These violations is definitely something we'll need to address as they certainly will contribute to the failing modem calls.

I've had problems with this myself.

What is the VG248's uplink to the network?

Is that port configured with any QOS settings? You must remember that VG248 is not marking layer 2.

Is your gateway using fax-passthrough or fax-relay?

Also, there are some settings on the VG port you should turn off for optimization. For instance, turn off CWI, and extra things like this.

Re: Unable to make dialup connection (data) through VG248

We had the problem with faxes

It seems data ethernet PATH between gateway (AS5350 in our case) and VG248 must be fixed in link speed (no auto negotiation) ->

speed 100

duplex full

It seems those packets made problems sometimes.
