Hi List I'm looking into the perl module. Am I right, that I can not add or remove HF from an app_perl subroutine? I would need to pass an AVP from perl to tell Kamailio what to do? Goal is an attempt to re-build part of the topos functionality in perl but only handling RR and Route Header only on one leg, not on both. -- Mit freundlichen Grüssen -Benoît Panizzon- @ HomeOffice und normal erreichbar -- I m p r o W a r e A G - Leiter Commerce Kunden ______________________________________________________ Zurlindenstrasse 29 Tel +41 61 826 93 00 CH-4133 Pratteln Fax +41 61 826 93 01 Schweiz Web http://www.imp.ch ______________________________________________________
