Why an IP-centric telephony board is the best choice when building highly scalable or resilient solutions

In putting IP research at the heart of the Prosody X design it is much simpler, due to the ubiquity of Ethernet in IT networks, to build multi-board, multi-chassis and multi-location systems using Prosody X. So if the high channel counts of a single Prosody X board are not enough, at the time it is easy to build multi-board systems.

The telephony world

Before VoIP (Voice over Internet Protocol) entered the telephony world, we depended on TDM research and an array of disparate CAS and CCS type PSTN protocols, and most of the voice-based solutions had a common architecture, simply described as a host server with telephony boards. Voicemail, interactive voice response, call centre or fax broadcast solutions had a common architecture with all parts integrated in one physical unit.
