AS5400HPX & PGW2200 in nailed mode

Hello all,

I am facing some very strange problems related to FAX calls on some AS5400HPX used with a PGW2200 nailed mode config. Basically some destinations are simply not working for the FAX calls or, in the best case, at a very high failure rate (1 of 3-5 successfull). Into the same network there is also one AS5300 NOT configured for SS7, which does not manifest the problem! the configs are simply identical and using the same voice routing scheme (GK's).

Any ideea will be more than appreciated.

Are you running same version IOS and SPE firmware on these two gateways?

Not now.

We have tried more than one IOS versions on 5400HPX and the behavior it's the same. It looks it's depening on the remote allocated GW (routing via GK) out to PSTN but I am not able to understand why the AS5300 works OK (also running 12.3 IOS).
