Switch to a Grandstream HT-701 or HT-502 and see if you get better results. The HT-286 has been discontinued for some time and the firmware has some major T.38 issues. <br />

<div style="text-align: left;"><span style="font-family: arial; color: #000000; font-size: 10pt;">I have been testing Fax For Asterisk with an analog fax sitting behind a Grandstream Handytone 286. I have been sending a number of faxes but I find that they send extremely slow. In my most basic test of sending from the HT286 straight to a tiff image on Asterisk on the same subnet I am seeing as much as 200 seconds to send a single page. Debug in the CLI shows that we are negotiating down to T.38 4800. I have disabled echo cancellation and noise suppression on the HT286 but with no change. I have tested with different fax machines (HP 1040 Fax and Sharp UX-B800SE) but with the same results. My Asterisk and FFA module versions are:</span></div>
