[cisco-voip] Call Setup Failure on Gateway

[Bryan Nowak]

Hi,

My company moved a site over the weekend and our MPLS provider dropped a new
circuit in our old building.  So we've got a temporary VPN set up over a DSL
ckt until our T1 gets sorted out.

The problem we're having is that all inbound calls from the PSTN are
failing.  Callers hear dead air and then an error message when the timeout
finally expires.  Outbound calls are not experiencing any problems.

Debugging h225 shows that the gateway never gets a response to the setup
request from the CallManager.

at state H225_REQ_FS_SETUP

Can anyone offer any ideas as to why call setup between CallManager and the
gateway works fine on outbound calls but not inbound?

Any ideas will be much appreciated.
