What is the relationship between MGCP and SIP?

The details of combining the two in a system are still being fleshed out. MGCP is a device control protocol, where a slave (gateway (MG)) is controlled by a master (media gateway controller (MGC), call agent). SIP may be used between controllers, in a peer-to-peer relationship. Note that to the SIP side, the MGC looks like a node with a large number of connections, but otherwise the same as a “native” SIP device. Similarly, the MG is completely unaware that the call between MGCs is established via SIP. Only the MGC needs to understand both protocols. Additional details.
