[Users] dialog module configuration question

[Bogdan-Andrei Iancu]

Hi Michael,

as you give you the same answer as to Andy :) :

"To be honest I'm not fan of complicating my life just to support broken 
stuff :)....doing dialog matching in traditional way (without using RR 
stuff) is very costly and since complete, un-altered RR mirroring is 
mandatory by RFC3261, I see no point of doing it different. "

I think the best approach is to force the UAC vendors to align to the 
SIP specifications.

regards,
bogdan
