Im' currently implementing SIP URI discovery using Bonjour (mDNS-SD)
as per draft http://tools.ietf.org/html/draft-lee-sip-dns-sd-uri-03

So, does this header look right? From: "test"
<sip:[email protected]:5844;transport=tcp>

According to the SIP grammar it is, but I'd like to hear some thoughts on it.
