<p class=""><span style="font-size:11pt;font-family:Calibri,sans-serif;color:rgb(31,73,125)">Thanks for the reply. I have been able to resolve this issue – looks like I had to explicitly choose the modem carrier (1200) using the +MS command.<u></u><u></u></span></p>
<p class=""><span style="font-size:11pt;font-family:Calibri,sans-serif;color:rgb(31,73,125)">However, curious to know a bit more on the echo canceller that you are referring to – we are using the Sangoma card with echo canceller, and I haven’t explicitly turned it off!<u></u><u></u></span></p>
<p class=""><span style="font-size:11pt;font-family:Calibri,sans-serif;color:rgb(31,73,125)"><u></u></span></p></div></div></blockquote><div>Echo cancellation is not a good idea in data calls. Mind you, depending on the type of data call there is variable tolerance. Also, some data calls (ie fax) start by sending a well-known tone that Sangoma echo canceller recognizes and then disables itself (see CED tone here: <a href="http://telecom.tbi.net/fax-call.htm">http://telecom.tbi.net/fax-call.htm</a>).</div>
