CallManager Trace

Call Setup

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?

Comments

  • Add CUBE to the mix on R1 (same router as the GK), and use viazone to trigger the CUBE.
    Then run a 'debug h225 events' on R1 to find the reason for the call failure. Look toward the end of the debug in the billing section for the easiest to read answer as to why it failed.

  • Mark,

    Thanks your reply. I really appreciate

    I know the reason for call failure The remote GK has command "bandwidth remote 15" but I am trying to find out what debug on my local GK or trace in CM will show me this. Considering I don't have access to remote GK. Debug h225 asn1 and debug ras is not giving enough info.
