Actually Oki's just the fab. Oki is one of several manufacturers who will make you your custom silicon, if the quantities are right. We buy ASICs from an OEM for vector-control VFD products. The OEM has Oki fab and package the chip.
OKI produce a lot of telecoms chips of their own, and they also have a foundry business. They do produce their own echo cancellers, as well as other DSP functions for telecoms. What makes you think these are foundry chips?
