Echo After Return From Hold - Softphone

[DrainBamaged]

Server: Windows 2012R2 - 3CX v16.0.3.676 Enterprise
Softphone (Latest version - Local provision)
Client: W10 Enterprise 1903 (Fully patched)
Headset: Jabra BIZ2300 USB

User complaining that she hears an echo after bringing a call back from hold. She puts a call on hold (or is put on hold by the caller) and when the call continues an echo is heard when she speaks. Person who called does not hear anything untoward. Does not happen every time. Best way to replicate is for caller and callee to both put call on hold. Confirmed this on her machine and my test PC.

Tried:
Echo cancellation ON in Audio Settings.
Lowered volume on headset. This helps, but echo still audible.
Turned off "PBX Delivers audio"

Not sure where to go next.

Hi,

If the user changes headset to perhaps another model, does the issue go away?

If you capture the call and hear the audio is there an echo of your user? If the other side does not hear echo it may be something that is happening only on the headset/pc itself, before the audio reaches the 3CX client.
