Hi Nick, I think it might be worthwhile to ask why you want to provide these arguments to t_relay(), even though it can take them.
There is a common and understandable misconception among new users that specifying these arguments is the way to tell Kamailio the destination to which a message should be relayed. In fact, it’s not the canonical way it is done. t_relay() consumes the domain part of the request URI ($ru): $ru = “sip:" + $rU + "@10.0.1.1:5060”; # or $rd = “10.0.1.1”; If the domain in the RURI is different than the desired network destination, the “destination URI” can be used to override this: https://www.kamailio.org/wiki/cookbooks/5.5.x/pseudovariables#du_-_destination_uri $du = “sip:10.0.1.1:5060”; These values can of course be constructed from variables as well. So, it is likely the case that you don’t need to call t_relay() with arguments at all. :-) — Alex > On Jan 5, 2022, at 3:21 AM, Nick J <[email protected]> wrote: > > Hi all, > I've been banging my head on the table with this one and hoping someone has > some insight here. > I'm trying to use a variable as the host & port input in t_relay() - > t_relay(host, port) > > This works fine if statically set: > t_relay("10.0.1.1", "5060"); > > But if I change the host or the port to a variable like this: > $avp(destip) = "10.0.1.1"; > $avp(dstport) = "5060"; > t_relay($avp(destip), $avp(dstport)); > > Then Kamailio fails to start, calling out the t_relay line: > kamailio: CRITICAL: <core> [core/cfg.y:3686]: yyerror_at(): parse error in > config file /etc/kamailio/kamailio-routelogic.cfg, line 62, column 35: bad > command > > I get the same behavior with pseudovariables and vars as well: > $var(destip) = "10.0.1.1"; > $var(dstport) = "5060"; > t_relay($var(destip), $var(dstport)) > > Any tips or pointers would be much appreciated. > Thanks! > > Nick > __________________________________________________________ > Kamailio - Users Mailing List - Non Commercial Discussions > * [email protected] > Important: keep the mailing list in the recipients, do not reply only to the > sender! > Edit mailing list options or unsubscribe: > * https://lists.kamailio.org/cgi-bin/mailman/listinfo/sr-users -- Alex Balashov | Principal | Evariste Systems LLC Tel: +1-706-510-6800 / +1-800-250-5920 (toll-free) Web: http://www.evaristesys.com/, http://www.csrpswitch.com/ __________________________________________________________ Kamailio - Users Mailing List - Non Commercial Discussions * [email protected] Important: keep the mailing list in the recipients, do not reply only to the sender!
