PhoneA --- UCM --- Gatekeeper A ------ Remote GK --- CME --PhoneB
I am trying to make a call from phoneA to PhoneB call fails. When I run deb h225 asn1 and deb ras on GK A, I can see LRQ and LCF that mean remote GK is able route the call. UCM and CME are failed to negogiate the parameters.
What trace can I run on UCM to find out why this call failed?
