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 plot thickens.  I went back to version 76708 without your latest patch.
 

There are two distinct problems, two which may be related. 

The first problem is callstate notification to the 7921.  When the 7921 is
on a call and the call is terminated, the 7921 earpiece emits whitenoise
for 5-10 seconds after the call is terminated.  If a call is made during
that period, no audio is heard on the 7921.  After that period, calls can
behave as you would normally expect.

The second problem is how the 7921 handles call Macros.  If the macro
contains Answer() the 7921 has audio issues.  It hoses up audio for 10
seconds to indefinitely (depending on the technology of the phone being
dialed) and really screws things up.  If you remove the Answer() portion of
the macro below, everything is OK with one exception -- the 7921 phone
doesn't indicate ringing on the line when making a call  -- the 7920 does
indicate ringing when making a call. 

exten => s,1,Set(TIMEOUT(absolute)=0)
exten => s,2,Answer()
exten => s,3,Wait(1)
exten => s,4,Dial(${ARG2}|20|tr)
exten => s,5,Voicemail(${ARG1},u)
exten => s,6,Hangup()
exten => s,105,Voicemail(${ARG1},b)
exten => s,106,Hangup()


I changed back to version 77112 with your patches.  And the removed
Answer() and the 7921 now indicates ringing.  The only problem that still
remains is the white noise period / no audio problem which lasts for 10 or
so seconds, then goes away.
