So, I've been reading about early media in the wiki, and have made a little progress, which leads to more questions.
I understand now why a call is considered connected before one person has picked up the phone. I am also able to get my script to wait for the phone to be picked up, by setting the ignore_early_media variable when starting a new session, like this:
customerSession = freeswitch.Session("{ignore_early_media=true}sofia/gateway/
example.com/" .. customerPhoneNumber)
After that line, the script waits for the other phone to be picked up.
However, now I wonder what to do with calls that don't complete, get busy signals, etc.
What do people do in this case? The only related example I can find on the web is for a javascript dialer, which doesn't address any of these cases.
I guess it depends on what you want to do. For example I have a lua script very similar to what you describe, although there is no confirmation involved. Depending on the hangup cause the session gets, it might try redialing with a different gateway, try again or just hangup.
Here's an example in code which retries a call depending on the hangup cause. It retries max_retries1 times and alternates between 2 different gateways:
session1 = null;
max_retries1 = 3;
retries = 0;
ostr = "";
repeat
retries = retries + 1;
if (retries % 2) then ostr = originate_str1;
else ostr = originate_str12; end
freeswitch.consoleLog("notice", "*********** Dialing Leg1: " .. ostr .. " - Try: "..retries.." ***********\n");
session1 = freeswitch.Session(ostr);
local hcause = session1:hangupCause();
freeswitch.consoleLog("notice", "*********** Leg1: " .. hcause .. " - Try: "..retries.." ***********\n");
until not ((hcause == 'NO_ROUTE_DESTINATION' or hcause == 'RECOVERY_ON_TIMER_EXPIRE' or hcause == 'INCOMPATIBLE_DESTINATION' or hcause == 'CALL_REJECTED' or hcause == 'NORMAL_TEMPORARY_FAILURE') and (retries < max_retriesl1))
Note: originate_str1 and originate_str2 are two different dial strings for 2 different gateways.

Hi Rob!
Unfortunately, I have the next few weeks to complete this part of the project. Without a stable release of 1.0.5, I have to stick with 1.0.4. I'm sure that 1.0.4 can detect and report when a phone is picked up. It's just that I can't figure out how to get that information! Either that, or I have something mis-configured.
