  AT&T API Platform Samples - CMS App 1
 -------------------------------------

This application demonstrates the usage of Call Management API of AT&T platform.
The application provides operations to support the creation of outgoing call session
and signals to existing sessions. Incoming call sessison will be created automatically
in the call environment.

This file describes how to set up, configure and run the PHP Application of the
AT&T API Platform sample applications. It covers all steps required to register the
application on DevConnect and, based on the generated API keys and secrets,
create and run one's own full-fledged sample applications.

  1. Configuration
  2. Installation
  3. Parameters
  4. Running the application

1. Configuration

  Configuration consists of a few steps necessary to get an application registered
  on DevConnect with the proper services and endpoints, depending on the type of
  client-side application (autonomous/non-autonomous).

  To register an application, go to https://devconnect-api.att.com/ and login with
  your valid username and password. Next, choose "My Apps" from the bar at the top
  of the page and click the "Setup a New Application" button.

  Fill in the form, in particular all fields marked as "required".

  Be careful while filling in the "OAuth Redirect URL" field. It should contain the
  URL that the oAuth provider will redirect users to when he/she successfully
  authenticates and authorizes your application.

  NOTE: You MUST select Call Control in the list of services under field 'Services'
  in order to use this sample application code.

  Having your application registered, you will get back an important pair of data:
  an API key and Secret key. They are necessary to get your applications working with
  the AT&T Platform APIs.

  Initially your newly registered application is restricted to the "Sandbox"
  environment only. To move it to production, you may promote it by clicking the
  "Promote to production" button. Notice that you will get a different API key and
  secret, so these values in your application should be adjusted accordingly.

  Depending on the kind of authentication used, an application may be based on either
  the Autonomous Client or the Web-Server Client OAuth flow (see
  https://devconnect-api.att.com/docs/oauth20/autonomous-client-application-oauth-flow or
  https://devconnect-api.att.com/docs/oauth20/web-server-client-application-oauth-flow
  respectively).


2. Installation

   Requirements:
     Apache web server
     PHP 5.4+
     PHP CURL extension
     Apache and PHP configured. The package manager on most GNU/Linux systems should automatically
     configure Apache/PHP upon installation.

   Installation:
     Install Apache, PHP, and PHP CURL extension according to their respective documentation.
     Copy the sample application folder to Apache web root folder, for example /var/www/html.


3. Parameters

  Each application contains a config.php file. This file holds configurable parameters described in an
  easy-to-read format. Please modify the config.php file using the comments specified within the file.

  Note: If your application is promoted from Sandbox environment to Production environment and you decide to use
  production application settings, you must update parameters as per production application details.


4. Running the application

  After the sample application folder has been copied to the Apache web root folder, you need to start Apache.

  Once Apache has been started, use a web browser and open the the web page to where you copied the sample application folder.
  For example, http://localhost/app1/index.php

	AT&T API Platform Samples - CMS App 1
	-------------------------------------

	This application demonstrates the usage of Call Management API of AT&T platform.
	The application provides operations to support the creation of outgoing call session
	and signals to existing sessions. Incoming call sessison will be created automatically
	in the call environment.

	This file describes how to set up, configure and run the PHP Application of the
	AT&T API Platform sample applications. It covers all steps required to register the
	application on DevConnect and, based on the generated API keys and secrets,
	create and run one's own full-fledged sample applications.

	1. Configuration
	2. Installation
	3. Parameters
	4. Running the application

	1. Configuration

	Configuration consists of a few steps necessary to get an application registered
	on DevConnect with the proper services and endpoints, depending on the type of
	client-side application (autonomous/non-autonomous).

	To register an application, go to https://devconnect-api.att.com/ and login with
	your valid username and password. Next, choose "My Apps" from the bar at the top
	of the page and click the "Setup a New Application" button.

	Fill in the form, in particular all fields marked as "required".

	Be careful while filling in the "OAuth Redirect URL" field. It should contain the
	URL that the oAuth provider will redirect users to when he/she successfully
	authenticates and authorizes your application.

	NOTE: You MUST select Call Control in the list of services under field 'Services'
	in order to use this sample application code.

	Having your application registered, you will get back an important pair of data:
	an API key and Secret key. They are necessary to get your applications working with
	the AT&T Platform APIs.

	Initially your newly registered application is restricted to the "Sandbox"
	environment only. To move it to production, you may promote it by clicking the
	"Promote to production" button. Notice that you will get a different API key and
	secret, so these values in your application should be adjusted accordingly.

	Depending on the kind of authentication used, an application may be based on either
	the Autonomous Client or the Web-Server Client OAuth flow (see
	https://devconnect-api.att.com/docs/oauth20/autonomous-client-application-oauth-flow or
	https://devconnect-api.att.com/docs/oauth20/web-server-client-application-oauth-flow
	respectively).


	2. Installation

	Requirements:
	Apache web server
	PHP 5.4+
	PHP CURL extension
	Apache and PHP configured. The package manager on most GNU/Linux systems should automatically
	configure Apache/PHP upon installation.

	Installation:
	Install Apache, PHP, and PHP CURL extension according to their respective documentation.
	Copy the sample application folder to Apache web root folder, for example /var/www/html.


	3. Parameters

	Each application contains a config.php file. This file holds configurable parameters described in an
	easy-to-read format. Please modify the config.php file using the comments specified within the file.

	Note: If your application is promoted from Sandbox environment to Production environment and you decide to use
	production application settings, you must update parameters as per production application details.


	4. Running the application

	After the sample application folder has been copied to the Apache web root folder, you need to start Apache.

	Once Apache has been started, use a web browser and open the the web page to where you copied the sample application folder.
	For example, http://localhost/app1/index.php
