No. Transformations work in route script only. > - Will providing PVs in a dynamic string work with all functions, even for > those currently not supporting string concatenation?

That's most functions nowadays, but not some of the older ones from OpenSER <= 1.2. > If yes, I assume this will only work for PVs, as preprocessor defined > strings won't be substituted if the parser finds their labels enclosed in > quotes. In other words, the following won't work: > append_hf_value("P-Asserted-Identity", "<$var(new_pai);SOME_DEF>"); It will if SOME_DEF was defined via #!subst. > - I assumed this would work in the first example, but maybe I should ask > explicitly.

But it will work if it's a #!subst, as is also the case if it appears in strong constants. #!subst "/SOME_PREPROC_DEF/xyz/" $var(x) = 'abc123'; xlog("L_INFO", "$_s($ru;SOME_PREPROC_DEF=$var(x))\n"); May 02 13:57:42 allegro-1.evaristesys.com /usr/local/sbin/kamailio[13998]: INFO: <script>: sip:s@10.150.20.2;xyz=abc123 -- Alex -- 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 (SER) - Users Mailing List sr-users@lists.kamailio.org https://lists.kamailio.org/cgi-bin/mailman/listinfo/sr-users
