I have successfully setup VOIP/SIP calls on my brand new N900. I can make outgoing calls with the dial pad as long as I set the calls to SIP first. This is not a problem.

The problem is if I want to call someone from my contact list using SIP. if I select someone from the contact list, it always defaults to cellular -- I have no way to change it to SIP. How do i make sip calls to someone in my contact list without have to punch in the actual number?
