Goal
To explain HMR Sip Manipulation Execution Priority.
Solution
It is possible to specify sip manipulation rule sets in realms, sip-interfaces, and session agents however only one rule will be executed per ingress and one per egress dependent upon the following priority's:
1-Session-Agent
2-Realm
3-Sip-Interface
Rules specified in the SESSION-AGENT for an ingress(or egress) flow will be executed first, all other rules will be ignored for this particular ingress(or egress) flow.
Rules specified in a REALM for an ingress(or egress) flow will be executed if there are no rules specified in the associated session agent, rules specified in the associated sip-interface will be ignored.
Rules specified in a SIP-INTERFACE will only be executed if there are no other rules specified in the associated session agent or realm.
Furthermore:
If there are 3 sip-manipulations setup on the ingress flow called in the realm, sip-interface and session agent only the rule specified in the session agent will fire, the rest will be ignored. If there are 2 rules specified in the realm and sip-interface only the rule in the realm will be executed, the rule in the sip-interface will be ignored. A rule specified in the sip-interface will only be executed if there are no rules specified in the session agent or associated realm for the same ingress(or egress) flow.
