Audio output

[Oliver52111]

I set a 3CX on my office server. I can log in to the 3CX outside the office LAN. Besides, I can accept and decline the phone call from another user. However, there is no audio output for both endpoint users when making the phone call. Also, the phone call from 3cx to a mobile number using SIP failed neither. The SIP line works fine. Would you mind to show how to fix that?

What's your system version, what phones are you using, what method did you provision them (manual, STUN, LAN or SBC), and are you using a supported SIP provider?
Try enabling the option "PBX Delivers Audio" for both users under Management Console>Extensions>Options. To make an outbound call, make sure you have an appropriate outbound rule set up and that your SIP trunk credentials are correct. It's unclear to me whether or not outbound calls to other numbers other than mobiles work for you.

Thanks. I try the configure the PBX Delivers Audio but still not work.

The current version is 16. I test the call using my phone app and one browser app outside my office LAN. Both can be provisioned on the management console. They can call and receive calls but there is no audio output for both of them.

This sounds like it's not a 3CX issue. It might be a device or network issue.
One thing though, I find that sometimes when I install the 3CX app on mobile devices, the microphone is disabled by default. Have you double checked that the microphone on your smartphone app is enabled in settings? I know that in iOS you need to go to settings, 3CX and enable mic.
