Hi, I’m a newbie and have been using these forums to configure the HT813 to work in the UK with 3CX. So far so good and I can make and receive calls using the FXS port both internal and external.
I can also receive calls via the FXO port from the PTSN, these are both routed to the FXS or other extensions by 3cx.
My problem is when I place an outbound call to the PTSN via the FXO port all that happens in the extension on the FXS port rings. I have searched the forums and 3cx and connect see this being reported. I’m at a loss to which settings should change to prevent the FXO port routing calls to the FXS port. These are outbound calls not inbound.
