A D-Link kiadott egy teljes fejlesztői környezetet a VoIP router-éhez. A környezet egy Kubuntu LiveDVD-n található.
"According to D-Link open source is an important component of its product strategy. “That a complete development environment would be made available was already apparent when HorstBox Professional was still in its conception phase. The reason for this is obvious: The requirements that future-proof systems capable of flexibly responding to the desires of customers need to meet are continuing to grow. In this way we can meet these requirements in an optimal fashion,” Horst Toddenroth, head of the Advanced Products and Solutions Department at D-Link Central Europe, said."
