Summary:                    Skinny to skinny calls one-way audio
Description: 
Version 76621 fixed the crashing of asterisk due to soft-key problems, but
introduced another problem.  

7921 -> 7921 phones the remote party could not hear any audio.  In version
76784, the 7921 that initiates the call hears no audio.  If a 7920 phone
calls a 7921/7920 phone, then both parties hear audio.

The find sub by reference is going to continue to be an issue. Some devices
do not send this information. I have a CCM dump of a 30VIP to a 7960 which
indicates the offhook message on a 7960 including some reference info and
the offhook message of the 30VIP not indicating any reference info.

Skinny needs to be changed to track its own reference info. The general
approach in the transfer patch is that chan_skinny tracks the reference
info, and if no reference info is provided by the device, it uses its own
reference info.

I have a feeling that the 7920/21 devices also don't send reference info,
but find_sub_by_reference just returns the first sub on the first line. Not
pretty, but for simple call structures (single line, single channel sort of
stuff) it should work.
