Hi Tim,<br><br>Thanks for your reply. I am not using any fax software. I just created two extensions in trixbox (Asterisk 1.4), one extension I configured in one SPA3102 here FAX machine is connected in the phone port of SPA3102. <br>
<br>As the same the other extension is configured in another SPA3102 and FAX machine is connected in the phone port of SPA3102.<br><br>I am sending FAX from one extension to another extension. I am not able to send. <br>
<br>
This is how my workflow is designed. <br><br><div class="gmail_quote">On Thu, Sep 9, 2010 at 7:29 PM, Tim Nelson <span dir="ltr"><<a href="mailto:tnelson@rockbochs.com">tnelson@rockbochs.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">

<br></div><div>As I understand it, without FFA or some of the patches floating around, Asterisk is not T.38 gateway aware. Without more information, it's hard to pinpoint the issue, but as a first step, I would *DISABLE* the 'FAX Enable T38' parameter on the SPA3102. This will not help the reliability, but you may see the calls go through properly.</div>
<div><br></div><div>A packet capture is always helpful as well. tcpdump on the Asterisk box or Wireshark on a box connected to your switch's mirror/span port will do.<br><br>Tim Nelson<br>Systems/Network Support<br>Rockbochs Inc.<br>

Call Waiting Serv:No<br>>
Three Way Call Serv:No<br>>
Preferred Codec:G711u<br>>
FAX Passthru Method:ReINVITE<br>>
DTMF Tx Mode:Normal<br>>
FAX Enable T38:yes<br>>
<br>>
After all these changes still I am not able to send the fax, while
checking in the rtp debug from SPA3102 to Asterisk the sequential no. 0
but whereas from Asterisk to SPA3102 I can able to see some rtp traffic.<br>>
