Dialing from H.323 Endpoints
Chapter 18-Gateway Calls
Figure 18-1Dialing String and Call Flow from H.323 Endpoint to One, Two or Three Endpoints
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.
