IP PBX Unified System for Paging and Access Control



A Wahsega IP PBX is an advanced paging IP PBX hardware appliance that allows Wahsega customers to easily create a full VoIP communication system with Wahsega’s intercoms, paging adapters, IP phones, ceiling speakers as well as any third-party SIP compliant devices. The Diet PBX hardware appliance targets paging and access control intercom deployments in the education, correctional facilities, healthcare, industrial and manufacturing, office buildings and hospitality markets. The Diet PBX is a key component when combined with Wahsega’s paging, IP speakers and intercom offerings to form a complete solution for paging and access control intercom applications.

Since the Diet PBX is an embedded appliance, not an application running on a PC or a Linux platform, it allows for rapid, fully functional boot times of 10-20 seconds and has near zero risk of viruses, and it is impervious to all common hacking methods. It is also designed to operate at Industrial temperature extremes (-40C to +85C). With the Diet PBX’s built in DHCP Server, it allows for simple LAN islands for paging and intercoms without the cumbersome setup issues using VoIP devices in peer-to-peer mode with static IP addresses.

What makes the Diet PBX unique is its super set of paging functionality and ease of deployment capabilities.
