i am designing a new network with the ASA 5505, please find attached file to see the map.

is the ASA 5505 able to route VoIP packets destined to SIP server 2 and 3 simultanously from SIP server 1 according to the MAP ??

If i configure a real IP for the SIP server 1, would the ASA 5505 still protect from security issues ?

any other advice concerning the the design ?
