I have a lua script that originates a call: local s = freeswitch.Session ( "{ignore_early_media=true,origination_caller_id_name=" .. caller .. "}loopback/" .. destination .. "/default/XML") s:execute ("sleep", "1000") ... which works fine if a valid number is supplied. However if a invalid number is supplied, then the script hits: [ERR] switch_cpp.cpp:607 session is not initalized [ERR] freeswitch_lua.cpp:102 session is not initalized What's the recommended way to check if the session constructor was successful (i.e. the number could be dialed)? My other option is: local s = freeswitch.Session () local r = s:originate (nil, "{ignore_early_media=true,origination_caller_id_name=" .. caller .. "}loopback/" .. destination .. "/default/XML", 300) if r == 1 then stream:write ("-ERR call failed\n") return end which does handle invalid numbers however there are the minor issues such as: a) The documentation seems to strongly discourage using the originate method for some reason. b) The lua originate method seems to require timeout to be specified even though the documentation implies it's optional. c) Using this approach causes the message: [WARNING] mod_limit.c:576 USAGE: hash [insert\|delete]/<realm>/<key>/<val> which I have yet to track down.

Doesn't work ... s is never nil. Type shows it as userdata
even if Session failed. Specifically my test was:

local s = freeswitch.Session (
"{ignore_early_media=true,origination_caller_id_name=" ..
caller .. "}loopback/" .. destination .. "/default/XML")

stream:write (type(s))

if s == nil then
stream:write ("-ERR call failed\n")
return
end

and I dialed an unreachable number.

Quote:

Checking s.ready() results in:

[ERR] freeswitch_lua.cpp:102 session is not initalized

if Session failed.

What I'm looking for is a way to try to originate a call which doesn't
throw ERR messages if the attempt fails.

Explicitly calling session.originate seems to allow you to check if
the call was successful ... is there a particular reason it's discouraged?

I'm happy to avoid it if a better approach is available, however I'm
having trouble finding one.

I think this is an oversight
update to trunk and session.ready() should work as expected.
