Outgoing call bi-directional, Incoming call one-way

[wiles01]

Hello,

Started having this issue it seems when our company upgraded to V15.

If I call out, the communication is fine, bi-directional. I can hear them, they can hear me.

If a caller calls me, they can hear me talking, but I cannot hear them.

I have tried adjusting my firewall settings for inbound traffic up to and including turning off my firewall all the way, no effect.

Did you expand your firewall ports?

(You do not say if the PBX is local or remote)

It's weird that one direction is working and the other leg is not.
So many variables here.

Have you tested same scenario using an IP Phone?

PBX is remote (Ohio). I am currently in Alabama.

I have set my router for port forwarding on all the items listed in the sticky FAQ.

New wrinkle... sometimes, if I yell into my iphone, I can hear it through the earpiece on my headset. It's like the audio is being limited or blocked from the incoming call.

Outgoing calls, I can speak in a normal voice and both bi-direction communication is fine.

Incoming calls, either I can't hear at all, or I have to yell into the phone for it to break through. Could it be some kind of noise cancellation setting?
