Gateway Calls
Polycom®, Inc. 625
When the call is connected, a new Gateway Session is created and added to the ongoing Conferences list.
Dialing from H.323 Endpoints
The calling endpoints can dial to one, two or several endpoints (up to ten) in one dialing string.
Dialing String and Call Flow from H.323 Endpoint to One, Two or Three Endpoints
The dialing string includes the following components:
[MCU prefix in GK] - the prefix with which the Collaboration Server 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 Collaboration Server 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.
