[asterisk-users] delay in processing dtmf

[Danny Nicholas]

That's pretty much the same in US at least with AT&T and LG phones.

Have you used a mobile phone when you test the "fast speed DTMF sequence"?

 

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).

The default setting of tonedur in 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).

You might want to play with tonedur in dahdi.conf.  This IME effects SIP
calls as well.

Hi,
I'm new to this list

I'm developing asterisk application where users can call and control volume
up and down in music player. 
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.

this only happen when users call from physical phone, if they use softphone
eg: Xlite then this delay wont happen. 

think this is because network latency in telephony networks. Are  there any
work around or possible solutions? Please anyone know, give me
some idea.

Thanks in advance
Waruna.
