Hello Everybody!

<![if !supportLists]>1. <![endif]>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:
<![if !supportLists]>- <![endif]>Receive DTMFs
<![if !supportLists]>- <![endif]>Have a timer that can call a certain function in my script. The script will have to play a message to party A.
<![if !supportLists]>- <![endif]>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.

<![if !supportLists]>2. <![endif]>Problem.
I will be happy to receive help on:
<![if !supportLists]>- <![endif]>Which methods should I look for to implement this.

<![if !supportLists]>3. <![endif]>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!

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 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.

Looks like I was wrong about using the native Python timers. Here is how they can be used in your script:

# Imports – add these new imports
import time
import threading

# class definitions – add this new class
class Timer(threading.Thread):
def __init__(self, seconds):
self.runTime = seconds
threading.Thread.__init__(self)
def run(self):
time.sleep(self.runTime)
console_log("debug", "TIMER ********************")

# entry point – add two rows in the entry point function that is called from freeswitch
def handler(session, args):
…
t = Timer(10)
t.start()
…

So what is now remaining is to get when the call CONNECTS and how to get DTMFs during the call.

Hoping that this will get the state of the call. If I call this check frequently I will catch the call connect I trust.

To get the state use:
session.getVariable("state")

I hope that I will solve the Timers puzzle soon. I am still looking on getting the DTMFs during a bridged call.
