With the following scenario, is resip/dum doing anything wrong or could the processing be improved somehow:
UAC UAS (resip/DUM)
<INVITE/200/ACK> - call setup is fine.
reINVITE ->
100 Trying <- (provideOffer() is called via DUM at approx the same time)
reINVITE <-
--- UAC’s re-invite is processed by DUM ---
491 <-
491 ->
At this point the UAC ignores the 491 (possibly because it got a 100???) and then eventually tears down the call.
I would expect the UAC to kill it’s re-invite after getting the 491 and try the re-invite again according to 491 processing rules.
Any help would be appreciated.
Thanks,
