Objectives Confirm our understanding of what host media processing is and is not Allow us to identify when it should be selected Save time by learning some top tips

Agenda What HMP is and is not – a definition How will host processing technology affect me? Where it is good for – market sectors Experiences and top tips Q&A Summary

Traditional DSP technology IVR application Minimise interactions with host processor Well defined set of performance criteria Highly scalable

DSP (TDM) based IVR architecture TDM speech T1/E1 IVR application Host PCI bus Real time Near real time RecordPlay File store Real time switch and conference

HMP (IP) based IVR architecture IVR application Real time Near real time RecordPlay File store HMP server NIC Voice over IP LAN

HMP and DSP technology fit Simultaneous channels IP TDM Media processing functions Traditional DSP hardware (analogue connection) Traditional DSP hardware (digital connection) Host media Processing (IP connection) Host media Processing (IP connection)

Criteria for selecting HMP You are looking to develop an IP application Your application requires o Play o Record o DTMF detection o Speech processing You are targeting low density, cost sensitive markets

Criteria for selecting HMP You can see an opportunity to re-use your application for this market space using: o The same API o Integrated IP protocols o Knowledge from your vendor

Early experiences and top tips Start with understanding the architecture o Check how the proposed elements will fit Viable to re-use existing IVR applications o Check the product uses the same API It can be challenging – it’s new! o Check you can work closely with your vendor o Make sure you’ll get direct vendor support
