Oops, meant to say that opermode should BE ok at default settings.<br><br><div><span class="gmail_quote">On 4/6/07, <b class="gmail_sendername">Michael Boers</b> <<a href="mailto:michaelscotttech@gmail.com">michaelscotttech@gmail.com

I am using a tdm400p with 4 fxo channels. I am in the US, so opermode should not be ok at default settings. I just recently got fxotune working on my system. The version that comes with zaptel
1.2.16 would simply hang. I am using the 1.4 fxotune now with the 1.2.16 driver. That has reduced the echo coefficient from 35% to 8%. We will see how that does.<br><br>--<br><span class="sg">Michael Boers</span><div>

</a> ) , it is<br>> suggested that one thing you can try to reduce echo is to insert a 500 ohm<br>> resister on the ring line of the POTS line. Has anyone successfully tried<br>> this? What was your experience. Also, what size 500 ohm resister would you

<br><br>Both of these play with characteristics of the card that are equivalent<br>to adding an extra resitor and also other similar changes.<br><br>--<br> Tzafrir Cohen<br>icq#16849755 <a href="mailto:jabber:tzafrir@jabber.org" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">
