This addition lets you set artifical ringback on a channel
that is waiting for an originated call to be answered.

the syntax is 

<action application="set" data="ringback=[data]"/>

where data is either the full path to an audio file
or a teletone generation script..

syntax of teletone scripts


0-9,a-d,*,# (standard dtmf tones)

variables: c,r,d,v,>,<,+,w,l,L,%

c (channels)        - Sets the number of channels.
r (rate)            - Sets the sample rate.
d (duration)        - Sets the default tone duration.
v (volume)          - Sets the default volume.
> (decrease vol)    - factor to decrease volume by per frame (0 for even decrease across duration).
< (increase vol)    - factor to increase volume by per frame (0 for even increase across duration).
+ (step)            - factor to step by used by < and >.
w (wait)            - default silence after each tone.
l (loops)           - number of times to repeat each tone in the script.
L (LOOPS)           - number of times to repeat the the whole script.
% (manual tone)     - a generic tone specified by a duration, a wait and a list of frequencies.

standard tones can have custom duration per use with the () modifier
7(1000, 500) to generate DTMF 7 for 1 second then pause .5 seconds
