Problem:
Errors and call drops, since moving over to Windows 7 SP1 64bit from Windows XP SP3 32bit
Error: C++ R6025 - pure virtual function call
Drops: Users have two lines, an extension and an ICD extension, if a call is active on a extension when they get an ICD call and go to either hold the first caller or just answer the incoming, ICD call gets dropped. Sometimes phone just shuts down with a headset disconnected message and sometimes without a message.
Hardware:
Windows 7 SP1 computers
Logitech H340 (Happens with this headset or much more often with it. Oddly enough a different brand headset seems to encounter this issue 100 times less. Can cause more frequent if user, uses the answer button in a line.)
IPCommunicator 8.6.2 (8.6.3 can't log onto a phone using Extension Mobility Service. Nothing under services.)
Cisco Unified CM Administration, System version 8.5.1.13900-5
Cisco Unified CCX Administration, System version 8.5.1.11002-22
I'm hoping that someone else has already found a work around. Please help if you can.
