mentions that the PITCH_SHIFT() function is designed to be used
dynamically and can change the pitch of a channel on the fly
using features.conf. Can someone provide me with any information of how
this would be accomplished for dynamic use? I'm familiar with the
dialplan syntax use examples such as:
exten => 1,1,Set(PITCH_SHIFT(tx)=highest); raises pitch an octave
exten => 1,1,Set(PITCH_SHIFT(rx)=higher) ; raises pitch more
exten => 1,1,Set(PITCH_SHIFT(both)=high) ; raises pitch
and so forth, but don't understand how these functions would be called
dynamically from features.conf.
You'd just create the application_map as documented in features.conf and
then apply the PITCH_SHIFT() function to whichever channel you want.
Untested, but should look something like:
pitch_up_them => 3*,peer/both,Set(PITCH_SHIFT(tx)=high)
