The VZ.VoiceHQ includes a full assortment of field-proven voice processing and call management software.  By basing the VZ.VoiceHQ on the ZSP400 architecture, solution developers can include advanced voice technologies, e.g. AMR-WB, that dramatically improves quality without impacting BOM.  Unlike other IP Phone designs that use low performance CPU processors, the VSI403LP architecture provides best-in-class DSP performance as well being well equipped to tackle traditional host and system processing. Some examples of the VZ.VoiceHQ software offerings include AMR-WB (G.722.2) as well as G.722.1 and G.722, Narrowband/Wideband Acoustic Echo Cancellation, and SIP authentication with static call forward to a specified PSTN number.

VeriSilicon, a market leader in the VoIP market with its ZSP400 architecture, has developed the VZ.VoiceHQ platform, combining an unprecedented number of features that uniquely addresses the product and cost requirements for the evolving IP Phone market.  Developers may lower the system BOM, by selecting a single processor system, VSI403LP, without sacrificing functionality.  The award winning ZSP400 is able to run all the necessary VoIP functions as well other application software such as SIP and RTP.  Alternatively, developers can select a dual-processor option utilizing the ARM7-based NXP LPC2378 to handle non voice tasks and other feature customizations that could be required.
 
Voice developers may choose from a number of solution options for the VZ.VoiceHQ platform. The reference design, software, and silicon are available from VeriSilicon, and respective development partners, enabling fast time-to-market.  Alternatively, developers may also license the ZSP and voice software stand-alone or enlist VeriSilicon Turnkey Services for a customized VSI403LP offering.
