Release Reason / Cause Code Translation
Dialogic IMG Integrated Media Gateways ('IMGs') allow you to specify custom translation tables that map SIP reason codes to TDM reason codes. These custom cause code tables can then be associated with a channel group (under Cause Code Mapping Table) to allow the modification of cause codes if a SIP call leg fails to connect.
