I am trying to get a 7912 Cisco IP working with an internal SIP server. Was able to upgrade the firmware which I done successfully.
I config all the parameters via the phone web portal. However, when the config try to register with the sip server, I got unauthorized.
U 209.150.20.xxx:5060 -> 10.x.x.x:5060
SIP/2.0 401 Unauthorized..Via: SIP/2.0/UDP 10.11.xx.xxx:5060;branch=z9hG4bK8608f52fabad5954;rport=5060..From: <sip:firstname.lastname@example.org;user=phone>;tag=487436181..To: <sip:email@example.com
;user=phone>;tag=aead0692c84c8b6505e163c5a981d337.0754..Call-ID: firstname.lastname@example.org..CSeq: 92 REGISTER..WWW-Authenticate: Digest realm="crazy.com", nonce="4a574cf0d737a2b3b72a5b3df4968198bd079
f72"..Server: OpenSER (1.2.0-notls (i386/linux))..Content-Length: 0....
"SIP/2.0 401 Unauthorized" is a password issue. The sip proxy is rejecting the call with the wrong username and password.
I really don't think that is a password issue, I triple checked the password and the username is the phone number of the phone.
Think it is something deeper than that.
Thanks for the answer though
