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 .


dial-peer voice 9000 voip

destination-pattern 3...

session target ipv4:

dtmf-relay h245-signal h245-alphanumeric

no vad

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.
