Looking for some troubleshooting tips on cisco's VG224 particularly faxing. The VG224 is connecting to our CUCM 7.1.3 server. Right now I am having an issue with a 2 faxes 1 fax doesn't even answer when you call the extension(5231) the other fax answers (5047) but doesn't receive the fax. We had some fax technicians come out and they said the issue is internal to our network. I rebooted the VG224 that they are connected to and now I can receive faxes on 5047 but 5231 still doesn't pick up.
Are there any commands that would show bad ports on the VG224? Or a command that would let me debug the traffic? Or even something in the CUCM server that shows something wrong. Any help is appreciated.
