Hi,
From my experiences, bandwidth limiter is the most efficient way to reduce latency for my SIP phone. I have a slow 4.3 Mbit/s DL and 1 Mbit/s UL connection. Limiting DL to 3Mbit/s and upload to 0.7 Mbit/s for the whole range of available IP addresses, make my phone calls perfectly smooth. Unfortunately, after upgrading to 380.68_4 it seems that bandwidth limiter didn't work anymore.
In fact, it seems that the whole QOS configuration is reset if you change something which is linked to Trend Micros's DPI engine (advanced stats, AI protection, Apps analysis, ...). If you don that, you have to re-enter from scratch the bandwidth limiter configuration to make it work again :
1. turn off the "Enable QOS" switch
2. turn it on again
3. re-enter the client rule (for me it is: 192.168.1.2-199 | 3 | 0.7)
4. Click on "Apply"
This re-enables QOS and it is rebooting persistent.
Hope this can help.
