I am having problem getting the FVS338 to work. I have the latestet firmware 3.0.5-24 on the Netgear and Latest IP Office Firware on the 5610IP Phone. I can not even pass the IKE Phase 1....is there a firmware version for the FVS338 that with work with the VPN Phones? I have done Kentrox and Sonicwalls without any issues.
