Hello everyone,
I am trying to add a gateway, but after configuring it just like the others gateways I have, it is failing to register with a message like this:
2009-09-29 12:54:40.853440 [ERR] sofia_reg.c:1402 orange Registration Failed with status Operation has no matching challenge [904]. failure #1
2009-09-29 12:54:40.906798 [WARNING] sofia_reg.c:364 orange Failed Registration, setting retry to 10 seconds.
I captured the sip traffic and noticed that when trying to register with one gateway (the one that works), I get a "Trying" reply immediately followed by a "401 Unauthorized" which contains a "WWW-Authenticate: digest" with a "qop=auth" parameter. Then Freeswitch replies with a second REGISTER including a large "Authorization: digest" section with cnonce and nc=00000001 parameters.
The gateway which doesn't register, doesn't send the "qop=auth" parameter together with the "401 Unauthorized", and then Freeswitch sends a "Authorization: digest" section on the second REGISTER with no cnonce or nc parameters.
I know very little abouth SIP, so I'm wondering what this "qop=auth" parameter means and how does it affect the registration process. Is there any way to do without the qop=auth parameter?
Also, I tried registering with X-Lite directly to the gateway, and it worked, so it appears to be a problem in the Freeswitch/gateway combination. (Note: X-Lite sends an "Authorization: digest" section on the _first_ REGISTER, apparently this makes a difference)
Attached is a sip trace for the registration traffic when doing "sofia profile external restart reloadxml" on the cli, captured with "tshark -i eth0 -o "rtp.heuristic_rtp: TRUE" -w /tmp/capture.pcap -b filesize:51200 -b files:100 -R 'sip or rtp or icmp or dns or rtcp or t38'"
Thanks!
Nicolas
