Many companies have already made an investment in an expensive PBX system but want to utilize Voice over IP technology. California Telecom offers a Trunk Replacement solution which allows your business to run Voice over IP using your existing PBX or KTS equipment protecting your investment. Trunk replacement is also an ideal way to test VoIP technology and provides an easy migration path to a fully hosted PBX system.

California Telecom will install an Integrated Access Device (IAD) that will connect to your existing PBX equipment via PRI/T1 CAS interface or via analog Amphenol connection. The IAD will be connected to California Telecoms backbone network and will also connect to your local network serving as a router. This way California Telecom can provide both data and voice services to your business with one connection. If your PBX system supports SIP directly no IAD is necessary.

This configuration provides access to DIDs nationwide and allows consolidation of your data and voice services to lower your long distance bills and other related fees and taxes.
