Polycom 7000 manual Routed to this peer server

Device Management

Field	Description
Prefix range	The dial string prefix(es) assigned to this SIP peer.
	Enter a single prefix (44), a range of prefixes (44-47), or multiple prefixes
	separated by commas (44,46)
	If your dial plan uses the Dial services by prefix dial rule (in the default dial
	plan) to route calls to services, all dial strings beginning with an assigned
	prefix are forwarded to this SIP peer for resolution.
	If your dial plan instead uses a rule that you create to apply the Resolve to
	external SIP peer action, there is no need to specify a prefix.
	Otherwise, the system applies the SIP Routing settings of the originating site
	(see Sites and Edit Site Dialog) for calls to endpoints outside the enterprise
	network.
	Note: For a SIP peer, the dial string must either include the protocol or consist
	of only the prefix and user name (no @domain). For instance, if the SIP peer’s
	prefix is 123, the dial string for a call to alice@polycom.com must be one of
	the following:
	sip:123alice@polycom.com
	sips:123alice@polycom.com
	123alice
Strip prefix	If selected, the system strips the prefix when a call that includes a prefix is
	routed to this peer.
Register externally	Some external SIP peers require peers to register with them as an endpoint
	does, using a REGISTER message.
	Select this option to enable the External Registration tab and configure the
	system to register with this external peer server, following the rules specified
	in RFC 3261.
Supports SIP OPTIONS ping	If selected, the system sends SIP OPTIONS ping messages to the SIP peer
	to determine its responsiveness. See the Admin > Call Server > Call Server
	Settings page for configuration options related to SIP OPTIONS ping
	messages.
Domain List	If your dial plan uses a rule to apply the Resolve to external SIP peer action,
	you can restrict calls to this peer server to specific domains by adding the
	authorized domains to this list.
	If this list is empty, all domains can resolve to this peer.
	Note: In some circumstances (depending on network topology and
	configuration), dialing loops can develop if you don't restrict peer servers to
	specific domains.
Add new domain	Enter a domain and click Add to add it to the list of authorized domains.
Authorized domains	List of administrative domains, contained in the dial string, for which calls are
	routed to this peer server.
	Leave this list empty to route any call that matches the rule to this peer server.
	Select a domain and click Remove to remove it from the list.
