It is often advantageous to attempt to reroute a call in the event that a first route is down or refused.
Cause Code Reroute Tables allow you to create tables that specify to VX which release codes will trigger a reroute, which will make VX try the next matching route in the Call Routing table before returning a failure to the user. The most common reason is 3 - No Route - but all standard codes may be used, except for 16--Normal Clearing. (The CLI permits advanced entering of non-standard codes, if required.)
Cause Code Tables are selected in the Trunk Group configuration.
