Call Server Configuration

For this action:	The system attempts to resolve the address as follows:
Resolve to external SIP peer	Checks the domain of the dial string against all of the rule’s selected peers, looking
	for a peer proxy responsible for that domain. If the dial string matches the domain
	of one of the selected SIP peers, this rule will either successfully route the call, or
	the call will be aborted; no subsequent dial rules will be attempted.
	After selecting this action for a rule, select a Routing policy. The policy affects the
	way the system resolves dial strings to SIP peers:
	• All in parallel (forking)
	The system uses all SIP peers simultaneously to try to resolve the dial string.
	• Weighted round-robin
	You can assign each SIP peer a weight in the range 1-100, with a higher weight
	giving a SIP peer higher priority; the system tries each SIP peer sequentially
	according to the SIP peer’s assigned weight. You can assign a SIP peer
	different weights in different dial rules.
	After choosing a routing policy, move the SIP peers to which the rule applies from
	the Available SIP peers box to the Selected SIP peers box. If the Weighted
	round-robinrouting policy is selected, choose a weight for the selected SIP peer
	using the Edit weight button.
	Note: This action employs the H.323<->SIP gateway function if applicable.
Resolve to external	If the dial string appears to be an H.323 alias, simultaneously sends LRQ
gatekeeper	messages to all of the rule’s selected gatekeepers.
	After selecting this action for a rule, move the gatekeepers to which the rule applies
	from the Available gatekeepers box to the Selected gatekeepers box.
	Note: This action employs the H.323<->SIP gateway function if applicable.
Resolve to external address	Determines if the dial string is a well-formed instance of an external address type to
	which the rule applies, and if so, uses the resolution procedures specified in the
	applicable standard for that address type.
	After selecting this action for a rule, select the address type or types to which the
	rule applies. The address types and applicable standards used to resolve them
	are:
	• SIP URI: RFCs 3261 and 3263
	• H.323 url-ID: H.323 specification, Annex O
	• H.323 Email-ID: H.225.0 specification, Appendix IV
Resolve to conference room	Looks for a conference room (virtual meeting room, or VMR) that matches the dial
ID	string.
Resolve to virtual entry	Looks for a shared-number entry queue that matches the dial string.
