[Serusers] Cyclic Attack ??

[Kannaiyan Natesan]

Will Ser handle Cyclic attacks ?

I.

If I have two domains A  & B,

   When A requests a call forwards to B, & B forwards to A.
   Will Ser be able to prevent this cyclic attack? or how to mange this?

II.

 Asume we have two domains,  A & B Pointed to a single ser server.
 If I create a user in Domain A will the ser validate only for domain A
only.
 I could not find any domain information in the subscriber table.

Anyone help me pls.
