AAK FXO sidetone issues

Hello,

I have an AAK and call quality is great on voip calls, but I have multiple problems on my FXO channels.

When an FXO call is in progress I can hear myself speaking very loudly (sidetone). Sometimes I hear static in the sidetone.

I can hear the caller on the other end great, and like wise for them. This only happens for users on the AAK.

Any ideas? I can’t find a sidetone adjustment for zapata or zaptel.

Thanks,
Randy Q
