  • Is the issue number or name or both?  Number should be carried with the call.  Name requires a lookup.

    If you hook an analog phone to the line and call it, do you cet caller ID name and number?

    If you sniff a call off of the wire, what do you see for CID in the sip headers?

    How is cucm setup to do lookups?

    I know exaclt nothing about cucm, but I work for a clec.  Typically, CID issues should be troubleshot like anything else  - if more complex aspects of it aren't working, verify the simplest.

  • IT WAS CALLER-ID ISSUE But afterall i resolved it ,,it was not of sip headers it is h.323 gateway...thanks for ur reply

  • Care to share what the issue was and what the solution was?
