Dial peer CSV file

This reference topic describes the structure and content requirements for a Dial Peer CSV (Comma Separated Values) file. This file includes information for one or more incoming and outgoing SIP and POTS dial peers, allowing for bulk configuration or import into Cisco SD-WAN Manager.

The file must be comma delimited, and each record in the file must include each field that the following table describes, in the order shown.

Table 1. Dial peer CSV file
Field	Description
Dial Peer Tag	Number that is used to reference the dial peer.
Dial Peer Type	Type of dial peer that you are creating (pots or voip).
Direction	Direction of traffic on the dial peer (Incoming or Outgoing).
Description	Description of the dial peer.
Forward Digits	How the dial peer transmits digits in outgoing numbers: All—The dial peer transmits all digits in the number. None—The dial peer does not transmit digits in the number that do not match the destination pattern. n—The dial peer transmits the number of right-most digits in the number that the integer n represents. For example, if n is 7 and the outgoing number is 1112223333, the dial peer transmits 2223333.
Preference	For POTS dial peers, a unique numeric value for the dial peer. If dial peers have the same match criteria, the system uses the one with the highest preference value.
Prefix	Digits to be prepended to outgoing POTS dial peer calls.
Numbering Pattern	String that the router uses to match incoming calls to the dial peer.
Dest. Address	Network address of the remote voice gateway to which calls are sent after a local outgoing SIP dial peer is matched.
Voice Port	Voice port that the router uses to match calls to the dial peer. For an outgoing dial peer, the router sends the calls that match the dial peer to this port. For an incoming dial peer, this port serves as an additional match criterion. The dial peer is matched only if a call comes in on this port.
Transport Protocol	For SIP dial peers, transport protocol (TCP or UDP) for SIP control signaling.
