Frequently Asked Questions

  • TeamsPhone works with pretty much any PBX that is SIP compliant, in other words any phone system that works with VoIP phones such as Yealink, Polycom, Grandstream etc. It will NOT work with digital (not to confuse with VoIP) or analog phone systems, for example some legacy Nortel phone systems. If you are not sure if your PBX supports VoIP phones, please consult the manufacturer documentation.

    You can use both On-Premise (you have a physical box that’s your phone system) and Hosted PBX systems with TeamsPhone. A Hosted PBX is a cloud-based, virtual PBX phone system that provides phone service over the Internet instead of a self-managed appliance or server located at your premises.
