[VoiceOps] Customer Premise Firewall/Router Recommendations

-1 for Sonicwall.  Been fighting issues with 1-1 NATs with separate signaling server and media server setups.  The Sonicwall SIP ALG doesn't take into account the 1-1 NAT for the media server and sets the external IP in the SDP header to the signaling server.  However, a Cisco 3725 (and most other IOS based routers) worked out of the box with this type of setup.
