Secure, Reliable VoIP Phone Service

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.
