Microsoft Teams phone solutions let the enterprise Teams client reach PSTN and SIP trunks. In Direct Routing, a certified SBC (Session Border Controller) terminates sessions at the edge and connects the carrier trunk securely to Teams. Define corporate number plan, user licensing, and emergency calling registration at project start.
Nolto evaluates AudioCodes and compatible SBC families together with the SBC product catalog and integration services. Number porting and emergency address records should be clarified at project start.
