[cisco-voip] faxing

[Matthew Ballard]

Personally I would strongly recommend staying away from the ATA-186s for
faxing, they can work, but are more hassle than they are worth,
especially with newer fax machines or if the data connection isn't
completely clean.

 

>From my experience my preferred setup is:

1)      A centralized fax server with a fax machine able to communicate
through IP to the fax server (but only logical if you are implementing
it generally).

2)      FXS port on a router if one is already installed, or a VG2xx box
if there isn't a router that you can install an FXS port.  Routers/VG2xx
can do T.38, and can automatically force the connection speed down to a
level they are designed to handle.

3)      Worst case scenario use a ATA186, but make sure you disable v.34
on the fax machine

 

Also, I like using T.38 in MGCP mode if available for remote sites, as
it can better handle latency and jitter than g711.

Good Morning All,

 

I have a remote site needing fax capability, and presently that site is
configured for network connectivity( Computer and IP 7940).  Is it
possible to put a fax machine at this site without having to get a
telephone land line installed
