Just added a new bug to my list, that I have noticed recently and nearly cost me very dearly...

I'm currently traveling in the Far East and was talking to someone in continental Europe over SIP (VoIP) with a UK N900 when that call got dropped. I instinctively used the call log to redial my contact, expecting the phone to use the same channel. This isn't the case: for calls initiated to saved contacts, the phone appears to always redial as a cell call. If you dial the call using the numeric keypad and redial it from the calls log, it does go back over SIP.

Fortunately, I noticed the shenanigan before it was too late - cost of the bug for 51 secs (in that instance): £1.98. This could easily have been £50 or more...

The bug is here - check it out and vote for it if you ever use the SIP integration on the N900...
