[asterisk-users] Inserting a wait in a sip dial SOLVED (kind of)

[Jim Dickenson]

If you need to inject dtmf tones or sound into an existing channel you can use chanspy with option w. I play sound files using the AMI to originate a call to an extension that does chanspy on one leg and a playback on the other.  I use channel variables to say which channel to play to and which sound file to play. SendDTMF or Playtones should be able to inject tones.
