Hello,

I am working on a BLF (Busy Lamp Field, dialog presence) integration using Kamailio. I am not sure how certain settings can be used on a single generic (any phone) Kamailio instance. * https://www.kamailio.org/docs/modules/devel/modules/presence_dialoginfo.html... "If the phone does not support this, you can activate this parameter." modparam("presence_dialoginfo", "force_single_dialog", 1) * https://kamailio.org/docs/modules/devel/modules/pua_dialoginfo.html#idm152 "This is a workaround for the buggy Linksys SPA962 phones. SNOM phones work well with the default setting." modparam("pua_dialoginfo", "caller_confirmed", 1)

How can I activate these settings only for the phones that have problems? Do I need a different Kamailio instance for each buggy phone that appears from a client ? For example, a Kamailio instance with modparam("pua_dialoginfo", "caller_confirmed", 1) for some (like Linksys SPA962) and the opposite for all the others (like SNOM) ?

Thank you,
