The reason that I would like to either disable the Acceleration or either whitelist the below mentioned traffic is the following.
We have panasonic VoIP devices that reside on a VOICE VLAN and they communicate periodically, with the PBX which resides on another VLAN. With FW acceleration enabled which is the default setting, the phones every now and then restart. With FW acceleration disabled, the phones behave normally ie no restart occurs.
So , ideally I would like to whitelist the traffic, but i am not able to do so due to the fact that my SMS is cloud based. Therefore, I reside on completely disabling the FW acceleration.
