[OpenSER-Users] Call Forking

[Peter P GMX]

Does anyone have an idea how OpenSER behaves in terms of call forking?

That means:
- A sip client A registers at OpenSER from IP adress A,
- then another SIP client B registers at OpenSER from IP adress B with 
the same credentials while A ist still registered.

Question 1:
- does OpenSER allow both clients to register with the same credentials?

Question 2:
-  can this be switched on/off somewhere?

Question 3:
-  in case it works, can an incoming call being routed to A and B 
simulaneously?

Thanks for your help
Peter
