Do you know of any place where I can search for known issues in Blink?
Besides Google, I mean. Searchig for "blink" gives too many unrelated
results. How does the project keep track of bugs?

I'm not familiar with RFC 3581 (yet), but did you mean, "should be used"
by the SIP server? Or client?

So, if I parse this correctly, the SIP server needs to do some magic?
Blink is sending this wrong address in the first packet, so the SIP server
should ignore it and send replies to the "Contact" address anyway?
