Sorry, but H.225.0 section 7.11.1 (ARQ fields description) states:
srcInfo: [...] When sending the ARQ to answer a call, srcInfo
indicates the originator of the call.
Concerning case 2, this means that srcInfo is the address of EP2.
PS: I think this discussion would be better placed on the
h323implementors mailing list, don't you ?
