    Outgoing calls (From 3CX extentions to CME extensions) are working over Generic SIP Trunk (Type of Authentication -> 'Do not require - IP Based'). But incoming calls from CME are rejected with 'SIP/2.0 407 Proxy Authentication Required'.

    In Generic SIP Trunk > Call Options both inbound and outbound calls are allowed by default.

    3CX version 15.0.0
