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.<br>
<br>
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.<br>
<br>
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?<br>
<br>
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.<br>
<br>
Thanks for any and all recommendations.<span><font color="#888888"><br>
