Re: [reSIProcate] outbound message decorators

[Byron Campen <bcampen@xxxxxxxxxxxx>]

	I think that the decorators _are_ being executed multiple times for  
stack-level retransmissions here. This is a bug (after all, the point  
of the stack is to abstract away the SIP retransmission mechanism,  
and the decorator is application code). I'll look into fixing this.

Best regards,
Byron Campen
