Hi, There is not direct one to one mapping between SIP and MGCP. You need to develop a generic call agent on top of SIP and MGCP agents. Based on the messages received on one side (for example INVITE on SIP side) generic call agent will decide what should be done on other side (for example selecting outgoing gateway and sending 'rqnt' to play ringing and notification for on hook. Send 180 ringing on SIP side.) When gateway goes off hook and sends NTFY, 200OK can be sent on SIP side. This intelligence should be kept in the generic call agent which will supervise both SIP and MGCP call agents.

How SIP messagens are translated to MGCP messages, in the Call Agent(in IMS context)?
