Have recently trialed a Fortiwifi 40C for a client. They are a SMB, 20 users, (20 computers/20 VOIP handsets). Replaced existing Airport extreme (all mac environment) , with the 40C. Airport Extreme wasn;t providing QOS on VOIP.
VOIP calls with the 40c were clearer, but wireless speed was terrible, 40C memory @ 80% CPU @ 30-100%. Updated latest patch, checked all maps and policies, all ok. Disabled UTM. Still poor performance.
Soooo I need recommendations for a good wireless router that can open ports for SIP 5060, have wired and wireless clients on same subnet (40c couldn't, well not without putting more load on), handle VOIP, etc. About 20 users on line also doing general web useage. 20/2 adsl bonded connection as well BTW.
