[Freeswitch-users] Help Needed Debugging Lua Script

[Sina Owolabi]

Hi List,

I think I have finally come up with something that works, the script
captures the details correctly, but I wonder if there is a better way to
write it? I am trying to get it to call the dialer back and play a message,
which it does correctly.
Please what can I do to make it to retry the dialler's number in case the
call doesn't go through the first (say) two times, just in case the dialler
cut it off mistakenly, or the telco plays a repeated message after
freeswitch hung up, preventing the callback from coming through? (I've seen
this happen a few times with a local telco). Thanks!

number_to_call = argv[1];
caller_id = argv[2];
api = freeswitch.API();
dialString =
"{origination_caller_id_name="..caller_id..",origination_caller_id_number="..caller_id.."}sofia/gateway/sipgw/"..number_to_call.."";
session1 = freeswitch.Session(dialString);
session1:sleep(5000);

if (session1:ready()) then
        session1:sleep(35000);
        api:execute("bgapi originate", "session1");
        session1:sleep(3000);
        session1:streamFile('/tmp/stop_calling_me_stalker.wav');
        session1:hangup("NORMAL_CLEARING");
end
