Inbound Dial Peer Matching (by URI)
The inbound dial peer matching by URI feature allows you to configure the selection of inbound dial peers by matching parts of the URI sent by a remote (neighboring) SIP entity. The match is done on different parts of the URI like username, IP address, and DNS. This feature configures configuration policies, enforce specific call-treatment, security, and routing policies on each SIP trunk by originating SIP entity.
In a scenario where multiple SIP hops are involved in a call, there would be multiple via headers that are involved, and the topmost via header of an incoming SIP invite represents the last hop that forwarded the SIP request, and the bottom-most via header would represent the originator of the SIP request. This feature supports matching by the last hop that forwarded the request (neighboring SIP entity), which is the topmost via header.
Note |
For incoming dial-peer match based on URI, if there are multiple dial-peers matches, then the longest matching dial-peer is chosen (similar to multiple dial-peers match based on an incoming called number). However for the URI pattern match, there is no match length and hence this is the least preferred. |
