[VoiceOps] Fax

[Nathan Anderson]

If you mean actually *offering* the e-fax solution in lieu of a
"fax-compatible" analog/FXS port off of an ATA, and not just shooing the client
off to someone else to get their fax needs fulfilled, that to me just sounds
like more work.  The e-fax server naturally needs to interconnect with POTS
somehow to do what it needs to do, and unless your e-fax server is directly
wired up to some multi-channel TDM circuit, you are still going to have to deal
with T.38 to/from the e-fax server.  So you haven't actually eliminated that
part of the equation, though arguably it's easier to guarantee stable IP
service to a single server or server cluster that's sitting in a data center
somewhere, rather than be concerned with the quality of the internet connection
to each and every client.  But now you are having to maintain another server
and another service.  (If you are already doing the hosted-PBX thing, then
perhaps maintaining yet another service in The Cloud(tm) is no big deal,
though.)

What are everyone's thoughts on trying to do fax this way, versus, an E-Fax
solution that supports receiving as well as sending ?

 

How many legit physical fax machines are you all supporting out there?

    I can echo, that the ATA matters. But so does the configuration of the
    faxing device (14400 Baud and ECM on), the switches that the calls go
    through, the configuation of the network equipment and the quality of the
    internet connection, even the cable type connecting the ATA and the fax
    device sometimes.

    I have excellent faxing history with Cisco ATA-191's using G.711 (but not
    T.38 with the softswitch I use predominantly) and a client network with
    well configured QOS enabled firewalls. 

    It's not logical to me, but I've even seen instances where using a 2
    conductor cable from fax to ata improved communication over a 4 conductor
    cable.

    Nathan and Ross covered other great points as well.

        Hi VOIPOPS Community

         

        Do you know about any fax over internet solution that works? We tried
        multiple ATA and multiple ATA configurations, sometime it works
        sometimes not.

         

        Also, do you know about any eFax solution provider that works good.

         

        Thanks in advance for your help.
