[cisco-voip] VG248 and SG3 faxing

We have used a VG248 for our G3 faxes for years and no issues.  Now we
upgraded one fax machine to SG3 and it is having all sorts of issues.  Call
Flow is

PSTN> H323 Gateway (with PRI) > Call Manager 4.3 (sr6) > VG248 > Fax Machine

I knwo with MGCP gateways there is the SG3 to G3 command to remedy this
situation, does that mean I need to upgrade the H323 Gateway to MGCP to fix
this or is there somethign I can do on the VG248 to remedy this situation.

Symptoms, incomplete faxes, receiving only cover sheet on multi sheet faxes,
and disconnects. (same issue we had with SG3 on FXS port on router but MGCP
line config fixed that issue.

Thanks

Kevin
