Hi Bogdan, The UAC -> P1 -> P2 scenario was something I was hoping to avoid because it puts a reliance on P1 being up, even though its really not needed. I've been trying to play with DNS SRV, and returning some sort of failure code so that a UAC would at least move to the next server with the same priority, but alas it doesn't appear that DNS SRV is a well implemented thing in UACs.
Thanks. -- James On Fri, Feb 4, 2011 at 5:18 AM, Bogdan-Andrei Iancu <bog...@opensips.org> wrote: > Hi James, > > it is a know issue that most of UAC do not properly implement 3xx for > REGISTER requests...
