[Serusers] Preregistering a sip address?

Hi all! I have just started using the SIP Express Router and I am looking for a way to have a user preregistered when the router starts. Is there any way to configure that user1 should be registered by default at an IP address without needing to send the registration? I guess it will have to do with messing a bit with the routing engine, but I don't dare to touch it so far and I don't know how to do it. Any help would be very much appreciated! Thanks very much for any help! /Nacho --- ,,, (o o) --ooO--(_)---Ooo----------- Three may keep a secret, if two of them are dead.- --oo0--------0oo-----------
