Some eSpace U1980 users cannot make calls. No matter what calls they make, an announcement is played, indicating that the number of call channels supported by the eSpace U1980 reaches the maximum.
Step 1 Check the configuration of an eSpace U1980 user that cannot make calls and locate the VoIP domain (corresponding to the voipdomain parameter) that the user belongs to.
Step 2 Run the show voipdomain command to check whether the value of maxcallnum for the voipdomain parameter is 0. The value is 0 indicates that the VoIP domain does not have the right to make calls.
Step 3 Run the config modify voipdomain id 0 maxcallnum 100 command to assign the call rights to the VoIP domain.
Step 4 Ask the user to make a call. The call is successful. No call channel limitation announcement is played any more. The fault is rectified.
The VoIP domain is incorrectly configured.
