The allow-incoming calls feature is supported on an interface source pool. When the allow-incoming feature is enabled on a source pool (p1), the following format incoming_nat_p1 (or as incoming_nat_ge-0/0/0.0 for an interface source pool on an interface ge-0/0/0.0) is referenced in a policy. Similar to static NAT, such a reference can be used as a destination address in the policy configuration to regulate the VoIP incoming traffic and to perform destination IP and port number translations.
