[asterisk-users] Passive wait in dialplan?

[Yaroslav Panych]

Unfortunately I don't know behaviour of Progress() function, so cannot
make any conclusions. As far as I traced it back to tech-
implementation, this call does not changes any state of channel. But I
analysed only sip and dahdi drivers. Neither it plays any indication
tones.

> 4- Asterisk on the base of that variable route the call further.

> 3- While(USERDECISION == "")
