Eqivo | Open Source Telephony API Platform

Eqivo is an open source telephony/real time communications API platform.

Eqivo started as a tribute project/reimplementation of the discontinued Plivo Framework, not to be confused with the cloud offering by the same company; there is no affiliation between the latter company and the Eqivo developers. For clarity, the original (now discontinued) project shall be referred to as the legacy framework.

To learn more about it, read the project's mission statement and its documentation, as archived by the Wayback Machine circa 2017.

It relies on FreeSWITCH for signalling (SIP, Verto, etc.) and media (RTP) handling. Eqivo sits between FreeSWITCH and your application and interacts with the latter by accepting inbound API calls as well as issuing outgoing webhook calls to your designated endpoints.

Being a reimplementation of the legacy Plivo framework, Eqivo can function as a drop-in replacement for most use cases. It also features several extensions, including M:N (Eqivo:FreeSWITCH) deployment configurations and answering machine detection.

Overview

Out of the box, the legacy framework was intended to be deployed alongside FreeSWITCH, seemingly at host level as containers were not as popular back then. Fast forward a decade later, Eqivo is optimized for container based deployments and breaks away from the 1-to-1 relationship with FreeSWITCH. Internally, Eqivo follows most (yet not all) design principles of the legacy framework. A great deal of terminology is also borrowed for the latter project.

Initiating Actions

In order to initiate various actions, your application will invoke the Eqivo RestAPI. It's backwards compatible and the interactions are fairly straightforward, all requests must:

• employ RFC 7617 Basic authentication, the Authorization header must be included in every request;
• use POST method for all calls. Parameters must be application/x-www-form-urlencoded endcoded;
• expect a JSON response for successful requests as well as application-level errors.

Handling Events

Your application must expose endpoints Eqivo will invoke when certain events occur. For example, when an inbound call lands on a FreeSWITCH instance, Eqivo will hit a designated endpoint on your application expecting a well formatted XML response describing how the call in question should be handled. The RestXML implementation is backwards compatible.

Getting Started

Installation

OCI Container

docker pull rtckit/eqivo
docker run rtckit/eqivo

Container deployment is the recommended method for integrating Eqivo in your applications; ready-made OCI images are available on DockerHub. Configuration via environment variables is ideal for this approach, and orchestration systems such as Kubernetes can transparently handle secret management on your behalf.

For every release, there are two images available, the production one (using version tags) which contains only Eqivo and the PHP runtime and its dependencies. There is also a debug image (tagged with the -full suffix) which includes a complete Debian userland to facilitate troubleshooting.

Phar Package

curl -Ls https://github.com/rtckit/eqivo/releases/download/v0.6.1/eqivo.phar -o eqivo
chmod +x eqivo
sudo mv eqivo /usr/local/bin
eqivo

The project is also available as a standalone Phar package, in which case the environment must be properly configured, i.e.: PHP 8.1+ as well as required extensions (typically bundled with the PHP core).

During startup, Eqivo will check if its dependencies are met and it will complain if something is wrong.

Git Repository

git clone https://github.com/rtckit/eqivo.git
./bin/eqivo

Lastly, you can clone the GitHub repository and launch Eqivo manually.

Configuration

The default configuration values alone will not result in a meaningful Eqivo running instance. Furthermore, there is no boilerplate configuration template as each integrating application is unique. All options are documented in their respective chapter, however it is important to understand how Eqivo interacts with your application and FreeSWITCH so one can configure it properly.

Eqivo ⇆ FreeSWITCH

At least one running FreeSWITCH instance (aka core) must be configured, which consists of a host name, a port number, a password and an optional user name. It's important to note your network/firewall settings must allow Eqivo to connect to the configured host:port pair over TCP.

For the reverse control flow, Eqivo exposes a service (referred to as the outbound server) which intakes notifications from FreeSWITCH. outboundServerBindIp and outboundServerBindPort are defining the socket address pair where Eqivo is listening at and the network/firewall settings must ensure FreeSWITCH is allowed access to it.

Eqivo ⇆ Integrating application

Eqivo forwards various events by invoking webhooks managed by your application. These are either predefined (such as defaultAnswerUrl, defaultHangupUrl, recordUrl or callHeartbeatUrl) or set dynamically as API request parameters. The network/firewall settings must ensure Eqivo is able to access the configured webhooks.

For the reverse control flow, Eqivo exposes a service (referred to as the REST server) which intakes API requests from your application. restServerBindIp and restServerBindPort are defining the socket address pair where Eqivo is listening at and the network/firewall settings must ensure your application is allowed access to it.

Several common scenarios and a sample Docker Compose configuration are available in the rtckit/eqivo-sandbox repository.

Configuration

From a drop-in replacement perspective, Eqivo can function out of the box using legacy framework configuration files. It is however capable of more modern configuration intake facilitating both development as well as production deployment.

Eqivo is able to read configuration from static files (JSON and YAML format, resolving to the same schema), command line arguments and environment variables. Furthermore, one can mix these configuration channels as they see fit. For example when developing locally, one could set the EQIVO_VERIFY_PEER environment variable to false to bypass certificate validation yet retaining the baseline configuration which will eventually be used in production.

Sample configuration files can be found in the git repository: current YAML file, current JSON file and legacy configuration file.

RestXML

Inherited from the legacy framework, RestXML refers to a small set of specialized XML elements describing how calls should be handled. In a way, you can think of RestXML being an evolved dialplan, one that's easier to program in dynamic contexts. On each occasion when Eqivo needs RestXML in order to control a call, it will fire an HTTP(S) request to a designated endpoint, typically via POST although GET is also possible.

<?xml version="1.0" encoding="UTF-8" ?>
<Response> 
    <Speak>Welcome!</Speak>
    <Speak>To whom do I have the pleasure of speaking with?</Speak>
    <Record action="https://example.com/endpoint/got_name/" fileName="caller_name" />
    <Speak>I'm sorry, I didn't get that!</Speak>
</Response>

The request's payload includes critical parameters such as identification for both the caller and the callee, FreeSWITCH node responsible for the call and even the Eqivo node handling it.

RestXML structures must present a parent <Response> node which contains the elements to be executed (top to bottom). Element names and attributes are case-sensitive.

Conference

The <Conference> element allows you to connect different individual call legs together via a conference room; mod_conference's documentation can shed more light over the under-the-hood mechanisms.

Important conference room characteristics:

• naming of conference rooms is up to your application's use case;
• capacity (maximum amount of participants) can be controlled via FreeSWITCH, yet capped by system's resources;
• conferences don't effectively start until at least two members are present;
• whilst alone, music-on-hold can be played back;
• when members enter and exit, notification sounds can be played.

Basic usage:

<?xml version="1.0" encoding="UTF-8" ?>
<Response>
    <Conference>1912</Conference>
</Response>

Allow members in but don't kick off the conference yet:

<?xml version="1.0" encoding="UTF-8" ?>
<Response>
    <Conference startConferenceOnEnter="false">1912</Conference>
</Response>

Conversely, for "moderator" users:

<?xml version="1.0" encoding="UTF-8" ?>
<Response>
    <Conference startConferenceOnEnter="true" endConferenceOnExit="true">
        1912
    </Conference>
</Response>

Conversely, the <Dial> element attributes have a broader scope.

When multiple <Number> elements are present, the first connected destination is bridged and all other attempts are cancelled.
