Thanks for the post. Perhaps I should post what has been configured, maybe it'll help me see where I went wrong by seeing it once all the config is written down.
On the CUCM 6 side:
I have created:
SIP Realm: sip_africa.enterprise.root
Phone Security Profile: Nokia N97
Enable 'Digest Authentication' checkbox
Everything else left as default
Standard SIP Profile is being used (nothing changed)
3rd Party SIP Device (Basic)
Configured MAC Address C038F9E430C2
Phone button templete - 3rd Party SIP Device
Owner UserID : shaunsw
Device Security Profile: Nokia N97 (The one I created)
SIP Profile: Standard SIP Profile
Digest User: shaunsw
Directory Number configuration
DN 0621 (my DN)
Associated end user: shaunsw
On the Nokia N97:
Profile name: CUCM
Service Profile: IETF
Default Destination: Internet (This has my WiFi at work priority)
Access Point in use: None (As destinations are defined)
Public user name: sip:email@example.com
Use compression: No
Registration: Always on
Use security: No
Proxy Server Address: sip:172.21.34.163
Password: xxx (same as digest credentials)
Allow loose routing: yes
Transport type: auto
Server address: sip:172.21.34.163
password: xxx (same as digest credentials)
Transport type: Auto
I have also tried using public username: sip:firstname.lastname@example.org
Although today the phone just says: Not registered and not registration failed. On CUCM side, state uis Unknown.
Do you think it could be because the realm is not 'ccmsipline' (CUCM default) on both the SI Phone and the SIP Realm (I don't think it matters if you create your own SIP Realm) - I saw a guy having this issue with his integration on the forum relating to your previous posts.
I'm going to restart the phone now and check again if it works... can you see anything wrong here?
Got it Working, everything is the same as above, public username must be your DN (0621) and make sure in the proxy server and registrar server your username (as configured in CUCM ) is exactly as it appears, it is CASE SENSATIVE.
Other than that if you go to service parameters in CUCM you will see the SIP Realm (Even if you configure your own under user management) is set to ccmsipline, so make sure you use this realm when configuring your SIP Phone. You do not need to create one under end user. If you want to change this default ccmsipline change it under service parameters for the publisher server.
