[Johansson Olle E]

Please check the full syntax for the register= option in sip.conf. You  
will find it in the section named OUTBOUND SIP REGISTRATIONS of  
sip.conf.samples in your source code distribution or here for release  
1.4:

register => user[:secret[:authuser]]@host[:port][/extension]
Reading documentation is a good thing (TM).
