Looks like it is not possible to turn off the automatic 100 Trying to INVITE from nua. If your application is pure redirect server, perhaps nta is better choice. Please note, however, that if your database lookup takes too long time, nta can also send a 100 Trying automatically. > The second issue I am encountering is the with the 302 behavior.

Perhaps the To tag in 302 and ACK do not agree or there is something else fishy? A message trace made with environment variables TPORT_LOG=1 TPORT_DEBUG=5 NTA_DEBUG=7 NUA_DEBUG=7 would he help. -- Pekka.Pessi mail at nokia.com ------------------------------------------------------------------------------ This SF.net email is sponsored by: SourcForge Community SourceForge wants to tell your story. http://p.sf.net/sfu/sf-spreadtheword _______________________________________________ Sofia-sip-devel mailing list Sofia-sip-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/sofia-sip-devel
