[asterisk-users] Passive wait in dialplan?

[Yaroslav Panych]

I don't know much about queues, but if channel enter into queue it
should not change its state. I.e. not answer, no moh, no interacting
with user input(DTMF). Less I use unknown helpers, better my
configuration is.
Second issue which can appear using queues - its async state. User can
issue 2 serial commands, and I should have synchronisation tools. In
dialplan I using UserEvent application - which issues event in AMI,
with given data headers. Queue - is there any possibility to customise
queue join(or like) AMI event? Without patches(I already have made
some patches to core and wrote additional module to make * work as I
require).
