While studying MGCP protocol messages from debugs my head was spinning like ‘what the c**p message are those!’, had an weird idea to generate the call and capture all MGCP packets and write down explanation of each of the terms. I am weak on the MGCP debugs packets from the beginning of starting voice, now I just wanted to nail it down and wished to learn whole conversations between MGCP GW and the Call Agents. Tough one for me I know but who doesn’t want to learn something new? Took the challenge and I think now it’s quite easy for me. 🙂
Before starting the derivation let’s write down the MGCP Packet verbs and code explanations:
200 The requested transaction was executed normally.
250 The connection was deleted.
