I have 2 planet vip882 gateways i am trying to test a peer to peer dialing test.I have connected the gatways to a switch using the WAN ports. I have two Planet VIP154T phones connected to the gateways through the LAN ports.i get a dial tone but when i try to call onr phone from the other i am timed out. I tried IP phone to IP phone testing trougth the switch its ok i can call, but when i connect to the gateways, i can not call, what am i doing wrong,i have set up the outbound dial plan on the gateways and i am using IP addresses to dial.

Can the planet VIP 882 be used as a proxy server as well.
