The idea of the translations App is to provide an interface for other Apps to translate user content on-the-fly. So other apps can integrate the translation service via the local JavaScript API in the client and thus offer the user translated texts.

The service serves as a proxy and integrates a corresponding backend. This means that you need your own account at the external translations service and can configure your API key in the PBX Manager for this app service.

Pay per character (To save costs, the app service offers a cache to avoid multiple translations)


No license needed


Go to the PBX manager and open the "AP app installer" plugin. On the right panel, the App Store will be shown. Hint : if you access it for the first time, you will need to accept the "Terms of Use of the innovaphone App Store"

  • In the search field located on the top right corner of the store, search for "Translations" and click on it
  • Select the proper firmware version, for example "v14" and click on install
  • Tick "I accept the terms of use" and continue by clicking on the install yellow button
  • Wait until the install has been finished
  • Close and open the PBX manager to refresh the list of the available colored AP plugin
  • Click on the "AP Translations" and click on " + Add an App"
  • Enter a "Name" that is used as display name (all character allowed) for it and the "SIP" name that is the administrative field (no space, no capital letters). e.g : Name: Translations, SIP: translations
  • Tick the appropriate template to distribute the App (the app is needed at every user object from any user who wants to use the translation API)
  • Click OK to save the settings and a green check mark will be shown to inform you that the configuration is good

Translation - Client

There is no view/app that the user can explicitly open. The service runs in the background and has no UI and can be integrated by other apps. In order for the user to have access to the translation service, their user object must have access to the app object of the translations app.

The client side of the app service receives requests from all other apps via the local JavaScript API and sends them to the service. The result of the request is returned to the original app via the local JavaScript API

Translation - App Service

The App Service performs tasks in the following areas:

  • Language recognition
  • Caching
  • Translations against the backend (

Language recognition

An offline API is offered to recognize the language used in a string. This recognition is also used for translations to avoid unnecessary translations (e.g. EN to EN translations are prevented). This payload will not be sent to any backend service, thus avoiding unnecessary costs.
A few features exist which should make sure, a recognized language is only considered, if there is enough confidence:

  • Strings shorter than 6 words are skipped, since the chance for false positives are relatively high
  • Strings in which are not enough word matches to be confident for any language will be skipped, also because of high chances for false positives
  • Strings in which are more than one language with a nearly similar amount of word matches will be skipped

To save costs, all translations are cached in the App Services database. If a string is translated multiple times, only the first translation is carried out by the backend and the translated version is saved in the cache. A second translation is therefore free of charge and performs better.

Translations against the backend

Translation requests that cannot be handled by the local cache are forwarded to the configured translation backend. After successful translation, the translated version is kept in the cache for future requests.

To troubleshoot this App Service, you need the traceflags App, Database, HTTP-Client in your App instance.
