Integrated SIP Trunking in Microsoft Teams
Enabling VoIP calling in your Microsoft phone system requires a Calling Plan or a SIP trunk integration. In MS Teams, SIP trunking is known as Direct Routing. Microsoft Calling Plans provide "good enough" voice service in some regions, while Direct Routing unlocks exceptional phone number coverage and SIP call quality worldwide.
Why Do Companies Prefer SIP Trunks in MS Teams?
Common reasons cited by companies choosing SIP trunking over Calling Plans include:
- Global Numbers: AVOXI provides over 100 international number types not offered in Calling Plans.
- Call Quality: AVOXI's network sets the benchmark for global call quality and SIP network security.
- Superior Support: AVOXI's 99.995% uptime is backed by 24/7/365 phone support and dedicated account management.
