We could have just taken the existing 4-trunk Prosody X PCIe board and added further trunks and DSPs. Instead we took note of customer feedback and went the extra mile to further improve the original design.
The result is a board with vastly increased channel capacities, giving our developer customers the components needed to readily craft large scale systems at a very cost-effective price-per-channel. Whilst many DSP boards top out at 240 channels, the new 8-port Prosody X PCIe board can support up to 720 channels.

Gigabit Ethernet connectivityOne of the main areas of improvement with the new board was the addition of Gigabit Ethernet connectivity as an option. Earlier PCI and PCIe Prosody X boards were fitted with dual Fast Ethernet interfaces as this was appropriate for the channel capacities possible. Gigabit Ethernet was available only on the cPCI form factor Prosody X boards that, with up to 8 DSPs and 16 E1/T1 trunks, can exploit the bandwidth offered by such an interface.

As communications platforms increasingly become more IP-traffic centric, so the importance of communications hardware, such as Prosody X, that is highly efficient in dealing with VoIP, gains in importance.
In conclusion, if you are looking for a way to build cost-effective, medium or large scale IVR, call-centre, fax server, conferencing server or similar enterprise/telco platforms then you should check out what Aculab and Prosody X can offer. You will be pleasantly surprised.
