Dear Sir or Madame,

In the ITU-T Recommendation H.225.0 I found about h245Address:

used in Alerting-UUIE, Call Proceeding-UUIE, Progress-UUIE, or Connect-UUIE: "This is a specific transport address on which the called endpoint or gatekeeper handling the call would like to establish H.245 signalling."

used in Setup-UUIE: "This is a specific transport address on which the calling endpoint or gatekeeper handling the call would like to establish the H.245 signalling. This should only be provided by the sender if it is capable of handling H.245 procedures before receiving a CONNECT on the Call Signalling channel."

My question is: I want to start H.245-Signaling after recept of Connect-message. Receiving the Connect-message, I get the transport address on which the called endpoint or gatekeeper handling the call would like to establish H.245 signalling. How can H.245-signaling run, if no h.245-address for calling endpoint or gatekeeper was defined before. I thought it has been done in Setup-UUIE. But what happens, if the sender of Setup-UUIE is not capable of handling H.245 procedures before receiving a CONNECT on the Call Signalling channel? Please can you help me to understand? I am looking specially for Gatekeeper-routet calls. Thank you very much.

Cincerely

Christian geng
