Between SoftCo9500s, the SIP trunk is the active trunk, and the TUP trunk is the standby trunk. When the SIP trunk is faulty, outgoing calls are routed to the TUP trunk. After the route configuration, however, calls cannot be connected to the other offices through the TUP trunk when the SIP trunk is faulty. Users cannot hear any announcements after dialing numbers, and the calls cannot be connected.
Step 1 Run the show tkc command to view the physical link of the trunk.
Step 2 Verify that the SIP trunk and TUP trunk can be used separately to connect outgoing calls.
Step 3 Run the show peercomponent domainnameXXX command to check whether the HeartBeat parameter of the SIP trunk is set to YES.
In the command, XXX indicates the actual domain name of the SIP trunk. If HeartBeat is not set to YES, run the config modify peercomponent domainname xxx heartbeat yes heartbeatperiod 5 command to enable the heartbeat.
Step 4 If the fault persists, contact Huawei technical support engineers.
The possible causes are as follows:
The physical link of the trunk is faulty.
Trunk connection data is configured incorrectly, and the link is not connected.
