Have you used a mobile phone when you test the "fast speed DTMF sequence"?<div><br><div>We have found that in GSM network DTMF digits are sent out-of-band from the terminal (despite the tones generated by phones) and are "injected" in-band into the audio channel _but_ with some delays between digits. At least this is the situation in Romania (Vodafone and Orange GSM networks).</div>

dahdi.conf is 80. This means that each DTMF key you press takes 80 ms to
transmit across the “line”. When mine got changed to 300, it made
my in-house calls take 2-5 seconds to connect and outgoing calls 7-11 seconds.
Genconf_dahdi changes this if you regenerate (I think).</span></font></p>

<p class="MsoNormal"><font size="3" face="Times New Roman"><span style="font-size:12.0pt">Hi,<br>
I'm new to this list<br>
<br>
I'm developing asterisk application where users can call and control volume up
and down in music player. <br>
Problem I'm getting is if users press 222228 in fast speed, system will process
all those 2s and then process 8, so there is few seconds ( around 4-5)
processing key press 8 , therefore users will feel unresponsiveness in
system.(in other words users will press those six keys in 2.5 seconds and it
will take 5 seconds to process them),its not application's problem. may be
within asterisk.<br>
<br>
this only happen when users call from physical phone, if they use softphone eg:
Xlite then this delay wont happen. <br>
<br>
think this is because network latency in telephony networks. Are there
any work around or possible solutions? Please anyone know, give me<br>
some idea.<br>
<br>
Thanks in advance<br>
Waruna.</span></font></p>
