Hello Attached is a trace depicting a successful blind transfer operation.
Frame 36 shows sipxbridge soliciting an offer from the iTSP The ITSP responds in Frame 38 The answer from the phone is relayed back in frame 63. Between frame 38 and frame 63 the phone on the calling party side ( i.e. ITSP) would be expected to ring but I cannot send a RINGING because I got an OK already from that side. Question: How do we circumvent this problem? It would be nice if the caller heard a comforting ring. Note that I cannot delay sending BYE on frame 75 until after the ACK which would allow the Park server to play music until pickup since this winds breaking when the target of the transfer is the park server. See the following thread for details on the situation above http://list.sipfoundry.org/archive/sipx-dev/msg13465.html So the only option I have is to send the BYE on frame 75, leaving the caller with a silence when the phone is ringing. How can this problem be resolved to at least allow MOH to play until pickup (or preferably RINGING at the caller phone while the transfer target is ringing if that were possible)? I think the answer lies in the park server being able to handle the case above but I would like to solicit an opinion here. Thank you in advance. Ranga -- M. Ranganathan
