Ring Group missed calls

[rjb]

I think there are several ways to accomplish this. As indicated above, the most obvious way to do this is at the VoIP service provider level, but you could also:
a) add a third option to enable / disable list called something like database and then point each phone to a mySQL database where the phones add entries when calls come in and read the list when asked to display the phone list. Then everyone is reading from the same list.
b) make it so that one phone in the Ring Group is the "master". Each of the other phones in the ring group update the "missed call log" on that phone.

The advantages of the two options mentioned above is that these solutions are VoIP provider agnostic.
