How many minutes do you need?  

Rely on 1-VoIP's Carrier Grade SIP Trunking instead of T1 circuits to eliminate the local loop component and reduce per minute costs. Compare and save significant costs by combining unlimited channel SIP Trunking with an IP PBX or legacy CPE, making conventional communication systems with separate phone and data connections unnecessary. Unlimited channel SIP Trunking services provided by 1-VoIP deliver unlimited concurrent calls to many compatible PBX's such as Asterisk, 3CX, FreePBX, Trixbox, Elastix, Switchvox, PBX in a Flash and many others on a network designed and built with redundancy and reliability in mind. If you're a PBX vendor, be sure to consider 1-VoIP's Partner Program.
