz? 2.4 GHz? Should you go digital or analog? The right phone can help you catch important calls, ensure privacy, and even manage a busy household. With the growing number of models that enable you to add accessory handsets to your existing base station using only one phone jack, you can create a multi-handset phone system within your home. We"ve created a quick summary of the choices you will face and outlined five key features you may want to consider for clearer and easier communication.
Your cordless phone is actually a radio transmitter/receiver that operates across a designated radio frequency. The three dominant platforms are 2.4 GHz, 5.8 GHz and DECT 6.0. Each platform can affect the signal clarity and the range your phone can reach from its base station; however, the actual range and sound quality of your phone can also be affected by obstructions within your home and interference from other electronic devices. Here are some general guidelines for choosing one of the four platforms:
2.4 GHz phones are losing shelf space to 5.8 GHz and DECT 6.0 models. As with the more popular platforms, 2.4 GHz models can host a variety of features, such as integrated answering systems, caller ID, speakerphones and support for multiple handsets. One thing to keep in mind is that other electronic gadgets, including baby monitors, microwave ovens and wireless networking gear may create interference on your 2.4 GHz phone. If you use these items in your home, consider purchasing a 5.8 GHz or DECT 6.0 phone.
5.8 GHz phones offer great clarity and range. The biggest advantage to a 5.8 GHz phone is that its frequency band is less congested than the 2.4 GHz band, resulting in less interference. 5.8 GHz phones are plentiful in the marketplace today and competitively priced.
DECT 6.0 technology is the latest cordless platform, providing improved range without needing to boost the power. This platform has been set aside exclusively for cordless phone use, which means that DECT 6.0 models have superior sound quality and do not suffer from interference created by wireless networks. This reliable technology has been in use for a number of years in Europe and has proven to provide brilliant quality of voice and sound, high protection against eavesdropping and better range than 2.4 GHz and 5.8 GHz phone systems.
Besides transmitting your voice on a designated radio frequency, a cordless phone sends your voice in analog or digital format, depending on the model.
Analog technology has been around for decades. With an analog phone, your voice is converted to electronic pulses and then transmitted on your phone"s designated frequency between handset and base. Analog cordless phones tend to be the most affordable and available option. You will experience adequate range and good voice quality. Drawbacks include poor security (anyone with a radio scanner will be able to listen in) and the potential for static and interference when you move too far away from the base unit.
Digital technology converts your voice to a series of zeros and ones; otherwise known as binary code, the language of computers. The transmitted code is sent on your phone"s designated frequency between handset and base, then decoded back to the original signal that you and the other party understands.
Digital cordless phones provide a stronger, clearer signal with enhanced security. Digital transmissions are less prone to static and interference. Most digital phones have the ability to switch to alternate channels when interference is detected, thus providing enhanced clarity over analog models. In addition, digital phones demonstrate enhanced range over comparable analog models.
Digital Spread Spectrum technology is another form of digital data transmission. The primary difference between conventional analog or digital models and DSS is that spread spectrum phones continually change channels during your conversation, only staying on a channel for a fraction of a second. This keeps others from "locking on" and eavesdropping, as well as avoiding areas of interference.
Like DECT 6.0, a digital spread spectrum (DSS) cordless phone provides enhanced clarity and security. Since the voice transmission is first digitized and then distributed in binary code across several frequencies, it is almost impossible for others to eavesdrop on your conversations. Channel hopping increases clarity because it limits the effects of other environmental sources of interference. DSS also provides enhanced range, as these models are allowed to run at a higher power level, thus boosting the signal.
A multi-handset phone system consists of a single base unit and two or more handsets. The base unit acts as a standard phone, and is plugged into both an electrical outlet and a phone jack. The satellite handsets all work off the signal from the base, and only need their chargers to be plugged into an electrical outlet. Therefore, phones can be placed in rooms where there are no phone jacks, such as a garage, living room or spare bedroom.
In addition to providing flexibility as to where you can place phones in your home, multi-handset models have other convenient features such as the ability to transfer calls from one handset to another and the ability to use the handsets as an intercom system. For example, if you need to ask someone upstairs a question, there is no need to yell or walk all the way up. Simply pick up your phone and intercom the upstairs handset. Multi-handset models feature line-in-use indication that lets you know when someone is using the phone. No more accidental interruptions!
AT&T offers two types of multi-handset systems: expandable and multi-handset bundles. Expandable systems give you the ability to add accessory handsets. This flexibility allows you to design a phone system that meets your specific needs. Bundles include two or more handsets in one box, and usually cannot be expanded beyond what is included.
Imagine your cordless phone system working in sync with your BLUETOOTH® mobile phone. AT&T offers a multi-handset solution that lets you make and receive cellular calls from any system handset.
Many AT&T cordless telephones feature an integrated digital answering system, making it easy to avoid having one more gadget on your desk or kitchen counter. Digital answering systems record outgoing announcements and incoming messages on a microchip. Tapeless operation assures reliable performance, instant access to messages and the ability to selectively save and delete messages. Available features include remote access to retrieve messages when you"re away from home, plus the ability to leave voice memos for others in your home or office.
If you subscribe to Caller ID service from your phone company, compatible phones will display the name and number of incoming calls on the LCD screen. Phones that are also Call Waiting capable will show you the identity of a second incoming call. This convenient feature lets you decide if you want to answer a call and allows you to use the memory feature of Caller ID to return a call, even if the caller did not leave a message.
Handy for meetings, conference calling and long on-hold times, many AT&T base units and cordless handsets also function as a speakerphone. In addition, most multi-handset systems feature an intercom, allowing you to talk between handsets or between handset and base.
