Consolidate national and international offices for simplicity, efficiency, and quality

Why pay a phone bill for every office? Why pay for employees to call employees? With Leap, you can centralize communications at a single on-site IP PBX and deliver enriched voice, video, and data communications across your entire branch network.

Based on Session Initiation Protocol (SIP), SIP Trunking is an application layer protocol used to set-up real-time communications over the Internet. A SIP Trunk establishes dependable telecom service from your on-site Public Branch eXchange (PBX) to anyone, whether they are in the same office, in an out-of-state office, or on a cell phone on the far side of the world. By establishing one SIP Trunk to a centralized IP PBX, Leap can route calls throughout your network efficiently and reliably.

How do we achieve 100% uptime?


Since 2004, the Leap network has proven its reliability and security.


We test our network constantly for potential faults, being sure to maintain full redundancy with a zero fault tolerance.


Our engineers eliminate any single points of failure by placing multiple 10G connections with multiple IP carriers, so no matter what happens, call quality is retained.
