Mark Snow's Blog on MGCP Troubleshooting

Hi Mark,


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.
