[reSIProcate] Multiple non-invite client transactions

Late response, but this has confused me and I want to make sure the 
record (and my
understanding) is correct.

I _think_ what Jason's saying is that ->DUM<- will allow only one 
outstanding non-INVITE
client transaction on a given dialog. DUM will, I believe, allow 
parallel non-INVITE client
transactions on different dialogs. If you're using the stack directly, 
it won't put this kind of
limitation on you.

I'm only begrudgingly comfortable with this limitation in DUM (if I 
understand it correctly).
The use cases that people had in mind when they made that decision were 
primarily
wrapped around INVITE related dialogs. I'm not as comfortable with 
putting this limit
on NOTIFYs, but for expediency am going with the flow.
