Cannot register MGCP gateway to CCM 4.1

Unanswered Question
Dec 11th, 2009


   I am running an application which simulates a MGCP gateway vs. a real CCM 4.1. I am not able to register the endpoints as you can see from the snapshot attached. I guess the problems lies in the 200 response to the following AUEP:

AUEP 89 [email protected] MGCP 0.1

200 89 OK
X: 2

L: p:20, a:PCMU, b:64, e:ON, s:ON

    I have also attached the trace file and CCM logs.


   I have 2 questions on this matter:

  1. what is the correct format of the 200 message which needs to be sent to AUEP with SRTP?
  2. how can I configure CCM not to sent this AUEP with SRTP(I have a similar one in my setup which is not sending this AUEP)?

Thanks in advanced for you support,


I have this problem too.
