Re: [SR-Users] kamailio does DNS lookup of from host when using TCP

wrote:

Hello, apparently the register was replied, then it is another request (could be another register though). Can you load debugger module and set tis parameter cfgtrace to 1, redo the test and send the output? Also, it would be good to get the sip message for that case -- inside the request_route, add: xlog("received message: [[$rb]]\n"); Cheers, Daniel On 12/11/14 21:56, Vik Killa wrote: Hello, I'm wondering why kamailio will try doing a DNS lookup of the from host with a REGISTER packet when using TCP?
