Configuring SIP Error Message Pass Through

The Configuring SIP Error Message Pass Through feature allows an error response that is received from one SIP leg to pass transparently over to another SIP leg. This functionality will pass SIP error responses that are not yet supported on the Cisco Unified Border Element (Cisco UBE) or will preserve the Q.850 cause code across two sip call-legs.
