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.

OK, the log looks pretty good, we have consistent callreferences
throughout
the life of each call.

I see one issue, but I am not sure it explains this behaviour.  The first
line of the log:
chan_skinny.c:1293 find_subchannel_by_instance_reference:  Could not find
subchannel with reference '0' on '5500'

The wireless phones cannot dial from an offhook state, so we have not
yet created a subchannel.  I would expect this message to happen EVERY
time a wireless phone places a call, or any time a wired phone places
a call from the onhook state (speeddial/vm/redial)

This hints at the possibility that we are not cleaning up sub channels
properly.  Looking at the code, I think this is very likely.

I have two more tests that may help narrow this down.

1.  Place a call-
    What is displayed after you press 'Send'?
    What is displayed when the far end answers?
    What is displayed after you hangup?

2.  Your logs show that you are hanging up the cal on the originating 
    7921, what happens if the far end hangs up?  Can you then place a 
    second call?
