Thanks for the feedback !
What did you do finally, change the weight or disable DTX for AMR calls ?
As i said, I would strongly recommend the 2nd solution.
I am surprised those parameters are affecting your congestion. I thought it was just a Quality Issue ?
The average congestion of your network is rather high, but I’m glad it decreased a little. What is your RTCH_Duration_Average ?
To decrease congestion, have you activated EN_FDR and EN_DR in all your cells ? You could tune the FDR parameters, they offer a very effective way to distribute traffic with neighbour cells. However, you told me the traffic is already shared…
So now you could increase the HR usage…
