perhaps this old reference to openser in ul_mi.c should be replaced by a Makefile.defs variable:

/*! call-id used for ul_add and ul_rm_contact */ static str mi_ul_cid = str_init("dfjrewr12386fd6-343@openser.mi");

also this string could be a variable:

/*! user agent used for ul_add */ static str mi_ul_ua = str_init("Kamailio MI Server");
