I have thew same problem. Ui tried with dyn dns in the externip field in sip.conf but I think the Asterisk does not allow this. Unfortunally I have every day a new ip. Maybe I can write a script witch takes my actual ip from externat and put it into the externip field. Maybe this solves the problem.
