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.
Corded SIP Phones
All Telebroad's recommended phones are POE compatible – meaning they are powered by the Ethernet cable that also provides the network connectivity. A separate power adapter, with the listed voltage, is only needed if your network does not support this technology.

Cordless SIP Phones
Cordless SIP phones (that work with a VoIP network) offer the convenience of being able to step away from your desk. They are a good choice for people who prefer talking into a handset over using wireless headsets.
Cordless phones are also known as DECT phones. DECT stands for Digital Enhanced Cordless Technology. The DECT technology allows wireless connection between the handset and a base station that provides the SIP connectivity.
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 station that additional base stations connect to. 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 workers.

*** 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 integration manager) configuration where ten W90DM units can support up to 600 base stations!
If you use the W59R with W60 or W70 base stations you can use the RT30 repeater for range extension.
Conference Phones
Selecting a conference telephone mostly depends on the size of the room where it will be used. In the following table this is indicated by the room size and microphone radius specifications. Larger rooms can be accommodated by external microphones (bought separately) to extend the reception range.
