HiPath BizIP

HiPath BizIP and the powerful BizIP phones are self-configuring, offer personal voice mail for every user and manage your voice and data traffic over your existing network infrastructure.


Unify provides the market with a new technology for Voice over IP (VoIP) using P2P architecture. HiPath BizIP is a pure VoIP solution and needs just phones.

The access device BizIP AD 20 handles communication with public voice and data networks (ISDN and Internet). The intelligent BizIP 410 phones are connected to the customer LAN. They can find each other and configure themselves automatically, so they are ready to use immediately. Each phone includes a built-in Voice mail and a feature set optimized for VoIP.

For external communication the customer can use multiple SIP accounts from a VoIP Service Provider, traditional ISDN phone lines or both. The solution aims at very small to small companies. Through auto-configuration it offers ‘Plug-and-Phone’ capability for the customer. Expansion for additional users up to 16 phones is very easy.
