Re: [SR-Users] Wrong "To" header in CANCEL, when "To" has been rewritten by uac_replace_to() in branch route

Hello, I know it was already discussed, that not recommended to modify "To" header and no routing should ever be done on "To". But as long as thereare carriers that do it, we need full support for this manipulation for all messages in the call flow. Ifound in list a fewmails with the same problem of wrong header "To" in CANCEL after "To" rewriting. And one solution from *Vitaliy**Aleksandrov :* *http://lists.sip-router.org/pipermail/sr-dev/2012-October/016657.html* "Kamailio builds "To" header from the received INVITE. Patch to fix it: --- ./kamailio-3.2.3/modules/tm/t_cancel.c 2012-08-22 10:39:21.000000000 +0300 +++ ./kamailio-3.2.3-fixed/modules/tm/t_cancel.c 2012-10-01 18:25:57.000000000 +0300 @@ -284,7 +284,7 @@ if (cfg_get(tm, tm_cfg, reparse_invite)) { /* build the CANCEL from the INVITE which was sent out */ cancel = build_local_reparse(t, branch, &len, CANCEL, CANCEL_LEN, - &t->to + NULL #ifdef CANCEL_REASON_SUPPORT , reason #endif /* CANCEL_REASON_SUPPORT */" We use header "To" manipulation in branch route (after failure route) and this patch solved our problem with "To" in CANCEL. But a patch is not committed. *Is it possible to commit this solution?* Thank you, Julia _______________________________________________ SIP Express Router (SER) and Kamailio (OpenSER) - sr-users mailing list sr-users(a)lists.sip-router.org http://lists.sip-router.org/cgi-bin/mailman/listinfo/sr-users
