FXO - SBC

[sandyhardi]

Hello There!
Need Help!

We have connected FXO and FXS to SBC and all these devices are on Prem.
We have 3CX on cloud and have registered these devices succesfully. FXS and FXO go thru SBC for reg.

We are able to receive incomming calls. but unable to make outgoing calls. Is there any special changes or configuration we need to check?
We can see from the FXO that the channel is being used for outbound.

attaching the Outbound rule we created as well as the wireshark of the outbound call.

for this test we used: 19997 extension to call out to +6588963959 and 6588963959.

The only supported scenario is when FXO is running on the same network as 3CX.

The only supported scenario is when FXO is running on the same network as 3CX.

It can be external and connected via VPN.

It can be external and connected via VPN.

yes

edit: ... maybe. It depends on the FXO and the VPN connection.
