Gaurav,

Nope, it is one single logical gateway. It has only one terminalAlias (something like voip-gw.hotmail.com). But it supports outgoing voice calls to area codes 408 and 409.

As specified in section 7.2.2 of H.323 V2 spec para 2 "The use of multiple transport addresses may simplify the routing of calls to specific ports". I am trying to simplify routing in my gateway.

Is the above statement in H.323 V2 correct now? Is there anyone on the list who has tried to do something like above?

Or is it that, to acheive my goal I have to divide my gateway into logical H.323 entities which I am not sure is needed. (if each registration of RRQ is allocated a different endpoint identifier then from GK perspective there are multiple H.323 entities).

Regards, -Chris

PS: Endpoint identifier is allocated by GK and returned to endpoint via RCF. (The same endpoint identifier will be used in keep alive RRQs.) If multiple RRQ's like I proposed in my original mail is allowed by H.323 V2 then the second RRQ would copy the endpoint identifier from first RCF.

Hi Chris, As per my understanding, you are talking of different logical

gateways

that are bundled together into a single *box*. Each such logical gateway

must

register with the gatekeeper. The terminalAlias could be used to

identify

the logical GW and the callSignalAddress would specify the contact point.

Hence,

you would have to send 2 RRQs. Also, the endpointIdentifier is generated

by the

GK and returned in the RCF and so cannot be specified by the GW at time

of

registration.

Any comments?

I have a question on RRQ registration in H.323V2. Let us say I have a gateway that supports area codes 408, 409. I want my gatekeeper to route calls to area codes 408 and 409 to my local TCP ports 2000 and 3000 respectively. How should I construct my RRQ message?

Shall I send two RRQs with same endpoint identifier (because I have only one gateway) with tuples <408, 2000> and <409, 3000>.

<x,y> means: x: carried in SupportedProtocols.prefix y: carried in callSignallingAddress of RRQ message

Is my understanding correct?

-Chris Rob
