Hi Laqoore, For a start: /mhomed=1/ /listen=*udp*:yourip:5060/ /listen=*tcp*:yourip:5060/ On Thu, Oct 4, 2018 at 12:06 PM M K &lt;laqoore(a)outlook.com <mailto:laqoore@outlook.com>> wrote: Hi, I'm struggling with the configuration to use Kamailio as TCP UDP proxy: [SIP Client] <-(TCP)-> [Proxy] <-(UDP)-> [SIP Server] should be the setup. I only have one client and one SIP server.   How do I get Kamailio configured as a proxy so that translation between TCP and UDP works (and vice versa)? I have not yet found any documentation and examples that have caused messages to arrive at my SIP server. I think I've been on the wrong track so far and I'm looking forward to any help.   Thank you in advance, Laqoore   _______________________________________________ Kamailio (SER) - Users Mailing List sr-users(a)lists.kamailio.org <mailto:sr-users@lists.kamailio.org> https://lists.kamailio.org/cgi-bin/mailman/listinfo/sr-users _______________________________________________ Kamailio (SER) - Users Mailing List sr-users(a)lists.kamailio.org https://lists.kamailio.org/cgi-bin/mailman/listinfo/sr-users
