Re: [Sip] Outbound Issues: slides 3 and 4

Hi Bob,

How about if we said something like

If the UA did not learn the outbound proxy set thru auto-config or  
discovery mechanisms, then it MUST do an OPTIONS message first and  
check for a sip-stun option tag. (clearly more wording needed but you  
know what I mean)

Would that work for you? I suspect it would work for most people. I'd  
certainly be in favor of that. I suspect for proxies with millions of  
users, they will use auto-config so this will not slow them down and  
for proxies with UA with manual config, it will not be enough UA to  
cause a huge performance impact. I don't know why I did not think  of  
this before.
