Troubleshooting DID Numbers
If calls to the DIDs you configured are not forwarded as expected:
- Click on the “Activity Log” tile in the “Dashboard” function in 3CX Management Console to see current server activity and log entries for received calls and their destination number.
- Call a configured DID number while monitoring the “Activity Log” for a line similar to:Incoming call from “10000” to <sip:789456123@3CXPhone System>where “10000” is the internal number of the line configured to receive calls from the VoIP gateway or VoIP provider and<sip:789456123@3CXPhone System>is the content of the “To” header of the INVITE, i.e. the intended recipient. Note: The “Logging level” can be set in “Activity Log” > “Settings” to “Medium” or “Verbose” to see additional messages.
- Analyse the “To” header carefully to ensure that the configured DID number is present in the header, e.g. <sip:789456123@3CXPhone System>. Some providers use the “Request Line URI” field.
- Reconfigure the number if needed.
