How Teams Calling Works

Direct Routing works by combining the Teams system to the PSTN using two key elements: a an Iristel hosted and Microsoft Certified Session Border Controller and Iristel SIP Trunks.

SIP Trunks

These are connections between a business phone system, the internet and the traditional phone network (PSTN).


Often described as a "firewall for VoIP", these are used at the borders between different networks to make sure data is transferred properly between them. They also provide a layer of security and protection from attacks and breaches.

Users can use their mobile devices, a headset with a laptop or PC, or Microsoft -certified IP Phones.
