Traffic Shaping AND fq_codel in 2.4.4

[XabiX]

Hello,

I have recently discovered the threads about CoDel and have implemented it on top of the traffic shaping I had already to prioritize my Voice traffic. Unfortunately the issue I have is that my WAN is built with OpenMTCProuter for WAN aggregation and includes 2 ADSL and 2 4G lines which creates a lot of jitter and impact the quality of the calls.
But it's getting better now :)

Here is what I have

1/ If I am correct, I am wrong and there should be only the entries for OUT Connections. Therefore I can delete line 7

2/ Line 4 and 5 should be duplicated to have IN and OUT directions? Initially I had 2 lines to put the traffic in the qVoIP queue but now that I have added Codel through WANUploadQ and WANDownloadQ then each line should be devided in 2 to put it in IN and OUT with a defaultGW.

3/ Does CoDel make sense for UDP traffic?

4/ In general my issue was more around delay and bandwidth therefore I was wondering if it makes still sense to keep the traffic shapping. I can always disable the QVoIP entries or put a different default GW to directly send this traffic to one ADSL. Any recommendation or experience here?

Thank you very much
