<br>
I am comparing this with an Asterisk and FreeSWITCH installation, using the same route, same codecs, same carrier, same phones and same servers… :P<br>
I experience a delay when pressing DTMFs on the line that uses FreeSWITCH. I am estimating the delay to be around 500 ms.<br>
<br>
What are the settings I can fine tune to avoid this?<br>
<br>
All the best,<br>
Emrah<br>
