Hi all
Though dial-peer 100 seems a little strange, but actually it is
fine, let me explain the call leg match chain for you.
1. dial-peer 4000 Inbound call leg match
When a voip
incoming call is reached at this router, because incoming called-number has the
highest priority, this command is matched.
2. dial-peer 100 outbound call leg match
Because for
outbound call leg match, only destination-pattern is used to select a call leg,
at this step service aa command is not effective.
3. dial-peer 100 inbound call leg match
Again, the call
reached at the router again, because step 2's session target is a loopback
address. Also, at this step, the service aa command is effective.
Could anyone help to confirm my explanation by issue show call
active voice brief? Thanks.
