Gateway to Gateway Calls via ISDN Cascading Link

When H.323 participants connects to another IP participants via a Gateway to Gateway call
over an ISDN link, the dialing string includes the following components:
[GW A prefix in GK] - the prefix with which the RMX (gateway) is registered to the
gatekeeper.
[GW Profile ID] - The ID of the Gateway Profile defined on Gateway A to be used for
routing the call to the Gateway B.
[GW Profile ISDN/PSTN number] - the dial-in number assigned to the Gateway Profile
defined on Gateway B, including the required country and area codes.

number of participant B.
The dialing string format:
H.323 Participants connecting to another IP participant via a Gateway to Gateway call over an
ISDN link enter a dial string using the format:
<GW A Prefix in GK><Gateway Profile_ID on GW A>*<Destination ISDN
Dial-in number assigned to the Gateway Session Profile GW
B>*<Destination Number, participant>
For example:
GW A prefix in Gatekeeper - (not used with SIP)
Gateway Profile ID in GW A
ISDN Dial-in Number assigned to the
Gateway Session Profile GW B
IP Participant Alias
H.323 participant dials: 229999*4444103 and when prompted for the Destination number
enters 3456 followed by the pound key (#) using DTMF codes.

<Gateway Profile_ID on GW A>@<Central Signaling IP GW
A>*<Destination ISDN Dial-in number assigned to the Gateway Session
Profile GW B>*<Destination Number, participant>
For example:
If Central Signaling IP address of Gateway A is 172.22.177.89, SIP participant dials: 9999@
