asterisk users - Feb 2016 - Grandstream Early Dial

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

Hi list,

I've been using Grandstream phones for more than 10 years, but only
yesterday tried to use Early Dial... and I failed. What is needed on the
Asterisk side to reply 484 to INVITE? Phones are talking to chan_pjsip
on Asterisk-13.7.1.


Thanks,

Look into the Incomplete application.

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,
