Description
This 4th generation card is half height and comes by default with both full and half height metal bracket.
The card is manufactured with the highest quality components and PCB in our fully automatic Surface Mount Technology factory.
ALLO supports the AsteriskTMÂ community and has opted NOT to copy the DigiumTMÂ PCI ID, like other manufacturers do unlawfully and against the will of DigiumTM. For you, the customer, this means you are buying a card which will continue to work with DAHDI when DigiumTM, the owner of AsteriskTM, decides to change their code in order to block the rogue manufacturers. Use our patched DAHDI version provided.
Should you choose to purchase the optional Line Echo Cancellation module which uses the industry standard Octasic®DSP, you will also receive for FREE our Conference Room Software. Once installed, the software allows you to set up, schedule and manage conferences which are MIXED IN THE Octasic® DSP.
We guarantee that our card, working directly with DAHDI (no patch required), delivers the same sound quality and performance as the DigiumTMÂ and SangomaTMÂ cards while costing considerably less.
PRI cards today became a commodity since all manufacturers use FPGAs and the same OctassicTMÂ DSP for their Echo Cancellation. Not only our cards perform at par with the larger manufacturers but they also offer the Innovative and Unique PCI/PCIe Rotation System (see video).Available in 4 port, use this card with any of the major open source platforms.
