Support and processing for VoIP falls into a wide spectrum of product types, from line cards in infrastructure devices to desktop phones.  ARM’s full range of processor cores is ideal for meeting the wide performance requirements of this market.  For higher-end VoIP products, including voice infrastructure gateways, there are a number of chipsets combining an ARM core with digital signal processing engines or a DSP processor to enable multiple channels of voice.  For low cost phones and terminal adapters, the combination of ARM cores with built-in DSP extensions and partner software solutions utilizing this digital signal processing capability enable low cost, low power VoIP implementations.
