ekiga can't authenticate with SIP registrar

Bug Description

Binary package hint: ekiga

If I try to connext ekiga to the SIP registrar on my Fritz.Box, authentication always fails.
The reason seems to be that ekiga answers with a fantasy nonce that the server rightfully rejects:

19:45:02.408233 IP fritz.fonwlan.box.sip > laptop.local.1024: SIP, length: 479
WWW-Authenticate: Digest realm="fritz.box", nonce="A3078DB55DD74138"
User-Agent: AVM FRITZ!Box Fon WLAN 7170 29.04.76 (Jul 13 2009)

19:45:02.423782 IP laptop.local.sip > fritz.fonwlan.box.sip: SIP, length: 697
User-Agent: Ekiga/3.2.5
Authorization: Digest username="622", realm="fritz.box", nonce="E89133C4CB4A9D9B", uri="sip:fritz.box", algorithm=MD5,

For comparision, a successful connect with correct nonce handling by the client:

20:08:03.276538 IP laptop.local.1024 > fritz.fonwlan.box.sip: SIP, length: 4
WWW-Authenticate: Digest realm="fritz.box", nonce="F8F0D674D1AD00FD"
User-Agent: AVM FRITZ!Box Fon WLAN 7170 29.04.76 (Jul 13 2009)

20:08:03.311674 IP laptop.local.1024 > fritz.fonwlan.box.sip: SIP, length: 528

Please try the latest Ekiga version:

If it is still the same, I'll forward the issue upstream... We will need a complete debug output:

Best regards,

I encountered the same problem. I have attached a debug output of ekiga. Not sure if it is an ekiga problem.

I checked with the ekiga from the ppa, ans it too breakes the protocol by ignoring the nonce and inventing its own,
