Summary

Recommendation ITU-T J.178 describes the IPCablecom Call Management Server (CMS) to CMS Signalling protocol intended for use by a CMS to communicate with another CMS in order to support packet-based voice and other real-time multimedia applications. The protocol exchanges between a CMS and a Media Gateway Controller (MGC) are identical to those between CMSs, and so for purposes of this Recommendation the MGC is considered identical to a CMS.
