Overview

The innovaphone SDK has 3 parts a developer needs to know to create apps for the app platform:

The library to develop the app-service for the app platform itself (C++ or JS)
The library to develop the app UI which runs in a browser or inside the myApps client (JS)
Websocket Messages and APIs that are used for communication between the individual components.

C++ library for App Services	Used to develop an app-service in C++ that is running on the app platform.
JavaScript library for App Services	Used to develop an app-services in JavaScript that is running on the app platform.
JavaScript library for Apps	A library to create the JavaScript UI for an app (if there is any).
APIs	There are different kinds of APIs that can be used for communication between different components of the system (app, app service, PBX).
Protocols	Different protocols used by Apps, e.g. the Sysclient protocol within the Devices App.
How to use the AppStore	The AppStore can be used to publish apps.

C++ library for App Services

The C++ library of the innovaphone SDK is a set of interfaces and classes used to create C++ apps to run on the app platform. The services provide everything an app needs to be registered into the app manager, access the a database, manage configuration, communicate with a PBX, have access to the outside world by using sockets or an HTTP client, be accessed from outside by registering itself as kind of a plugin into the app platforms webserver and more. Even if standard C++ will be used to develop an app, the app must use the interfaces to work proberly within the app platorm.
The following interfaces and classes are provided by the C++ library:

App Service Interfaces

JavaScript library for Apps

The UI for the app is written using JavaScript. The benefit is, that the UI runs inside a browser and the myApps client, the desktop or mobile devices. That also means, that the UI must be developed in a way to dynamically fit into the available size. For some of the base functionalities (like communication with the app-service, authenticating, loading of configuration, creating nodes), the JavaScript library provides some tools.

lib1	The fundamental library that is needed for all apps. It defines that start object that is the interface to the app runtime inside myApps. It also includes functions for translated texts and events.
appwebsocket	Library for authentication and communicating with the app service using a websocket connection.
crypto	Library for encryption, decryption and hashes.
crypto.ecdh	Library for ECDH(E) key agreement.
config	Library for configuration of the app.
countries	List of country names in English and in the local language.
phonenumber	Library that contains various functions related to phone numbers.

For building user interface using Javascript the SDK provides a slim library for creating and handling HTML elements.

ui1.lib	Defines the node prototype that is used for all UI classes. Also it defines classes for simple items (div, input, checkbox) and a library for color schemes and dynamic translated UI texts.
ui1.svg	SVG image

fonts	Collection of fonts used in the innovaphone apps.

APIs

Client APIs

Client APIs are used for communication between (web-)apps running in myApps. HTML5 Window messaging is used for transport between the IFrames. Each API defines an identifier (like com.innovaphone.phone), an API model and messages. Each Provider can has its own model that can be used to publish status information. Each app can provide and consume APIs. Hidden apps can be used for providing APIs in the background, without an UI being shown to the user. There is a bridge between the myApps webclient and the launcher, so that client APIs can also be provided or consumed by components of the launcher. Permission to client APIs is granted per user by allowing access to the corresponding

com.innovaphone.client	User details (display name, sip, phone number, email address, guid) Tiles on the home screen, Available phone apps, Profile app
com.innovaphone.launcher	Push token, User activity status (auto apear offline), Support for popup windows (only on computers, not on smartphones) URLs and passwords for launcher services, Touch support, Locking state of smartphones
com.innovaphone.search	Search in the contents of other apps (e.g. contact details)
com.innovaphone.phone	See registration status and current calls; Start calls; Provide call-related information to phone-app
com.innovaphone.phoneinfo	Recv information about current calls in real-time
com.innovaphone.phonelookup	Lookup phone numbers in databases (e.g. local Outlook addressbook) to find name formation for incoming calls
com.innovaphone.chat	Start chats
com.innovaphone.avatar	Base URL for profile picture, domain of the provider Key for authentication
com.innovaphone.calllist	Get recent calls
com.innovaphone.devices	Find/configure devices
com.innovaphone.devicesui	Show device (by MAC address or name)
com.innovaphone.events	Send events, alarms and logs
com.innovaphone.manager	Find app platforms, configure app platforms
com.innovaphone.files	Get shared announcements
com.innovaphone.discussion	Create an iframe containing a discussion
com.innovaphone.autostart	Autostart without user interaction for hidden apps.
com.innovaphone.translation	Get instant translations from external translation-services (eg. DeepL.com).
com.innovaphone.assistant	Access a remotely hosted large language model LLM.

App Service APIs

Service APIs are used for communication between App Services. Websocket is used for transport. Each API defines an identifier (like com.innovaphone.devices) and messages. The PBX API "Services" can be used to find Service PBX APIs and authenticate against them.

com.innovaphone.devices	Used to create provisioning codes.
com.innovaphone.channels	Used by the PBX to find a channels app service providers.

Launcher services

Launcher services accept websocket connections from apps. Apps can find and authenticate against launcher services using the Client API com.innovaphone.launcher. We used launcher services for call functionality that might be too load-intensive in a Client API (signalling, starting ring tones).

Media	Audio, video, appSharing, headset buttons
Ringer	Play ringtones

PBX APIs

The following APIs can be used with all AppWebsocket connections with the PBX. A permission for the API needs to be enabled at the app object.

Signal	This is the generic JSON signaling signaling protocol, which is mapped by the PBX to any standard Voip Signaling like SIP or H.323
PbxSignal	Protocol to register to the PBX and do signaling with the JSON signaling protocol
EpSignal	This protocol allows to attach to a device registered to the innovaphone PBX and intercept all signaling to and from this device
RCC	Perform remote call control operations with registered endpoints
PbxMessages	The protocol to retrieve stored chat messages
PbxApi	Presence monitoring and management of favourites
PbxAdminApi	Configuration of the PBX and pseudo objects
PbxTableUsers	User objects replication from the PBX to your app instance
Replication	Replication of tables. Use "api":"PbxTableUsers" to replicate the PBX user objects to your app instance.
Services	Finding and authenticating against other app services
Impersonation	API to use other APIs on behalf of a given user

Separate from that the PBX supports the following websocket protocols that are not related to AppWebsocket connections.

myApps

The protocol of the myApps client.

PBX REST and SOAP APIs

There are some REST and SOAP APIs that are supported by the PBX.

SOAP	The PBX provides an Api for call-control and administration features with the standard SOAP protocol. With a wsdl file this SOAP API can be integrated in many development environment. Please note that the functionality of that legacy API is available using the Websocket APIs RCC and PbxAdminApi. Implementations based in the current SOAP interface will remain working.
CDR	The PBX creates Call Details records, which may be delivered using several methods. These CDRs are XML documents created for individual users/objects of the PBX describing a call as seen by this user.
Recording	In phones as in gateway media-relay interfaces a recording URL can be configured, which is used to write media data of any calls to a HTTP server.

PBX Interface

There are PBX-Interfaces, which can be used by an app.

Textmedia

The PBX provides an interface for the transcription of Speech to Text.

Protocols

There are some protocols used by innovaphone Apps.

Sysclient	The sysclient protocol is used by devices to register in the Devices App.
Push	Protocol used between the PBX and the innovaphone Push service.

How to use the AppStore

After an app has been built, it can be published on the AppStore. Here you can find how to use the AppStore for this.
