Play music on hold while LUA task execution

[ewdpb]

Hi all,

I have an IVR that executes some API requests. A couple of those may take 3 to 5 seconds to come back with a result (this is expected, not a bug - it is the backend system taking that long - it is is not ideal but it is what it is). I was wondering if there is a way to play music on hold (or anything else) back o the user while they wait for the API execution to be completed.

As always, any advice is appreciated.

Thanks!

Oof... I'm still learning the lua api myself, but in the Freeswitch Lua API Reference I found the streamFile action.

session:streamFile("/tmp/blah.wav");

Hi @bryanredeagle , thanks for replying. The streamFile function is blocking, so, the next instruction has to wait until the playback end. Also what I am looking is for a way to stream a file while the caller is waiting for another thing to happen, that is paralllel executions.Thanks for the idea though!

You could look into uuid_broadcast which seems to be async, you can use it to execute another dialplan.
The examples in the docs look promising;

Thanks @Dast . That is interesting. I'll give it a try!
