Hello Michael!

Thank you for your reply! I know about sched_api and I use Python as a scripting language. Also “sched_api” can be used inside python, using session.execute. However the problem is that the “sched_api” timer starts right after you initiate the SETUP of the second call leg. What I need is to call something, after a call CONNECT instead. One workaround would be if I can check what time it took to connect the call, but I do not know/see how to do this. I do not see a CONNECT callback function either.

P.S. Dear enlightened people, thank you for providing help to the community by replying to the list e-mails.

Subject: Re: [Freeswitch-users] Timers/DTMFs During a Call

Do you actually need Python for the IVR, or is it that you're comfortable using a scripting lang for an IVR? I like using XML for IVRs, but using scripting langs does give you a bit more power & flexibility at the cost of some resources.

For the record, you can do this in the dialplan using XML and sched_api without touching a scripting language. Checkout the sched_api channel variable on the wiki - it may give you the functionality you need.

Hello Everybody!

1. Scenario.

I am writing an IVR in Python that gets a destination from the calling party (party A) and then connects to the destination (party B).

When the call is CONNECTED, I want to:

- Receive DTMFs

- Have a timer that can call a certain function in my script. The script will have to play a message to party A.

- Have a timer that can call a certain function in my script. The script will have to drop the call.

Please notice that I want to do the things after the two parties are connected, and not after I send the Invite to party B.

2. Problem.

I will be happy to receive help on:

- Which methods should I look for to implement this.

3. Details

Here is how I connect the call currently:

session.execute("bridge",”sofia/internal/" + destination_number + "@domain.com”)

I have tried to create a timer callback function “my_method()” using:

ivr_timer =threading.Timer(30,my_method)

This never called the function “my_method()”.

Maybe I am wrong in using threading.Timer and the “bridge” application? Maybe I need to create a new thread and a new timer using the API of freeswitch, plus to use the “session.setInputCallback”, plus use a conference rather than a bridge? Can you please provide any suggestions or examples?

Thank you!
