Grandstream ATAs for Faxing
Hello, We having been utilizing Grandstream ATAs (HT70X and GXW400X) as analog hand offs with our Hosted Services built on the Broadworks platform and Sansay's SBC. We've had regular trouble when using them with fax and credit card machines. We support t38 but have often gone to g711 pass-through. Echo cancellation is disabled. We've tested them with the various jitter buffer lengths, Rx/Tx setting adjustments and various impedance values. The results seem very inconsistent. This is site to site as well as inconsistent results at the same site. The faxing/credit card transmissions will work for a period of time and then begin failing without any changes. We are a CLEC who control the QoS from device out to the PSTN. We've found that replacing the ATA with a Adtran TA90X usually corrects the issues but this is not a cost effective solution. Anyone have similar experiences with Grandstream ATAs? Anyone have reliable VoIP faxing with their ATAs? If anyone has been successful integrating the Grandstreams, I would be interested in knowing what config changes you've made from their default. Which models you've used with which firmware? Anyone have other ATA's that seem to work well for faxing and credit card machines? We'd like to keep our offering to as few manufacturers as possible that can offer 2, 4, 8+ FXS ports. Thanks for any and all recommendations. Jamey Socket Telecom
We've had "OK" success with Cisco SPA112 ATAs.. I only say OK because there are a ton of caveats to it.. Any re-invite towards the ATA results in a momentary audio pause (just silence in the RTP, no RTP loss, awesome).. Provisioning? Need a signed cert from Cisco to support HTTPs.. LLDP-MED support seems to still be broken even in the latest releases.. Other than the annoyances there, they're actually not too bad. Good success with T.38 (but we generally just use 711u), and no real issues with credit card machines, etc.. -- Tim On Tue, Sep 9, 2014 at 7:39 AM, Jamey <jamesleo at socket.net> wrote:

An alternate route is to put you fax DIDs on a centralized fax-2-email platform. Thereby avoiding any ATA-related hassles. If done properly, will give you very satisfactory fax success rates On 14-09-09 10:39 AM, Jamey wrote:

Sadly people still need outbound fax.. Just wait until you have that user with an ATA and a fax machine faxing their fax->email service 40+ times a day to get documents via email.. -- Tim On Tue, Sep 9, 2014 at 8:33 AM, Victor Chukalovskiy <victor.chukalovskiy at gmail.com> wrote:

Send and pray is what I?ve always said with modems and voip. You can get it working about 98% of the time but there is always those gotchas that will make you pull your hair out and make you waste hrs and hrs or time.

I don't have any experience with Grandstream, but in my experience the "right" answer to FoIP is T.38, as you alluded to. But T.38 *only* deals with faxing; it is *not* a general-purpose modem-signal-over-IP solution. So even if you find an ATA with a good T.38 implementation, this is not going to solve your credit card machine problem, only your faxing problem. The equivalent to T.38 for bi-directional modem traffic over VoIP would be V.150, which as far as I know is very much still in its infancy, with very little industry support as of yet (either on the telco side or on the equipment side). So your only solution for the credit card machines would be to continue to carry the traffic as G.711 PCM, which is never going to be predicably reliable. My advice would be to implement T.38 on your network, deploy T.38 CPEs/ATAs to your customers, tell them that faxing is supported, but that any application they have that requires a modem (credit card swiper, postage meter, security system, etc.) is not, and that they should work with their vendor(s) to upgrade their modem-based equipment to models that support an ethernet/direct IP connection instead. -- Nathan Anderson First Step Internet, LLC nathana at fsr.com
For faxing, HTTPS faxing using Audiocodes adapters with Faxback technology has been the only reliable solution for us. Not sure about credit cards. T38 seems to be a joke. On Tue, Sep 9, 2014 at 9:39 AM, Jamey <jamesleo at socket.net> wrote:

Oh god. We've had horrid results with the Faxback platform. We've used it with two resellers and it's been consistent downtime. That could be the resellers and not the platform itself. I agree on T.38 though. We disable it by default and use G711 over Mediatrix or Adtran ATA's with pretty good results. dw On Wed, Sep 10, 2014 at 8:32 AM, Colton Conor <colton.conor at gmail.com> wrote:
