Outgoing calls over IP trunk failing 1

[ip22222]

Hello,

I have a H.323 trunk set up between an IP Office and an S8300/G450 (they are on different subnets). Calls to IP Office over that trunk are working fine. Calls from IP Office to the S8300 are failing (I dial, there's a few seconds of silence, and then the call drops).

If I trace the trunk (via the IP Office System Status), I see that the Short Code is properly matched, which should send the call over the proper trunk line. However, I then see that the Destination State is "Clearing", followed by "Disconnect from Destination End". If I do a "list trace tac xxx" on the S8300, I am able to verify the call never reached the S8300. I am able to ping from IP Office to the Call Server.

Any thoughts or suggestions would be appreciated.
Thank you.

You can better sniff the network as it looks to me that the IPO contacts the CM and the CM tells the IPO "who the hell are you, buzz off!" otherwise you would never had the message "Disconnect from Destination End", wich is a pollite way of IP Office saying "that monster does not want to talk to me..."
Read this IPO<--->CM

Thanks. Problem solved. Your post immediately made me think to check my ip node-names and that's where the problem was. I mistakenly entered the IP address of LAN1 for IP0, rather than LAN2 (I had them on different subnets for various reasons/testing scenarios).
