    Ok question,

    When you get called the phone rings, the caller can hear you but you cannot hear the caller?

    Now when you call have a look at the status for you incomming line you will see (999)?

    Try to change your RFC protocol to RFC2543 you do this on the phone on which you have no voice comming in some phone allow you to change that.

    When Digital Receptionist (Enable)
    Outside PSTN User dial in through FXO GW.
    Caller can't hear called (extension user) and called(extension user) can't hear Caller too.

    So the bottom line you cannot have a conversation? (Talking on the phone is over rated anyway I think LOL).

    Looks like the initiation is getting through but the SIP stuff is not. Is there anything showing up in your 3CX log?

    Eg when you PSTN line does that go orange (denoting that a call is comming in?).

    See to me it sounds like a Codec thingy an that might relate to a Firewall not allowing RTC traffic through. Ports 10000 to 20000 need to be open for RTC.

    Just to confirm your VoIP out is working OK is it?

    Hello Dan Hriscanu,

    My 3cx phone system used version 10. And after completed for setup I tried to add PSTN gateway that use with Audiocode MP-114 2xFXO 2xFXS. Now my 3cx phone system work with that Audio code. Everything is ok, I can call to mobile phone and mobile phone can call back and pick up from 3cx but the problem is only 3cx phone can hear caller from mobile phone but mobile phone can not hear.

    Big thanks before hand,

    Hi,

    More details means, server activity log, configuration information, whireshark captures. There could be a lot of configuration issues for your problem. You have to be more specific. Try to look in Server activity log and see what is happening. Post them here if you find something relevant.
