Normal Request Egress Realm Precedence

For normal request routing, the egress realm precedence occurs in the following way (in order of precedence):

Egress SIP-NAT realm, when the route-home-proxy parameter is set to forced and no local policy match is found
Matching local policy realm, when configured in the local policy attributes
Session agent realm (set in the realm-id parameter) or the wildcarded value
Session agent egress realm, when configured in the egress-realm-id parameter
Global SIP configuration egress realm, when configured in the egress-realm parameter
Global SIP configuration home realm
