I understand your position, but there are some another problems with this approach. In real world, you can't predict for all cases whether your outgoing leg will pass the same servers as incoming leg. If you maintain code of border system (e.g. between Internet and local network) and it's improbable that this code will be used for other setup style, you can do this. But in general it's quite danger. I don't suppose you're writing stack for such local task; likely it's universal one. If so, better create new tag and avoid any chance for having identical leg ID. > Thanks a lot for your reply. not at all :) -- Valentin Nechayev PortaOne Inc., Software Engineer mailto:[EMAIL PROTECTED] _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
