Field	Description
Email IDs of registered H.323	Specifies that call requests for locally registered H.323 endpoints’ email IDs
endpoints belong to every local	don’t have to match the domain. For example, if there is an endpoint
domain	registered as ‘h323:johnsmith@1.1.1.1’ and this option is enabled, a call to
	'h323:johnsmith@mycompany.com’ may be connected to that endpoint.
	If this option is not selected, call requests must exactly match the URI of the
	registered endpoint.
Conference rooms and virtual	Specifies that if the dial string specifies a conference room (VMR) or virtual
entry queues belong to every	entry queue (VEQ) on the Polycom RealPresence DMA system and includes
domain	a domain, a dial rule implementing the Resolve to conference room ID or
	Resolve to virtual entry queue actions (such as dial rule #2 or #3 of the
	default dial plan) ignores the domain and routes the call to that conference
	room or VEQ.
	If this option is not selected, a dial string that includes a domain doesn’t match

Dial Rules

Dial rules specify how the Polycom RealPresence DMA system Call Server uses the dial string to determine where to route the call. This dial string may include an IP address, a string of numbers that begin with a prefix associated with a service, a string that begins with a country code and city code, or a string that matches a particular alias for a device.

Dial strings may match multiple dial rules, but the rules have a priority order. When the Polycom RealPresence DMA system Call Server receives a call request and associated dial string, it applies the first matched (highest priority) dial rule.

The Call Server comes with a default dial plan installed that provides the most commonly needed address resolution processing. On the Dial Rules page, you can add, edit, remove, and change the order of the dial rules that make up the system’s dial plan. This is a supercluster-wide configuration.

The Call Server can optionally have a separate dial plan used only for untrusted (“unauthorized” or “guest”) SIP calls. These are calls from devices not registered with the RealPresence DMA system and outside the corporate firewall (but not part of a federated enterprise). These calls typically come to the RealPresence DMA system via session border controllers (SBCs) such as a Polycom RealPresence Access Director or Acme Packet Session Border Controller device.

You can configure the system to recognize and accept such calls on the Signaling Settings page (see H.323 and SIP Signaling on page 72). On the Dial Rules page, you can create a separate set of “guest” dial rules used only for these untrusted calls.

A dial rule consists of an optional preliminary script to modify dial strings and the action to be performed, which you select from a well-defined list of actions. These actions encapsulate potentially complex dial resolution logic, which shields you from having to deal with these complexities.
