SIP trunks can be connected to a IP PBX and can replace or supplement your excisting lines and offer the advantages of
* Easy and quick to provisionl lines.
* Low cost trunk rental and call costs. Internal calls are free of charge to anywhere.
* Disaster recovery backup solution
* Flexible numbering (out of area codes)
* Can be delivered direct to the desk over your LAN
