Firmware version of Expansys EF81 clearance stock [BenQ-Siemens EF81 - 129660]


Just wanted to check on what the firmware version & phone bugs is on the Expansys EF81 clearance stock. I undertand that there were bugs in the original firmware (missed calls not being recorded, etc). Were these bug's ever cleared by firmware updates. I understand that BenQ Siemens went out of business shortly after this phone was released, so I understand that there is no formal support for this phone anymore, but I am not sure if firmware updates exist & whether is it possible to upgrade the firmware oneself.
