So, with this i solve the issue on main office. But what about the two remote? they are so little that they will not let me place another * box there. The phones will be SIP and they are like this INTERNET--PIX--LAN(machines and sip phones). The pixes in those two offices have an ipsec tunnel with the main office via internet. I was thinking of placing the asterisk with a public IP so the remote phones can NAT outside to the public asterisk located in the main office.
