Description

Depending on who I am calling: the call is crystal clear or it is like metallic / robot and very difficult to listen correctly.
This is very reproducible as for some mobile numbers dialed it is or always crystal clear or always metallic.

My Replicant installation (4.2 or 6.0) is stock for everything expect Bluetooth (as I really need it), on Bluetooth it is working well every-time.
I confirmed it is not due to Bluetooth bloob as my 6.0 Replicant is without it.
I confirmed it is not a faulty hardware / speaker on my phone as going back to stock ROM is working well.

I had some discussion on IRC and someone advice me to temporarily disable 3G networks and force 2G and the problem gone.
It confirms that calls passing trough 3G have an issue, is there a way to disable this function somewhere in advanced settings? I need to keep 3G as 2G is too slow when I am using the phone for mobile data. (and switching to 2G is not an option when someone is calling me I don't have time to do it)
