Polycom 7000 manual Block Blocks the call Resolve to IP address

Call Server Configuration

For this action:	The system attempts to resolve the address as follows:
Block	Blocks the call.
Resolve to IP address	Tries to treat the dial string as an IP address, and if it can, assumes it’s the address
	(and port, if included) of an unregistered endpoint. If no port is specified, it uses the
	default port of the signaling protocol.
	If the dial string contains the characters “##,” it tries to do this using the characters
	before “##.”
	For SIP:
	• If the domain part is an address not controlled by the RealPresence DMA
	system (or supercluster), the dial string is resolved unchanged.
	• If the domain part is an address controlled by the RealPresence DMA system (or
	supercluster) and the user part is an IP address (and possibly “##”), the user part
	is resolved to a SIP URI.
	• If the characters before the first “##” resolve to an IP address, the characters
	after that are treated as the user part of a URI.
	For H.323, if the characters before the first “##” resolve to an IP address, the
	characters after that are converted into the destinationInfo (ACF) or
	destinationAddress (Setup) as follows:
	• If possible, encoded as a dialedDigits address.
	• Otherwise, if possible, encoded as a url-ID.
	• Otherwise, encoded as an h323-ID.
Resolve to registered	Looks for a registered endpoint (active or inactive) that has the same alias or
endpoint	signaling address.
	Note: This action employs the H.323<->SIP gateway function if applicable.
