[asterisk-users] Grandstream Early Dial

[Bryant Zimmerman]

Jean-Denis Girard
  
 I have not used the Incomplete yet, but you might be able to do something like this.
  
 [earlydial]
  
 exten => _.,1,Set(l_Extension = ${EXTEN})
 exten => _.,n,Goto(${l_Extension},1)
 exten => _.,n,Goto(noMatch,1)
  
 exten => i,1,Goto(noMatch,1)
  
 exten => noMatch,1, Incomplete(n)
  
 exten => _1XX,1,Verbose(2, Dialed ${EXTEN})
      same => n,Playback(extension)
      same => n,SayDigits(${EXTEN})
      same => n,Hangup()
  
  
 I wrote this in this message and have not tested this so use with caution. There may be syntactical issues, but the concept might work for you.

Thanks for prompt answer Richard.

Actually I had already tried the Incomplete application, but failed to
add the "n" option, and this seems mandatory for SIP. I find the help
text misleading : "NOTE: Most channel types need to be in Answer state
in order to receive DTMF".

This is my test dialplan:

[earlydial] ; Test Early Dial
exten => 1,1,Verbose(2,Incomplete 1 test)
same => n,Incomplete(n)

exten => _1X,1,Verbose(2,Incomplete 1X test)
same => n,Incomplete(n)

exten => _1XX,1,Verbose(2, Dialed ${EXTEN})
same => n,Playback(extension)
same => n,SayDigits(${EXTEN})
same => n,Hangup()

It works, but seems a bit complicated: is this the correct way to use
Incomplete ?

Thanks,
