SIP Trunking Phone Services

Flex-Voice SIP Trunking 

Our flexible Dial Tone service over IP connections is an excellent way to lower the cost of your voice communications or extend the life of your old PBX system.

Flex-Voice SIP Trunks are voice lines provided over Internet connections like Dobson Fiber, but also can work with other carrier's cable, DSL, T1's or other broadband connections. Why pay for separate circuits when you can get all your services over one broadband circuit?
