Issue Description

U1910 - Some of the outgoing calls through AT0 trunk  fail with voice prompt "Your call cannot be completed now".

Alarm Information

None

Handling Process

1. Gather information about the current configuration of U1910 to check the configured trunks and user rights:

Show version

Show license

Show board

Show subscriber dn xxxx type all                       (xxxx is the extension number which is trying to make the call)

Show trunkgroup

Show trunkgroup no xx                       (xx is the trunkgroup number from the above command output)

All settings are ok until now.

2. Check the analog lines one by one to make sure the cables connected are working properly.

After directly connecting an analog phone to each analog trunk line, we found out that one of the lines was faulty.

Root Cause

One of the analog lines was faulty. After replacing the cables, the issue dissappeared.

Solution

After replacing the cables, the issue dissappeared.

Suggestions

As an initial troubleshooting, inspect the current configuration to check user and trunk rights, which might forbidd outgoing calls.
