SANTA CLARA, Calif., August 29, 2007 - VeriSilicon Holdings Co., Ltd. (VeriSilicon), a leading world class ASIC design foundry and silicon solutions provider, announced the VZ.VoiceHQ application platform targeting the rapidly growing IP phone market.

VeriSilicon and its solutions partner, Encore Software Ltd., have combined an unprecedented number of features into the VZ.VoiceHQ platform to address the product and cost requirements for the evolving IP Phone market. For lowest BOM, developers can select a single DSP processor system based on the ZSP400 architecture to run all the necessary VoIP functions as well other network-layer and control software such as SIP and RTP. Alternatively, developers can select a dual-processor option that would include the ARM-based NXP LPC2378 to handle non-voice tasks and other end-product features that may be required.

• G.711,G.729AB,G.723.1, G.726,G.722,G.722.1,G.722.2
• G.168 Line Echo Canceller
• DTMF Detection / Generation
• Call Progress Tone Generation
• Narrowband AEC (8-128 ms)
  
• Call Progress Tone Detection
• Caller ID Generation/Detection
• Voice Activity Detection(VAD)
• RTP/Adaptive Jitter Buffer
• Comfort Noise Generation
• Comfort Noise Generation
• Packet Loss Concealment
• T.38 Fax Relay
• T30 / Group 3 Fax Support

All the above software modules run on the ZSP400 processor and corresponding reference silicon (including VSI403LP, VSI403US, VSI407LP, VSI407US) and include advanced voice technology, such as AMR-WB and AEC/WB.

The VZ.VoiceHQ supports a broad number of user features that one would expect for an IP Phone. For example: originate/terminate SIP voice calls, Caller ID display, call blocking/hold/retrieve/waiting/mute, 3-party conference, speakerphone, remote configuration, instant messaging.
