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>(218)727-4332 x105<br><br>----- "Gopalakrishnan A.N" <saigop@gmail.com> wrote:

it is working.<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>>

Your help would be much appreciated....<br>> <br>> <div class="gmail_quote">> On Tue, Sep 7, 2010 at 10:30 PM, Gopalakrishnan A.N <span dir="ltr"><<a href="mailto:saigop@gmail.com" target="_blank">saigop@gmail.com</a>></span> wrote:<br>>
