Telebroad supports two corded phone brands and one cordless brand. The corded brands are Poly and Yealink. The cordless brand is Yealink. We also sell conference phones by Poly, Yealink, and Konftell.
We have presently stopped selling Cisco IP 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 adapter, replacement handset, and Wi-Fi/Bluetooth adapters.
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. You will, however, need to get a separate power adaptor with the listed voltage if your network infrastructure does not supports the technology.

Cordless SIP Phones
Cordless SIP phones (that work with a VoIP network) offer the convenience of being able to step away from your office desk. They are a good choice for people who prefer talking into a handset over using wireless headsets.
Cordless phones are also know as DECT phones. DECT stands for Digital Enhanced Cordless Technology. The DECT technology allows a wirless connection between the handset and base station. The base station provides the connectivity to the SIP network. The talk range between handsets and the base station can be doubled with a repeater. Repeaters can also circumvent thick walls and other obstructions to help with indoor reception issues.
A base station is not limited to one cordless phone. It can handle multiple accounts and handsets (extra handsets need to be bought separately). Each handset can, in turn, handle several calls simultaneously.
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.

Conference Phones
Selection of 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 (reception) radius specifications. Larger rooms can be accommodated by attaching external microphones to the phone (bought separately) to extend reception radius.
