Gateway to Gateway H.323 trunk

Unanswered Question
Jul 18th, 2007

Hi,

I'm fairly new to the callmanager and was after some advice/direction on trying to set up the following lab environment.

I have a 2821 gateway connected to the PSTN via PRI ISDN. Callmanager 4.2 setup and able to make outgoing calls.

Now, I have added another callmanager (seperate cluster) to the same internal network and was wanting to connect it to a second 2821 router. I was wanting connect this second gateway to the first gateway via a H.323 trunk. Some advice on how to begin setting this up?

First gateway: 2821 router

internal IP: 192.168.1.1

external PSTN: PRI ISDN

Second gateway: 2821 router

internal IP: 192.168.1.2

Do I setup a H.323 trunk between 192.168.1.1 and 192.168.1.2 and can I then route calls the the first callmanager that then will route external calls out the first gateway's PSTN link.

Thanks in advance...

I have this problem too.

PSTN -- 2821-A --- 2821B --- CCM2

This 2821 should allow connections from h323 to h323.

You only need to create dial-peers in both routers...

in 2821B doing the dialplan that match dial-peer pots in 2821A.

in 2821A dial-peer VOIP for incoming calls from PSTN to CCM2.

Thanks for the reply.

How do I create an endpoint on the 2821B? It is only connected via ethernet port (not to PSTN).
