hi list, I want copy all sip headers between two legs, but I don't obtain a good result. example: P-Asserted-identity, P-Preferred-Identity, Diversion, etc ... aren't copied for leg B. I have found "sip_copy_custom_headers=true" but it's just for X-Header. Actually, I use this code below, but it is not easy :( *<condition field="${sip_P-Asserted-Identity}" expression="\+(\d+)" break="never"> <action application="log" data="LOG Modifying PAI sip:+33xxxxxxxxx@DOMAIN" /> <action application="export" data="sip_h_P-Asserted-Identity=<sip:+$1@3008LI.hexavoip.fr <1@3008LI.hexavoip.fr>>" />* Have you an idea for me ?
