Calling A Sip Endpoint In A Remote Domain - Polycom realpresence 1800 Administrator's Manual

When the flag is set to NO (default), if the Gatekeeper is not functioning, calls from endpoints will be
connected directly to the Entry Queue, Conference or Meeting Room that was dialed.
The method by which dial-in calls are accepted or rejected is dependant on the flag value and the availability
of the Gatekeeper as summarized in the following table.
GK_MANDATORY_FOR_CALLS_IN - System Flag
Flag Value Gatekeeper Available
NO NO
NO YES
YES NO
YES YES
Enabling or Disabling Direct IP Dialing
The direct IP dialing is enabled by default. To disable it, manually add the flags
GK_MANDATORY_FOR_CALLS_OUT and GK_MANDATORY_FOR_CALLS_IN to the System
Configuration - MCMS_PARAMETERS dialog box and for each flag enter the required value (YES or NO).
For more information on flag definition,
For flag changes (including deletion) to take effect, reset the Collaboration Server. For more

Calling a SIP Endpoint in a Remote Domain

The Gateway functionality allows the connection of H.323 and SIP endpoints to SIP endpoints residing in a
remote domain, different to that of the MCU's domain.
This functionality can be enabled when:
● The calling endpoint may be H.323 or SIP.
● The destination endpoint must be SIP.
● The dial string from the calling endpoint to the Collaboration Server includes the gateway dial-out
number of the SIP endpoint that is located in the remote domain.
By definition, a dial-in string cannot contain two domains and it is therefore necessary that the dial string be
of the following format:
mcu-meeting-room*dest%40dest-domain@mcu-domain
Where:
● The domain of the gateway call is mcu-domain
● The remote destination domain is dest%40dest-domain.
● The "%40" is replaced with an "@" when the gateway call is dialed to the remote SIP destination.
