Ilie, No, RC assignment is no different than M3UA: it only needs to uniquely identify a traffic flow within an association. When there is only one traffic flow per association, RC can be trivial (i.e. 0). Nevertheless, the sender of ASP Active need not include RC, ASP Active Ack has a mandatory RC value which both peers can populate every subsequent message requiring an RC. --brian Ilie Glib wrote: (Tue, 20 Dec 2005 14:19:18) > Brian > > According to SUA RFC the RC value shall be unique (at least) within a > Signalling Process, thus one RC value per "signalling relation" is > needed.
