And this warning when I call a extension at Siemens:<br>
<br>
WARNING[32744]: chan_dahdi.c:1938 dahdi_enable_ec: Unable to enable<br>
echo cancellation on channel 1 (No such device)<br>
<br>
Every time I call a extension on Siemens I've some mute moments for<br>
some of the call parts. It's quick, 4 to 8 seconds, but makes<br>
impossible to talk. And the caller has echo, always. It isn't a strong<br>
echo, but still.<br>
<br>
Another thing that is happening is that I just can call 5 digits<br>
numbers at Siemens, I think its a problem with the configuration at<br>
Siemens side, I already called the company responsible for the<br>
equipment to check if there is something wrong there.<br>
<br>
I've tried a several configurations until y-day when I got it working<br>
with Asterisk 1.4.22, DAHDI 2 and libOpenR2 0.1.1 - The most strange<br>
thing is that in a first moment using Asterisk 1.6 Beta and zaptel 1.4<br>
it worked close to perfectly, lets say 97%. And now I'm having this<br>
issues.<br>
<br>
I'm used to Asterisk and analog channels. But it's my first E1 and<br>
I've to confess that I'm not an expert, so maybe I'm missing something<br>
stupid here... I've a lot of doubts, so ...<br>
