musachowdhury/pjsip-based-python3-bulk-calling-script

The bulk calling script is written in python3 which uses the pjsip library (pjsua).

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).
