After putting in some thought. Please see below there following requests and if they are feasible within the next 1-2 years.
Integrate physically and logically a SIP aware ESBC style firewall for VoIP. Have 2 physically separated WAN and 4 LAN for this appliance. This appliance can only be activated with a License key. All the while there is still the entire other part of the Balance unit that stays the exact path you guys are pursuing currently. Again this is physically all on same Balance device or separate appliance.
Creating a cloud MOS server in InControl2, also only usable with license key. This is where we will connect our VoIP appliance side of the Balance to for MOS scoring and analysis.
Anyway this is my reincarnated 2 cents as I am waiting for the day for Peplink to announce such a feature. Let me know what you think about the feasibility of such a product.
