SIP Trunking Basics

SIP Trunks are virtual phone lines that use an IP-enabled PBX. Ideal for premises-based and distributed PBX’s, SIP Trunking allows businesses to make and receive calls virtually anywhere across the globe via the internet and through the PSTN. What’s more, calls can be made or received on a variety of phones or devices including traditional desk phones, computers or mobile devices, offering ultimate flexibility.

Delivered via a carrier-grade geographically resilient cloud infrastructure, our SIP Trunks are flexible and can be deployed over public internet, SD-WAN or MPLS connections.

Easy Deployment, Great Management Portal

Thanks to a self-service provisioning portal, SIP Trunking makes it easy to connect disparate locations and frees up IT staff to focus on strategic initiatives. What’s more, SIP Trunking helps bridge the gap between legacy infrastructure and emerging technologies, reducing reliance on PRIs and extending your existing PBX investment by delivering cloud-based connectivity.

With easy deployment in just minutes, capacity management and carrier-grade quality, SIP Trunking provides the worry-free connectivity service your business needs.
