Re: [sr-dev] Set arbitrary destination port for outgoing request/reply

Hello, for sip request, just set the $du to the address you want to send, I guess the port you know, doesn't really has to be randomly generated by Kamailio -- however, if yes, then there is a variable that should help, iirc it is named $RANDOM, but you can check the pv cookbook in the wiki or the cfgutils module. For sip replies, try also with $du, although it might not work and then something needs to be coded in the core to make it work -- I expect to be something trivial to check if $du is set for the reply and use that for sending out instead of via address. There is likely even now a chance to work with onsend_route enabled for replies (see global parameters in the core cookbook) where you can use send_data() function with the first parameter being the address where you want to send it and the second $snd(buf), then do drop() not to let response be sent again by core.

I am working on a sec-agree extension implementation for Kamailio and after negotiating the IPSec tunnel parameters I need to redirect the messages to the new port number. I checked the code and looks like the destination port is determined mainly by the VIA headers, which doesn't work for me. Is it possible to achieve this without messing up with the core?
