    Hello
    I configured an yeastar TG200 in order to route calls over the gsm network. In order to make this happen i followed the guidelines which tells that the authentication method should be set to "Do not require - IP Based"
    Outbound calls are working flawless but inbound the pbx throws a 407

    SIP/2.0 100 Trying
    Via: SIP/2.0/UDP 192.168.150.232:5060;branch=z9hG4bK1a60db9a;rport=5060
    To: <sip:0xxx@192.168.150.42:5060>
    From: "+316xxx" <sip:+31xxx@192.168.150.232>;tag=as1d49d203
    Call-ID: 34c324495355f34e2035bc276203be61@192.168.150.232

    User-Agent: 3CXPhoneSystem 15.5.9348.3 (9348)

    Based on the type of authentication i would not expect this.. Is there a way to work around this?

    In the meantime i found the solution :) The device needs to be configured as "Add sip trunk" instead of "Add gateway"
