Mark Snow's Blog on MGCP Troubleshooting
I was reading your Blog Post on MGCP Troubleshooting.
When we call a remote endpoint , you mention that MDCX Message with M : sendrecv is sent by CUCM when call was answers by far-end-party.
But our testing shows , M: sendrecv (MDCX) is sent when remote-party starts ringing. ( because this message is sent simultaneously with ISDN alerting message)
Please explain this.
