Secure, Reliable VoIP Phone Service

AltiGen’s SIP Trunk Service is powered by a geo-redundant architecture with three different points of presence (PoPs) to ensure uptime and service availability.  Our integrated solutions enable fast SIP Trunk service delivery, real-time DID number selection and rapid number porting.

Integrate Communications Across Locations

With AltiGen SIP Trunks your branch offices can maintain their local phone numbers, while enabling simple extension dialing between office locations – and eliminating toll charges for calls between your offices.  

Reduce Your Communications Costs

In addition to highly competitive rates, metro area and long distance calls are treated the same as a local call – so it’s no more expensive to call across the country (including Canada) than to call across town.  Our simplified, “no hidden charges” billing model enables you to easily stay on top of your communications costs.
