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 - headphones, 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 supply 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 headphones.
Cordless phones are also know as DECT phones. DECT stands for Digital Enhanced Cordless Technology. The DECT technology allows the handset to connect wirelessly to a 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 office where it will be used. In the above table this is indicated both by the Room size and Microphone (reception) radius specifications. Larger rooms can be accommodated by external microphones worn by conference participants (bought separately) to extend reception radius. Hence, models that support external microphones offer more flexibility.
Mobile phone support allows a conference to be held using any mobile phone number, even when the regular phone or IP network is down, essentially providing a backup independent phone line.

* In addition to mobile phone support, the Konftel 300Wx offers wireless IP or analog connection option using DECT technology. A separate base station is required for the wireless connection.
Another useful feature of the phone is the ability to record conference calls to an SD card for later playback or reference.
