Cause
The possible cause is that ZTE IMS cannot recognize the SIP registration message that
contains user=phone sent from the IAD.
Solution
Step 1 Run the sip soft-parameter sip-user-phone off command to disable the user=phone
information in the SIP message. The sip-user-phone attribute is enabled by default. You can
run the display sip soft-parameter command to view the sip-user-phone value.
Step 2 Check whether the fault is rectified.

If yes, the procedure ends.

If no, go to Step 3.
Step 3 Contact Huawei technical support.

2.3.13 IAD Cannot Register with the Softswitch Using MGCP
Symptom
The IAD cannot register with the softswitch using MGCP.
Cause
The possible causes are as follows:

The network is disconnected.

The configuration is incorrect.

The authentication information is configured on the IAD, but not on the softswitch.

The soft parameter settings are inconsistent.
Solution
Step 1 Check whether the softswitch can be pinged on the IAD.

If no, verify the network connection.

If yes, go to Step 2.
Step 2 Check whether the authentication settings on the IAD and softswitch are the same.

If the authentication information is configured on the IAD, but not on the softswitch, the
IAD cannot register with the softswitch. Ensure that the authentication settings are the
same on the IAD and softswitch.

If the authentication settings are the same, go to Step 3.
Step 3 Run the display mgcp soft-parameter command to check the MG soft parameter settings.
For Nortel devices, set MGC-TYPE to nortel, and registration mode to individual.
Step 4 Check whether the fault is rectified.

If yes, the procedure ends.
