Whats the difference between

dial-peer voice 1 pots

incoming called-number .

direct-inward-dial

and

dial-peer voice 1 pots

incoming called-number .

direct-inward-dial 2...

My extension are starting from 2100 to 2199 and DID are starting from 700 to 999. Which one is best and why? Second do i need to use port command?

Hello ,

incoming called-number - to recieve the digits

direct-inward-dial - to avoid second stage dialing.This command to enable the DID call treatment for an  incoming called number. When this feature is enabled, the incoming call  is treated as if the digits were received from the DID trunk. The called  number is used to select the outgoing dial peer. No dial tone is  presented to the caller.

You can configure either of these.

dial-peer  voice 1 pots

incoming called-number .

direct-inward-dial

or

dial-peer  voice 1 pots

incoming called-number 2...

direct-inward-dial
