[Asterisk-Users] Formatting in sip.conf...can you have 2 @ signs for register?

[John Todd]

<grrrr>  stupid top-posting confuses the hell out of these threads, 
but I'll continue the insanity.

I _swear_ I already brought this problem up and it got resolved, like 
1.5 years ago.  I explicitly remember talking with kram about a 
right-to-left parsing trick he implemented to solve this exact 
problem.  I don't feel like digging through my 3 gigs of mail to find 
it, but I _know_ we hit this a while ago, or something very similar. 
Why it's broken now, I haven't the slightest idea...
