All the big chip vendors are jumping on to the VoIP bandwagon. Texas Instruments was the first one to the party, and then came the likes of Broadcom. Joining the ranks of the VoIP chip makers is PMC-Sierra which today announced chips that go into Residential and SOHO broadband gateways, Analog Telephone Adapters (ATA) and small enterprise class IP based PBXs. These chips are based on the MIPS core.
