iTeraTEL's SIP Trunking Solutions.

Harness the power of your data network for your voice communications.
SIP (Session Initiation Protocol) Trunking plugs into your existing phone system, replacing your traditional voice service such as analog lines & PRI's.

Business SIP Trunking Solutions

Bridge the gap between legacy infrastructure and emerging technologies while reducing reliance on an expensive and inefficient option, PRIs, and helps preserve your investments in on-site PBX systems while routing voice calls over data networks.

Completely Eliminates Copper Lines and PRI's


Consolidate Overlapping Networks - Consolidate all operations and expenses on one IP-based network that manages all voice and data capabilities.


Elimination of PRIs - SIP trunking eliminates the need to purchase PRIs (Primary Rate Interfaces) or local PSTN gateways helping to lower telephony costs.


Increased Productivity - Allow employees in different locations to contact each other with ease. A seamless connection between multiple offices, remote workers and employees on the move can streamline communication.


Scalability - Unlike traditional POTS and PRI lines, SIP allows companies to pay for only the lines that they require so there’s no need to purchase surplus lines in preparation for temporary peak times.


Reliability – In the event of a system failure or local power outage, SIP trunking providers can automatically reroute services to other locations, cell phones or wherever you desire.
