How to write PHP Client for accessing IVRS Push Call API?

Note: For using IVRS Push Call API you need Transport Layer Security(TLS) protocol version TLSv1.2

Steps to check whether your system supports TLSv1.2:

• 1) Run the following command on your system
  curl --tlsv1.2 https://msdgweb.mgov.gov.in/esms/sendsmsrequest
  
  2) If you get message "GET Method Not Supported" then it is SUCCESS!!! your system supports TLSv1.2
  
  3) If step 1 is not successful you need to upgrade your openssl libraries for system to suppot TLSv1.2 protocol
