Hello Michael.

Yes we are doing ivr stuf using sync , mainly because we have some routines that require step by step and timing processing , like PIN verification , Security Clearance , etc.
This is mainly why i use mode sync ( I'm not telling you I'm right just trying to give you an ideia of what we are doing)

From my understanding , async is a full dump to FS of all the commands for that DP like :
Answer()
Speak (' Hello World')
GetDigits()
now if the person presses 2 , hears a menu with more options and presses another key.
What will call for example a program that send an SMS to give you an ideia.


Example :
Answer
Speak('Press 1 or 2')
GetDigits()

if dtmf == 1:
speak('bye')
elif dtmf == 2:
SendMySMS('blahblah')
speak ('now pres 3 4 or 5')
get digits()
if dtmf == 3:
etc , etc etc.


With step by step this is simple ( except the GetDigits Part)

Can you tell us more about how you're doing this? It sounds like you are doing IVR-ish stuff which, IMHO, does not lend itself for async ESL. I would rather see you do something akin to the fs_ivrd + perl ESL::IVR examples.

Good Morning.

I'm currently in the process of converting my IVR's into ESL , freedom :D.
From my testing is extremely flexible until i have reached a wall.

We use TTS to generate alot of information for our users then we need to collect some answers, in session i had GetDigists , yay :).
In ESL i have the DTMF event the problem is that from my testing and wiki , DTMF event is only send down the socket using asycn , now i need "sync" because the IVRs need to understand the exact position of the user and blah blah blah ,  need to be dynamically extended in realtime and would be hard to implement in async , specially the timing for digit collection.

So i tried capturing the event with no luck the only one i got is SERVER_DISCONNECT at the end.

I think It is possible if for every thread i would raise a listener for that specific uuid that would share memory with the first one so i could read that DTMF events that arrives trough the other socket but i think this is way to much duct tape for a simple thing.

So any help on this ?
Thanks
A/T
