SIP-to-PRI Gateway Integration Solution

Seamlessly connect modern SIP trunks with legacy PRI-based PBX systems.

In today’s evolving communication landscape, enterprises are increasingly shifting towards SIP-based telephony for better flexibility, cost savings, and scalability. However, many organizations still rely on robust and reliable PRI-based PBX systems.

Our SIP to PRI Gateway Integration Solution bridges this technological gap—allowing you to adopt modern SIP trunk services without replacing your existing PBX infrastructure.

Solution Overview

The system architecture ensures smooth interoperability between SIP and PRI networks. SIP trunk services from the telecom provider enter the AKOM SIP–PRI Gateway, where SIP credentials are securely authenticated. The gateway then converts SIP signaling and media streams into standard PRI (E1) format.

This PRI output connects directly to your legacy PBX, delivering seamless calling functionality while maintaining operational continuity.

This integration lets businesses enjoy the advantages of VoIP technology while preserving investments in existing PBX hardware.
