Asterisk™ PBX

Asterisk ist eine Open-Source-Software, mit der Sie einen normalen PC in eine VoIP-Telefonanlage verwandeln könnten. Durch den Einbau von speziellen ISDN-Karten oder Analogadaptern lassen sich neben SIP-fähigen Telefonen auch ISDN- und Analogtelefone anschließen.
Because the installation and configuration of an Asterisk PBX is not easy, some system providers offer preconfigured systems.
