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.
* - to indicate 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.
** - to indicate 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.
