i assumption you had a mistake for REGISTER. normal, the REGISTER didn't with any media description. and TRYING, RINGING will be sent after N900 received the INVITE.

i'm not familiar with sofia-sip, but as you said, "SOA" means SDP Offer/Answer Engine Module. you could check http://sofia-sip.sourceforge.net/ref...dex.html#index . then i agree with you that some parameter is incorrect.

i also hope you could post the detail of INVITE. so, we're could see what's parameters in that INVITE
