There's facing an one way audio issue.

Therea are two LANs. PBX located networks ip phones are normally (two way audio call is successful).

But another subnet, which is not located pbx's ip phones are facing one way audio call issue.

A network diagram would be really helpful as would the version/JHF level.

Keep in mind that you need to open the UDP high port range defined in the PBX, in both directions, between the networks your phones are in.
The audio stream is a connection directly between both phones having a call. The audio does not run over the PBX.
