I have got a major problem with my ATA and SIP Proxy Server setup. Whenever i try to enable authentication on the proxy server my ATA registrations drop immediately.
My protocol analyzer shows me that the registration is getting a 401 unauthorized (although the user is registered within the CSPS). Should i not get a 407 BTW from a proxy server when i'm being denied authentication ??
My ATA setup is pretty simple (using UID0 and PWD0), UseLoginID set to 0.
The error.log on the CSPS tells me that:
[Sat Mar 20 15:26:39 2004] mod_sip_authen.c(837) Digest
Not quite sure yet why CSPS is rejcting the registration. It is correct though for the CSPS to send a 401 response. 407 messages are sent when authenticating an INVITE message and not a REGISTER message.
At first glance it looks like the ATA is doing the right thing and sending the requested credentials back in the register message sent after receiving the 401.
Any chance we can get the sniffer trace for a good registration with Authentication?
Also, as a sanity check, please verify that the password that you defined in CSPS matches the password on the ATA
