[h323plus] How to know about the remote sides H.239 capabilities?

Hi

Does anyone have any idea about how to know whether the remote side with which connection has been established supports H.239 or not. R Right now I try to open an extended session and check its return value. Is there any call in H323Plus which returns the H.239 capability status of remote side.Since we have already exchanged the capabilities, this information must be available somewhere.

Please help!!
