Dear Colleagues,
Since a MoH test case I would like to register two SIPp endpoints as a 3rd
party device (w. digest authentication) under a Cisco UCM, but I stucked.
Unfortunately I do not see any response from UCM after the authenticated
REGISTER, neither in the SIPp nor UCM log.
Here you can see the process:
1. Unauthenticated REGISTER request - SIPp > UCM
REGISTER sip:10.10.10.10;transport=udp SIP/2.0
Via: SIP/2.0/udp 10.10.10.20:5060;rport;branch=z9hG4bK-22782-1-0;alias
Route: <sip:10.10.10.10;transport=udp;lr>
Max-Forwards: 70
From: <sip:141@10.10.10.10>;tag=wE0HzCtlw8Ha9KJQ3hhWpgd3qJzehRIf
To: <sip:141@10.10.10.10>
Call-ID: 1-22782@10.10.10.20
CSeq: 30608 REGISTER
Contact: <sip:141@10.10.10.20:5060;ob>
Expires: 1800
User-Agent: SIPp
Allow: PRACK, INVITE, ACK, BYE, CANCEL, UPDATE, INFO, SUBSCRIBE, NOTIFY, REFER,
MESSAGE, OPTIONS
Content-Length: 0
2. TRYING - UCM > SIPp
SIP/2.0 100 Trying
Via: SIP/2.0/udp 10.10.10.20:5060;rport;branch=z9hG4bK-22836-1-0;alias

Call-ID: 1-22836@10.10.10.20

3. 401 Unauthorized - UCM > SIPp
SIP/2.0 401 Unauthorized
Via: SIP/2.0/udp 10.10.10.20:5060;rport;branch=z9hG4bK-22836-1-0;alias

4. Authenticated REGISTER request SIPp > UCM
REGISTER sip:10.10.10.10;transport=udp SIP/2.0
Via: SIP/2.0/udp 10.10.10.20:5060;rport;branch=z9hG4bK-22782-1-3;alias

I have registered an AVAYA device to see and compare the SIP log during the
registration. I saw one difference between the SIP logs, at the 4th step the
transport=udp is missing from the Authorization line, right after the
"uri=sip:10.10.10.10:5060"
I have no clue the CUCM why ignore the authenticated REGISTER request.
Have you seen this kind of problem before?
Do you have any idea?
Thanks in advance,
Laszlo
