That might work. Just have to make sure that existing parameters in the contact without <> have to be moved outside the > because they are header parameters (according to rfc3261 section 20, last paragraph). If i understood correctly the following cases must be supported: These go wrong at the moment: Contact: sip:192.168.1.10:5678 should become Contact: <sip:192.168.1.10:5678;alias=X> Contact: sip:192.168.1.10:5678;header-param should become Contact: <sip:192.168.1.10:5678;alias=X>header-param These are already correctly supported: Contact: <sip:192.168.1.10:5678> should become Contact: <sip:192.168.1.10:5678;alias=X> Contact: <sip:192.168.1.10:5678;uri-param> should become Contact: <sip:192.168.1.10:5678;alias=X;uri-param> Contact: <sip:192.168.1.10:5678>;header-param should become Contact: <sip:192.168.1.10:5678;alias=X>header-param Contact: <sip:192.168.1.10:5678;uri-param>;header-param should become Contact: <sip:192.168.1.10:5678;alias=X;uri-param>header-param -- Greetings, Alex Hermann _______________________________________________ sr-dev mailing list [email protected] http://lists.sip-router.org/cgi-bin/mailman/listinfo/sr-dev
