I need to know that where on call manager 8.5 we configure the error codes.
eg. if a call from IP phone is going towards voice gateway and E1 connected to that gateway is down. Gateway will send a error code towards CUCM. So, i want to know where do we configure these error codes on call manager.
Which tells the CUCM how to behave or action based on error code generted.
There is a CallManager service parameter, Stop Routing on Q.931 Disconnect Cause Code, where you can enter any cause codes you want. Also in that section are how to handle routing when unallocated/unassigned is returned. Make sure you click the advanced button on the service parameters page to see all of them.
