[cisco-voip] vg224 sanity check

[Ed Leatherman]

Good morning!

I have a remote campus with 1 VG224 (SCCP controlled) and a handful of
ATA's for analog service to fax machines etc.

IT staff on-site is complaining now that faxes on the VG can no longer send
faxes (they fail usually during the first page), whereas faxes via ATA are
ok oddly enough.

Kicker to me is they've also stated that even faxes between two devices on
the VG224 are having the same issue.

To me this along with the ATA's actually working OK seems to make a PRI or
network issue less likely although not ruling it out in case they are just
reporting things wrong to me. They also say no changes were made to gateway
(which I believe cause they prob don't have the login for it) or on their
CUCM.

My question though for anyone familiar with these is, if two devices on the
gateway are talking to each other via FXS ports, is this signal just
getting switched natively on the gateway? Is any signal conversion
happening or DSP's engaged at this point, assuming there aren't any
conferencing or such going on?

Thanks!
