Hi Leejor and members,

In the packet "SIP INVITE" of the ISP with format: sip:Caller-ID@IP:5060;transport=udp |

In the packet "SIP INVITE" of my system have format: sip:Caller-ID@IP |

I want to insert parameter sip field: transport=udp to SIP INVITE but I can't,

I follow link: https://www.3cx.com/community/threads/how-to-add-transport-udp-in-request-invite-sip.65850/, insert transport-udp.IP to Registrar/Server/Gateway Hostname or IP, else SIP INVITE my system have format: sip:Caller-ID@transport-udp.IP --> FAIL

Pls help me,

Thank so much
