Tony, Thanks for the explanation. This was indeed my concern with trying to do it from a dp script. Sid, I'm afraid you'll need to use ESL or find a girl who is not bound by the laws of physics... :) -MC On Fri, Jun 17, 2011 at 10:30 AM, Anthony Minessale < anthony.minessale@gmail.com> wrote:
In this case, it turns out you are asking the girl to defy physics for you.
The session is executing the script code in the same thread that needs to play the audio. You cannot magically do 2 things at once in the same thread so.... using ASYNC (esl) is your only choice apart from using C and threads or launching the lua script in another thread with luarun with the channel uuid as an arg so it can feed it to the constructor and send commands to it remotely which is a pretty big mess.....

Thanks Michael. This is quite a mainstream requirement :-) ! Not everyone uses ESL. Is there no way we can "hack" this in Lua?
Will await your research,

Actually, I am looking into ways to accomplish these. They are somewhat related to some recipes I am doing for the FS Cookbook. Please stand by. FYI, I am looking at an ESL-based solution, not a dialplan script. Thus
far
I have not found a viable way to do async stuff like this from a dp script and I'm thinking ESL is the way to go. I will report back in a bit. -MC

I am implementing an IVR using Lua in Freeswitch. In my Lua script I
use
curl to a web service. Sometimes the response takes a long time to come back. During that time period I would like to play music on hold.
I have searched the freeswitch discussion archives a lot. There seem to be many suggested ways to implement music on hold from a Lua script but the answers are not very clear / not really applicable to my use case. I don't know what method I should use and which one is recommended.
Method 1: Transfer the call to 9664 (music on hold extension). However the implementation for this solution for this does not seem to be available in Lua. For example: How would I transfer the call back? Method 2: Using bgapi uuid_park park the call and using uuid_broadcast play an audio file. Again what do I do to unpark the call..?
Thanks,
Sidharth [P.S. This is a repost, I apologize but I never got any responses on my previous email. Need help! :-) ]
