"Yet" being the key word. Digium is wise to take advantage of on-board/hardware DSP where possible. Many so-called "high-end" card manufacturers (e.g. Natural Microsystems) have DSP built right on to their cards. As a consumer using two separate systems that use these "high-end" cards I can tell you that there is an industry bias against "the little guy with no DSP on his T1 card." (This bias reminds me of the Microsoft snobbery against Linux in the late 1990's.) Some industry players, including vendors who create apps using these high-end T1 cards, think that a Digium or Sangoma card without DSP on the card itself is just a toy. Their thinking is like, "Well my NMS Quad T1 board costs US$15000 - it must be WAY better than a $2500 card from Digium/Sangoma/whomever." Now that Sangoma, with Digium hot on their heels, have T1 cards with some on-board muscle, it is getting more difficult for the big boys to dismiss "those annoying open-source geeks."

I definitely like it. On-board DSP has advantages in higher-end applications where clients are willing to spend $, whereas the "dumb" cards also have a wide range of applications that will fill the needs of the budget conscious consumer. Kudos to Digium on this one! Keep us posted on the progress - I think this will be a quantum leap forward for the open-source telephony community. -MC _______________________________________________ --Bandwidth and Colocation provided by Easynews.com -- Asterisk-Users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
