Hi All, I'm stumpted to figure out, about sending a REFER... The scenario is this UAC -> INVITE - UAS UAS -> 100 -> UAC UAS -> 183 => UAC //session progress <<< can uas send a REFER here >>> UAS -> 200 => UAC <<< it might be too late, since media session might have started on UAC, after inflight ACK >>> The idea is to transfer a call before media session starts. Any help is appreciated. Any place to look at beside the rfcs. thanks -p -------------- next part -------------- An HTML attachment was scrubbed...
