Thanks for spotting it, I pushed a commit adding a note about availability of sr Lua module by loading app_lua_sr Kamailio module as well as updated the Lua script examples to use KSR instead of sr.

But, on the other hand, the example in the docs for lua_dostring() does not have the line you pasted:

lua_dostring("KSR.pv.seti(\"$$var(var1)\", $avp(var1) < $avp(var3) and 1 or 0)");

just assuming is was on your local testing.

Cheers,
Daniel

lua_dostring("sr.pv.seti(\"$$var(var1)\", $avp(var1) < $avp(var3) and 1 or 0)");

results in error :
kamailio app lual_dostring(): error from Lua:  attempt to index global 'sr' (a nil value)

replacing sr with KSR is working :

lua_dostring("KSR.pv.seti(\"$$var(var1)\", $avp(var1) < $avp(var3) and 1 or 0)");

Shall we update the docs for
https://kamailio.org/docs/modules/devel/modules/app_lua.html#app_lua.f.lua_dostring ?
