Woah, lots of pages in this thread..

Anyway, after the upgrade I've noticed that my SIP account doesn't seem to work anymore. It registers fine, but on my first call attempt the recipient answered the phone, but no sound came through in either direction. On all following attempts the N900 appears to be initiating a call (it says "Calling"), but just hangs there until I press End. A tcpdump shows that the N900 doesn't send any call initiation at all. It's not a problem with neither ISP nor VoIP provider (musimi.dk if you're curious), because my Nokia E51 works fine on the same account and network.

Have others experienced this problem? It's a bit frustrating, because I rely on the SIP functionality to stay in touch with family.

-- edit: Nevermind. The problem went away after a reboot. SIP works like a charm again
