External SIP Peer

On the External SIP Peer page, you can add or remove SIP servers or devices from the list of SIP peers to which the system can route calls and from which it may receive calls.

This is a supercluster-wide configuration. But note that a Polycom DMA system supercluster can provide proxy service for any or all domains in the enterprise, allowing the SIP function to be distributed, but managed centrally. This may reduce the need for external SIP peer servers (other than SIP session border controllers, or SBCs).

The following table describes the fields in the list.

Table 5-13Fields in the External SIP Peer list

Column	Description
Name	The name of the SIP peer.
Description	Brief description of the SIP peer.
Next Hop Address	Fully qualified domain name (FQDN) or IP address of
	the SIP peer
