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.

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

The dialing string 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)

22

Gateway Profile ID in GW A

9999

ISDN Dial-in Number assigned to the

 

Gateway Session Profile GW B

4444103
