Hi,

Generally, incoming traffic (http/mail/sip/vpn/etc) can easily spread
with the random functions with iptables. 
Perhaps also have a look at:
http://www.linuxvirtualserver.org/VS-NAT.html 


But i feel that might not work in this case, if all your
trunk-connections are already up-and-running.

If so, you might contemplate an alternative approach.
It sounds that you want to do the load balancing trick upon the
application layer (eg. within asterisk)

Perhaps it is possible to do the L.B. at the O.S. or network level, and
let all trunks appear to asterisk to one single trunk.
