Support needed for MGCP using Asterisk

Hi,

We have Asterisk server, which we use it as both sip and mgcp server.

As per my understanding Asterisk will act as Call Agent and i see RSIP message coming from the Media gateway to Call Agent, but there is no response message 200 OK from the Call Agent to media gateway.

Could some expert help me to what changes that i need to do at my Asterisk side or at some mgcp.conf file.

Thanks
