[sr-dev] some missing kemi module functions

[David Escartin]

Dear Daniel

i have been rewriting all the native configuration we have for a proxy to
kemi lua and i'm (i think) having it working fine, but i'm still missing
some functions to be migrated, some of those are not even working with
KSR.x.modf
Now i'm using version: kamailio 5.4.0-dev2 (x86_64/linux) f268aa

-be able to select facility on KSR.xlog, equivalent to xlog("LOG_LOCAL7",
"L_NOTICE", "$var(x)");
-sipt module functions
-dialog dlg_set_ruri function (maybe some others), this is now even working
with modf (ERROR: app_lua [app_lua_api.c:1633]: sr_kemi_lua_modf():
function 'dlg_set_ruri' is not available)
-tm t_relay_to_tcp

if you have any update about this function exportation, it would be great

best regards
david
