1.3.2 w/o Tunnel Can't Hang up

[Bruce T]

Phone is Sprint HTC EVO.
Version 1.3.1 did not work.
Version 1.3.2 w/tunnel works fine.
Version 1.3.2 registers,
I can call an extension,
after leaving message on voicemail,
the Red Hang Button up does not work.
after 1 minute or so it automatically disconnects.
