[asterisk-users] Why does it take several seconds to interpret DTMF-input ?

[Eric Wieling]

The only way to resolve this is to redesign your dialplan so you do not have ambiguous matching,   This is not an Asterisk issue, this is an issue with the way you designed your dialplan and would apply to any IVR on any system.

		Dialplan :
		
		exten => ivr,1,NoOp()
		exten => ivr,n(restartprompt),Background(/var/lib/asterisk/sounds/vprompts/${KNUMMER}/${ASTPROMPT})
		exten => ivr,n,NoOp(${BACKGROUNDSTATUS})

		exten => ivr,n,GoTo(restartprompt)
		
		exten => _X,1,Set(choice=${EXTEN})
		exten => _X,n,System(echo "'${klantID}','IVR','${choice}','','${CHANNEL:4}','$(date +%s)'" >> /var/log/asterisk/loggingAST/${CHANNEL:4}.csv)
		exten => _X,n,other_stuff_I_do
		
		exten => _X.,1,Set(choice=${EXTEN})
		exten => _X.,n,System(echo "'${klantID}','IVR','${keuzeID}','','${CHANNEL:4}','$(date +%s)'" >> /var/log/asterisk/loggingAST/${CHANNEL:4}.csv)
		exten => _X.,n,other_stuff_I_do


	It is waiting for more digits because you have asked it for a possible multi-digit exten and it needs to distinguish between the _X and _X. patterns.

Ok thanks.

Any idea how I can resolve this ?

Even if there *can* be more than 1 digit, in case there is only 1 digit it should go faster.


Could this dialplan logic be a good solution :

[my-context]
exten => ivr,1,NoOp()
exten => ivr,n(restartprompt),Background(/var/lib/asterisk/sounds/vprompts/${KNUMMER}/${ASTPROMPT})
exten => ivr,n,NoOp(${BACKGROUNDSTATUS}) exten => ivr,n,WaitExten(15) exten => ivr,n,GoTo(restartprompt)

exten => _X,1,Set(choice=${EXTEN})
exten => _X,n,System(echo "'${klantID}','IVR','${choice}','','${CHANNEL:4}','$(date +%s)'" >> /var/log/asterisk/loggingAST/${CHANNEL:4}.csv)
exten => _X,n,other_stuff_I_do

exten => ivradvanced,1,NoOp()
exten => ivradvanced,n(restartprompt),Background(/var/lib/asterisk/sounds/vprompts/${KNUMMER}/${ASTPROMPT})
exten => ivradvanced,n,NoOp(${BACKGROUNDSTATUS})
exten => ivradvanced,n,WaitExten(15)
exten => ivradvanced,n,GoTo(restartprompt)

exten => _X.,1,Set(choice=${EXTEN})
exten => _X.,n,System(echo "'${klantID}','IVR','${keuzeID}','','${CHANNEL:4}','$(date +%s)'" >> /var/log/asterisk/loggingAST/${CHANNEL:4}.csv)
exten => _X.,n,other_stuff_I_do

[another-context]
...
...



Kind regards,
