Our global session initiation protocol (SIP) Trunking is a converged IP service based on a secure MPLS platform that delivers both voice and data traffic across a single network.

You’re managing big, complicated, expensive networks

Dealing with large amounts of voice and data traffic can mean lots of extra considerations for your tech teams — namely, disparate independent networks, each with their own flaws and complexities. It’s expensive and increasingly inefficient for the way we work today.

Data and voice, converged

T-Mobile Global SIP Trunking is a converged IP service that combines data and voice communication services into one solution. It offers a simple way to maximize network capacity, minimize the number of trunks needed, and save your business money. It’s front-ended with our Global MPLS service and delivers all telecommunication services over a single access circuit to the aggregated trunking location.
