Gateway Calls
Polycom®, Inc. 628
Once the participant is connected to the Gateway Profile and hears the IVR message requesting the
destination number, using the DTMF input keypad, the participant enters the number of the destination
endpoint followed by the # key. PSTN numbers are identified by an * before the number.
For example, enter 3456# for IP endpoint, or 9253456# for ISDN, or *9253456# for PSTN phone.
To enter an IP address as the destination number, replace the periods (.) with asterisks (*) in the format
n*n*n*n followed by the # key. For example, if the IP address is 172.22.188.22, enter 172*22*188*22#.

Direct Dialing Using IP Addresses
For Collaboration Servers registered to a gatekeeper, the Collaboration Server can be configured to dial and
receive calls to and from H.323 endpoints using the IP address in the event that the Gatekeeper is not
functioning.
Dial-out Calls
For Dial-out calls, direct IP dialing is enabled or disabled by the GK_MANDATORY_FOR_CALLS_OUT
system flag.
