Enterprise SIP-PRI-POTS


As enterprises move on from legacy voice communications systems like the public-switched telephone network (PSTN), Session Initiation Protocol (SIP) trunking, Primary Rate Interface (PRI) over SIP and Plain old Telephone Service (POTS) over SIP have emerged as popular methods of facilitating voice communications over the Internet. These new technologies offer enterprises many advantages over legacy systems, including reduced costs, scalable architecture and enhanced reliability.

Open Interfaces

We customize our solution to fit your needs whether that’s native SIP or you are in need of a PRI, Digital or Analog interface.

Collaboration Services

By using SIP, companies can use the full suite of unified communications options: including video conferencing, presence services and many others.

Fax and Modem Support

allows customers to use fax and modem services as they normally did for decades.


Business Continuity

If a primary link fails, almost any stable Internet Connection can be used to register a new SIP connection.

SIP Enablement

Connect to VoIP telephony systems and register SIP anywhere and continue receiving calls regardless of location.

Cost Efficiency

SIP Trunks only require a reliable IP network path.  Eliminate costly dedicated circuits.
