Astelon VoIP Trunk – MS Teams & Office integration

You already use Microsoft Teams and want to call landline and mobile networks with it too? Use your Microsoft Teams as a phone system: we connect MS Teams to our SIP trunk – and you get the functionality of a phone system directly in Teams, with your familiar company phone numbers.

And the integration does not end with telephony: embedded in your Microsoft 365 environment, you start calls directly from Outlook contacts, your presence status follows your calendar (in a meeting = busy), and voicemails arrive as messages in your inbox. Telephony, Teams and Office work together seamlessly.
