Has anyone actually managed to get the N91 working as a SIP phone with Asterisk? Following instructions for the E61 didn't work - the phone registers with Asterisk just fine, but Asterisk logs an "Unsupported Media Type" error when someone tries to call it - and there seems to be no way to even select outgoing calls to go through VOIP instead of 3G or whatever my normal phone provider has.
N91 and VOIP through Asterisk
I have the same problem with nokia n91 and nortel BCM :con?
