Well, I think the problem is with the way nua/nta handles 100rel responses (I assume 183 is indeed a 100rel response). You could get away with a case if the PBX did not require 100rel. > I dont know if this is a problem with all forked calls, but I think it > is interessting for the sofia-sip project - so I would be very pleased > if someone can give me some hints. The problem is with the 100rel calls only (or so I hope). --Pekka > Am Freitag, den 07.12.2007, 16:07 +0100 schrieb Bernhard Suttner: > > Can nobody help or give a hint? > > > > > > Am Mittwoch, den 05.12.2007, 09:54 +0100 schrieb Bernhard Suttner: > > > Hi, > > > > > > I have a problem with two different two tags.
