Eastlink enables businesses to leverage Microsoft Teams® phone system functionality, to replace their aging PBX/Centrex based services.
Eastlink connects MS Teams® clients to the Public Switched Telephone Network (PSTN) over Session Initiation Protocol (SIP), allowing users to keep their telephone numbers, make/receive telephone calls. Further, Eastlink ensures any remaining phone use cases, not addressed by Microsoft Teams®, are addressed through our hosted voice services.
