Why DSPs?

Sounds like a silly question -- why do we need DSPs? of course to offload off the router encoding, and other voice features -- but out of curiosity -- since hardware is cheap nowadays, why do we even need a DSP? Why not just get a router with 4 GB or RAM and your set?


Whats the point of having an additional set of "RAM"/DSP to do the voice features when RAM Is cheap nowdays and can be put onto a router and/or server?

    The DSP is more than memory. It is the Digital Signal Processor that performs the actual voice encoding and decoding.  This is where the actual voice CODECs are doing thier magic.
