What is a Microsoft Teams SIP Trunk?

A C2 Communications SIP Trunk will connect your business phone lines to your Microsoft tenancy. This will allow your users to take and make external phone calls directly from Teams. Implementing our unlimited SIP calling plans provides competitive pricing for all your business phone calls.

C2 Communications’ cloud-based infrastructure directly configures your numbers with Microsoft Teams. No hardware required. This allows you to have a modern PBX configured, with no additional costs of holding onto legacy devices.


How It Works?

With a Teams Phone System, your standard Teams functionality such as chat, conferencing, and internal calls are integrated with your company phone numbers.

We will assist you in enabling your Enterprise Office 365 Licenses to the necessary phone system users. With Teams Enterprise Voice enabled directly to each user, users can receive incoming, and make outgoing calls entirely through their computer, web-client, or mobile app.

A Microsoft Teams Phone System can be utilised with PBX functionality. This includes; call queueing, auto attendants, and group voicemails to suit your business’ needs.
