SIP and ISDN use different response messages to communicate why a call failed or could not be connected (Q.850 for ISDN and SIP Responses for SIP). By default, the SBC Edge uses RFC 4497 to map these to each other. Override Tables allow you to override one or more of these mappings to a different message, which is useful for interoperating with nonstandard equipment. To use a table created here, select it from the SIP to Q.850 Override Tables field in a SIP Signaling Groups entry.
