[SFLphone] Call by SIP URL

[Esben Stien]

I'm trying to make an unregistered call with sflphone, using a SIP URL,
with a specified port and it doesn't seem to like that.

The URL I'm trying to dial is: 

sip:con at esben-stien.name:5080

It just won't complete the call and just displays a red cross. Removing
the ":5080" part, enables it to dial the URL. 

I'm using sflphone-0.9.6.

Any pointers as to what I can try?.
