Hi! If I specify an outbound proxy (acc_cfg) as strict router (no "lr" parameter), then I observer the following behavior: 1. pjsua send REGISTER to outbound proxy (RURI and ROUTE is swapped due to strict routing) --> correct 2. pjsua receives 401 3. pjsua resend the REGISTER with credentials, but it send it directly to the registrar (RURI and ROUTE are either "not swapped" or "swapped twice") --> Bug bug exists in pjsua client and pjsua-lib can be triggered with: ./pjsua-i686-pc-mingw32.exe --registrar=sip:nic.at43.at --id=sip:foobar at nic.at43.at --username=foobar --password=foobar --realm=nic.at43.at --proxy=sip:pernau.at --nameserver=10.10.0.1 attached is the ngrep trace regards klaus -------------- next part -------------- An embedded and charset-unspecified text was scrubbed...
