PAPAGENO is a unified messaging server for companies that want to integrate fax, voicemail, SMS and landline SMS into their existing application environment. The server forms the link between the mail server and the phone system or public telephone network; messages and user addresses are stored and managed centrally. Users send faxes through clients, mail gateways connect existing mail systems and an XML interface serves process-driven applications. According to the provider, organisations that prefer not to install it themselves can use its cloud fax service instead (fax-as-a-service).
The maker is VIPcom GmbH in Munich, Germany. The software is installed on your own servers, for Windows and Linux, so you decide where messages and addresses are kept. The website does not say where the cloud service runs; ask the provider, especially if you consider the cloud variant. The website mentions no foreign parent company. For a European organisation the self-hosted variant is the most relevant, because no fax data then goes to an external provider.
