vr900v telephone book, small, but real bug
If you receive an international call from the UK, for example, the call log shows the number as +44....
If you copy and paste the number into the vr900v's telephone book, the web page says, you can only type numbers (not a "+") into the telephone book.
You can, of course, type in 0044..., but then when this number calls you, it announces itself as +44... and the vr900v does not match the number. It does not display on the caller ID (clid) on your phone.
I can see that this is not a serious problem. On the other side, one can imagine that it is not a huge programming task to change the number storage code or matching code.
