Hello, there is an alternative where you can use a combination of xavps and corex module function via_use_xavp_fields() -- see: * https://www.kamailio.org/wiki/cookbooks/5.3.x/core#xavp_via_fields I think I looked at some point at set_advertised_address() from core to make it accept variables, but its current form does some pre-compilation at startup, keeping back references that are used at runtime, so it was not an easy update. But we can add new functions to set those xavps and the internal flag, if people find it simpler. The old function can stay for those that want to work with static values for a bit of more speed.

For example, set_advertised_address("$var(someaddress)") results in a VIA of string $var(someaddress), instead of var's value. https://www.kamailio.org/wiki/cookbooks/5.3.x/core#set_advertised_address kamailio 5.3.2 (x86_64/linux) 0bed10 Cheers. --Sergiu _______________________________________________ Kamailio (SER) - Users Mailing Listsr-users@lists.kamailio.orghttps://lists.kamailio.org/cgi-bin/mailman/listinfo/sr-users -- Daniel-Constantin Mierla -- www.asipto.comwww.twitter.com/miconda -- www.linkedin.com/in/miconda _______________________________________________
