when ooma is in the process of updating firmware maybe it would be possible to have a unique sequence of flashes similar to that of when the telo boots up (lower right set of buttons flash in sequence) that is recognizable so consumers know not to interrupt the process-- maybe even a pre-recorded msg telling you this is happening when you pick up the handset (instead of the fast busy signal).
** also, a text msg alert to say Telo firmware update is (about to be) in progress (at least 1 min before it begins).
