Cloud phone systems are rapidly growing in the enterprise market and have changed the way we work and communicate. Cloud Phone Direct is our SIP Trunking offering that supports direct routing to Microsoft Teams, Cisco Webex Calling and Zoom Phone for your voice needs.
CISCO Webex Calling
Our SIP Trunking service can provide Cloud Connected PSTN (CCP) capabilities for Cisco Webex Calling clients. You can make inbound and outbound telephone calls using telephone numbers assigned by or ported to GTT.
We can deliver dedicated SIP trunks to Microsoft Teams services residing in Office 365. As a Tier 1 ISP, GTT peers directly with Microsoft, ensuring the lowest latency connectivity between our voice network and Microsoft Office 365.
With Zoom’s BYOC feature, you can use GTT SIP Trunking together with the Zoom Phone cloud. You can enjoy all of the benefits and features of Zoom Phone while benefiting from our global voice solution for outbound calling, as well as new and ported DIDs.
