The SoftCo9500 connects to the information management system (IMS) platform through the SIP trunk. An outer-office user dials the access code of a SoftCo VU switchboard, and dials 0 to switch to the attendant service. If no one answers the call and the user hangs up, the phone of the attendant service still rings for dozens of times.
Step 1 Check the configuration.
1. Run the show ims connectpara command to view the domain name of the IMS.
2. Run the show peercomponent command to view the domain name of the peer device.
3. Run the show protocol sip command to view the domain name of SIP.
Step 2 Verify that the preceding domain names are the actual IMS domain names.
If the domain name in the connectpara parameter is incorrect, run the following command:
config modify ims connectpara domainname XXX
If the domain name in the peercomponent parameter is incorrect, run the following command:
config modify peercomponent domainname XXX
If the domain name in the protocol sip parameter is incorrect, run the following command:
config protocol sip officeno N domainname XXX
In the preceding command, N indicates the office route code of SIP.
Step 3 If the fault persists, contact Huawei technical support engineers.
The possible cause is that the SoftCo configuration is incorrect.
