About

Pyhton3 script uses the pjsip library to call and play recorded audio to given numbers (CSV format).

Use Case

The script can initiate calls to multiple numbers and play a predefined recording after the call is received.
This type of application can be useful for businesses that want to announce information to their customers.

Features

  • Filter unique numbers.

  • Try to call a number "N" times ( "N" can be set by the user) before ignoring the number.

  • After execution, the script gives a detailed report about "Answered Calls" and "Unanswered Calls".


Steps To Use

Considering the script will be used on linux (ubuntu).

  • Follow this repository to set up pjsip/pjsua for python3.

  • Check if "pjsua" installed correctly.

  • Create "call_list.csv" to a folder. Use delimiter "\n" while adding numbers(the numbers you want to call) to the csv file.

  • Change the audio file (must be wav format) name to "play.wav". "play.wav" will be played to numbers when call is received.

  • Copy "script.py" script to the working folder (working folder refers to where "play.wav" & "call_list.csv" files exist).

  • Update username, user password, sip server address inside the script before execution (variables are named relatively).

  • Open a terminal inside the folder. Run "python3 script.py" to execute the script.


Note

  • While installing PJSIP carefully follow the steps. For first time it is better to use virtual machine.

  • Tested the script on Ubuntu Lts 20.04 ( Pjsip 2.10 & Python 3.8).

  • Tested with virtual numbers ( here virtual number referring such number which uses sip protocol).
