Issue Description
Registration of a Huawei eSpace 7850 (R001C03SPC220) connected to Huawei IAD208E(M) (V300R001C07SPC700) failed on the CUCM 8.6.2. But registration of the eSpace 7850 alone, succeeded. Please see attached print screen of this case. On the trace, when registration failed the Authorization Digest Username is “7101” and it must have been “iad208”.
Alarm Information
IAD replied: IP/2.0 404 Not Found
Handling Process
1. Check IAD Sip Service Configuration/SIP Soft Parameter -> Authentication type = ID
2. Change the Authentication type to Name of two IP Phones SIP accounts
3. Verify registration status -> Successful
4. Do incoming and outgoing test calls -> Successful
5. Change the Authentication type to Name to all the SIP accounts configured on the IAD
Root Cause
1. Check SIP user settings on the CUCM -> OK!
2. Check Account settings on the IP Phone -> User name: 7101 Register name: iad208
3. Check IAD Sip Service Configuration/SIP Soft Parameter -> Authentication type = ID
4. Change the Authentication type to Name
5. Retry the registration test scenario -> Success
Suggestions
If on the SIP server, you configure the Authentication by UserName, in the IAD this means that in the Sip Service Configuration/SIP Soft Parameter -> Authentication type must be set to Name, not to ID. Use this setting to avoid failed registration of the IP Phones connected to the IAD.
