Chapter 19-Gateway Calls

Polycom, Inc.

The calling endpoints can dial to one, two or several endpoints (up to ten) in one dialing 

string. 
The dialing string includes the following components:
[MCU prefix in GK] - the prefix with which the RMX is registered to the gatekeeper. 
[GW Profile ID] - The ID of the Gateway Profile to be used for routing the call to the 

destination endpoint or DMA, as defined in the RMX Gateway Profiles. It includes the 

parameters of the call to the destination.
* - indicates H.323, SIP or ISDN connection protocol to the destination endpoint (followed 

by the appropriate destination number). Placing this delimiter before the destination 

number causes the system to try to connect the endpoint using H.323 first, then SIP and 

lastly ISDN according to the selected protocols.
** - indicates a PSTN connection to the destination endpoint (followed by the appropriate 

destination number).
[Destination number] - the destination number as alias, IPv4 address or ISDN/PSTN 

number. 
The dialing string:
[MCU prefix in GK][GW Profile ID]*[Destination Number, first 
participant]*[Destination Number, second participant]**[Destination 
number]......*[Destination Number, tenth participant]

For example, If the MCU Prefix in the GK is 91 and the GW Profile ID is 2000, and the 

destination number is 3456 (SIP) enter: 912000*3456. 
To invite two participants: SIP: 3456 and ISDN: 9251444, enter: 912000*3456*9251444. 
To invite two participants: SIP: 3456 and a PSTN participant whose number is 9251234, 

enter: 912000*3456**9251234.
