SIP Telephones Buying Guides (Corded, Cordless, and Conference)

Telebroad offers Poly and Yealink corded SIP phones and Yealink cordless SIP phones. We also sell conference SIP phones by Poly and Yealink. 


We have presently stopped selling Cisco SIP telephones. Any information about Cisco telephones we provide is intended for informative purposes only. We still provide full support for Cisco telephones purchased from us.


We also offer a wide range of telephone accessories  headsets, mounting brackets, ATA adapters, replacement handsets, and Wi-Fi/Bluetooth adapters. 


  The name of each phone model in the following tables links to its relevant user guides. We also have user guides for older/discontinued models.


Corded SIP Phones


All Telebroad's recommended phones are PoE compatible meaning they are powered by the Ethernet cable that also provides network connectivity. A separate power supply, with the listed voltage, is needed if your network does not support this technology or if you connect over Wi-Fi without a network cable. You can also use a PoE injector/adaptor to power the phone.


Yealink


Yealink phones allow for multiple accounts to be registered on the same phone. Only one account can actually be active at any given time, but the multiple registrations allow users to easily switch between phone numbers/accounts instead of having to log out/log in to a different account every time they need to switch numbers.

Poly


VVX phones support a local 3-way audio conferencing, meaning two participants can join you in a conference. A network conference can possibly increase the number of participants.

Accessories


For telephone mounting choices click here.


For telephone headsets choices click here.


For replacement handsets for your existing telephones click here.

USB Wi-Fi adaptor:  The Yealink WF40 and Yealink WF50 Wi-Fi USB dongles can connect your Yealink SIP phone to an existing wireless network. The plug-and-play device is a convenient solution for offices with a Wi-Fi only network or for phones that are too far from an Ethernet port. Note that the WF40 model only supports the 2.4GHz frequency!


Bluetooth adaptor: The Yealink BT-41 dongle adds Bluetooth functionality to your Yealink SIP phone and enables it to connect to a wide variety of Bluetooth Headsets. 


ATA adaptor: Analog Telephone Adaptor is a device that connects traditional analog telephones and fax machines to a VoIP network. You may want to buy one if you have some standard telephony equipment that works well for what it does but you want to use it with your VoIP network. In other words, ATA allows you to avoid having to operate and maintain two networks – standard and VoIP. You can read more about it here

Cordless (DECT) SIP Phones


Cordless SIP phones offer the convenience of being able to step away from your desk. They are useful for users who prefer to use a handset over a wireless headset or who need a wider wireless reception range.  


Cordless phones are also known as DECT phones. DECT stands for Digital Enhanced Cordless Technology – a technology for a wireless connection between the handset and a base station. The base station provides the handset with connectivity to the SIP network and can handle multiple accounts and handsets. 


The talk range between handsets and the base station can be extended with a repeater or with a multi-cell configuration. The latter requires a DECT manager unit. Repeaters and additional base stations can also circumvent thick walls and other obstructions to help with indoor reception issues. 


When setting up cordless phones, in most cases you would want a separate phone number for each handset, but there is also an option to share numbers among several handsets/users.


The following phones are offered as a bundle (handset and a base station). If you are just interested in adding a handset to an existing/different base station you can just buy the listed handset separately.

Under ideal conditions

** The W80/W90 can be bought or configured as either a DECT manager or a base station. For range extension, the system needs to be set up in a multi-cell configuration with one W80DM or W90DM (DECT manager) supporting up to thirty W80B or sixty W90B base stations. The W90 can also be deployed in VIM (Virtual iIntegration Manager) configuration where ten W90DM units can support up to 600 base stations!

Conference Phones


Selecting a conference telephone largely depends on the size of the space where it will be used. In the following tables, this is indicated by the room size and number/reception radius of the phone's microphones. The microphones pickup angle (360° omnidirectional or 120° unidirectional) can also matter. However, larger spaces can be accommodated by external microphones (bought separately) that enhance the phone's reception range.

* The Yealink CP935W is a battery-powered DECT (wireless) phone that pairs with the Yealink W70B, W80, or W90B base stations for a wireless coverage of up to 165 feet indoors. The phone itself is cordless and does not support POE (the base station it connects to does support POE.) The battery provides up to 15-20 hours of talk time and 75-160 hours of standby time, depending on if Wi-Fi or DECT connectivity is used.
