[asterisk-users] NO ANSWER before playback or background function?

[Zhang Shukun]

hi,all

i find in asterisk 1.6.2.1, before play a sound file use playback or
background, it will answer the channel first.

but i want to answer the channel when dial someone and pick up the
phone.not play a file.

i know there are some params such as 'noanswer' for playback or 'n'
for background can not answer before play a file.

but it is not always take effect on my tests.as it said:

noanswer: Play the sound file, but don't answer the channel first (if
hasn't been answered already). Not all channels support playing
messages while still on hook.

Could you help me ?

Thanks!
