Hi All,
What is the first message exchanged between a gateway and Call Agent? Is it Notification Request command from CA to Gateway?

Is it mandatory that the first message will always be from CA to Gateway?

In Vovida's MGCP stack, how to send a MDCX message when the call is established.

Thanks in Advance
Regards
Surya Santosh

The gateway will send a RestartInProgress to the CA once it has finished
booting. The CA may of course be sending a message to the GW prior to
that happening, however there are certain in-order delivery requirements
aimed at ensuring the CA will learn about the GW booting before getting
a success answer back to any such commands.
