Hello I am debuging a problem related to challenged re-INVITE for SDP solicitation
When the phone puts the call on hold, it tries to play MOH. In order to do this, it sends a re-INVITE to sipXbridge which is relayed to the ITSP. The ITSP challenges the re-INVITE (with no SDP) . SipXbridge presents another re-INVITE with credentials to solicit the offer The Offer is sent back to the phone and the signaling looks OK. However, I find that MOH sometimes does not play. I am wondering if there is a problem here with timing I have attached the logs for the MOH "Hold" interaction with the ITSP where the phone interacts with the park server. In the attached merged.xml, note that there are two MOH offer solicaation interactions with the ITSP The re-INVITE starting on Frame 39 failed to play MOH whereas the hold re-INVITE starting on Frame 133 did successfully result in MOH being played. I noticed some park server logs that indicated that a dialog could not be found. I am attaching the warnings here. I am not sure if this is related to what I am observing. If you see anything of interest in the attached logs, please comment. Thanks Ranga -- M.
