Hi, all
I have found the following dial-peer in several case stadies. It match all called number, but there is not voice port configuration under it. So what is the effort for this dialpeer?
---------------------
!
dial-peer voice 10 pots
incoming called-number .T
direct-inward-dial

A voice-port is not necessary if the pot dial-peer is specifically for direct-inward-dial (DID) only.
You may being using COR, in which case you would configure seperate outgoing POTs dial-peers, not the specific incoming.
In order for DID to work, you have to configure direct-inward-dial on the pots dial-peer.
The incoming comming called number is then used to match an outgoing dial-peer such as your CallManager VoIP. This is achieved by configuring the incoming-called-number on the same pots dial-peer.
Here is an example:-
dial-peer voice xy pots
description Inbound PSTN Dial-Peer
incoming called-number .
direct-inward-dial
dial-peer voice 9000 voip
destination-pattern 3...
session target ipv4:1.1.1.1
dtmf-relay h245-signal h245-alphanumeric
no vad

Allan,
Very very thanks for your reply.
Does this dial-peer mean DID is enable on the matched dial-peer? So it is necessary for DID, right?

Hi Tao, thanks for the appreciation.
DID is specifically required on the incoming call-leg, it allows the called number to match an outbound dial-peer based on the on the destination-pattern configured.
The incoming POTs dial-peer is matched using the incoming-called-number, and DID allows the outbound dial-peer to be matched directly from the called number.
From my previous example, say the Telco forwarded the digits 3456, the incoming POTs dial-peer will be matched using incoming-called-number . , and DID will directly match the outgoing VoIP dial-peer with the destination-pattern 3...
Hope this helps.
Allan.
