H.323 Call Loop

[nokhao]

Is anybody know how to avoid loop in H.323 environment? As far as i know cisco H.323 GW uses call indentifier to detect a loop, but if the call is routed out to PSTN and get back into the GW the call indentifier is lost. Then the GW will never detect the loop.

As far as I know, you cannot use call Identifier to avoid loops when routed to PSTN
