[cisco-voip] Answer: IP Communicator half Duplex

[Scott Voll]

This problem was self induced.



We repackage the IPC software for a no user intervention install.  In the
process we also add setting to the registry like the TFTP address.



Here is where the problem lies:



We also added about 60 registry settings that should NOT have been added.
Thus causing the issue.  These Registry settings were hold overs from the
2.x days.



We have created a Reg fix for our users to remove the 60 reg settings and
that seems to have fixed the issue.
