SIP & PRI Trunking

Trunk service allows you to maximize your phone capabilities over ETC’s fiber network. With our business trunking services you can add channels as your business grows.

SIP

SIP Trunking integrates with your premise-based SIP PBX. It’s a tailored, cost-effective voice solution with scalable features and end-user mobility options that increase productivity.

PRI

Medium to large businesses with more than 40 extensions may want to consider a PRI plan. ISDN offers a digital 2-way connection between your business ISDN compatible PBX system and the Public Switched Telephone Network (PSTN).

SIP
