Fax App (innovaphone-fax)

This app is provided for the users to send fax documents and view or download received documents. The app reads the argument mailbox=<sip name> to work with the given account instead of the user logged in. It uses the API to search for contacts with FAX numbers.


The Fax App PBX Manager Plugin configures the App service and adds/modifies the corresponding App objects in the PBX. Additionally, it will find, register and configure available Fax-interfaces to the Fax App.
As with any app, the Fax-App needs then to be assigned to a user and licensed accordingly.

If FaxtoMail should be used, you need to make sure that the SMTP configuration is done in the Fax App PBX Manager Plugin. Additionally, each user has to enable FaxtoMail and choose the notification type (with or without PDF-attachment) in the Burger-Menu of his/her Fax or GroupFax - App.

If there occurs an error in the SMTP procedure (syntax error, mail server is not reachable, etc.), failed mails will be retried each 30 minutes.

Faxes deleted via the Fax App are removed from the database after two weeks.
