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.)

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

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. Mark On 4/18/2024 10:22 PM, KARIM MEKKAOUI via VoiceOps wrote: 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.
