We have one remote office is uisng FXS module (VIC3-4FXS/DID) to connect to their fax machine. The issue is sometimes they have problem to send out or receive the fax, sometimes they only can receive around 30% fax document from customer. The problem is inconsistance.
We use the CUCM 6.1 to set it up, are there any configuration I should add in CUCM or router could resolve this issue? Or how to do the troubleshooting?
Plug an analog phone to the FXS port and try to see if you can make a clean call. Make sure you have the ring-back tone over the FXS port. Also do " show controller T1/E1" and see if you have any slip errors.
"Show controller e1" is the first command that you need to use in order to troubleshoot this issue. Make sure you don't have slip errors under the controller. This is a common issue and most of the time is a Network Clocking issue.
