</div>I made the change, did configure, make clean, make, & make install. I<br>
see this in the log now:<br>
2008-09-20 16:54:32 [DEBUG] switch_rtp.c:1201 do_2833() Send start<br>
packet for [3] ts=12560 dur=0/0/2000 seq=15883<br>
Before the duration would start at 160/160/2000. Is that what I should see?<br>
<br>
It still doesn't solve the issue. It doesn't act like I would expect.<br>
The server either 'hears' digits on a call or it doesn't; I would<br>
expect it to miss digits every now and then, not either completely<br>
pass or completely fail.<br>
<br>
What type of DTMF failure were you experiencing?<br>
<br>
I wonder if it is not a Freeswitch issue but an Exchange issue, I will<br>
get a SIP/TCP softphone and try to connect directly to the Exchange<br>
server. I think SJPhone does SIP/TCP.<br>
