Summary:                    Playback(<file>|noanswer) and in-band info are not
working with chan_skinny
Description: 
tried to playback with noanswer option, it works with chan_sip or chan_iax,
but not with chan_skinny, also other inband info messages from telco are
not possible with chan_skinny.
eg.: when calling to unavailable gsm phone and telco operator says "person
you are calling isn't available" chan_skinny plays normal ringing tone,
chan_sip and chan_iax plays this in-band messages fine.
tested with ci$co 7920.

Added a patch based on comments and discussions (earlyrtp.diff).

Include an option in skinny.conf to enable early RTP, defaults to early
RTP. Basically, if the device is set to earlyrtp, skinny_indicate does not
send a transmit_tone to the device, but return -1 to asterisk which tells
asterisk to do inband (thanks to qwell and russellb).

The structure is horrible because I didn't want to change the order that
packets are sent to the device so we have to if statements for each
indicate. Could clean up if skinny devices are happy to receive the
transmit_tone after the other stuff.

Works for me (tones are obviously different to the device tones) on
30VIPs. Haven't tried a playback. Also, haven't change sub->outgoing to
sub->incoming.
