ALLO supports the AsteriskTM community and has opted NOT to copy the DigiumTM 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 Octassic® 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 Octassic® DSP.
