What is HMP?
• HMP is now viable• Faster roll out of features• Riding the consumer wave rather than the
specialist wave
January 23-26, 2007• Ft. Lauderdale, Florida
Why HMP?
• Key advantage – it’s software-based– Flexibility and speed of deployment– Channel counts– No hardware
• Cost efficiencies• New application opportunities
January 23-26, 2007• Ft. Lauderdale, Florida
What applications can be based on HMP?
• All traditional applications– Voicemail, IVR, conferencing, broadcast, contact centre,
etc.
• New IP-centric applications– Free from TDM and hardware constraints

What to look for in an HMP product
• High channel counts per standard processor• Simple pricing and licensing structure• Choice of operating system• Compliance with IETF standards• Not restricted to a particular make of
processor
January 23-26, 2007• Ft. Lauderdale, Florida
What to look for in an HMP product
• Protocol support – SIP, H.323• Wide portfolio of codec support – iLBC, G.711,
G.729AB, G.726, G.728, GSM-FR, etc • Choice of operating system• Comprehensive set of media processing
resources• Security – Secure RTP, TLS, SIPS, NAT
traversal

HMP in a mixed TDM/IP environment
• How should your HMP-based solution connect to the TDM network?
– Add a TDM telephony card– Gateway
• Key considerations– What are the implications for my solution?– Will it allow me to take full advantage of the
benefits of HMP?– What flexibility will it afford me?

Summary
• HMP is viable– Flexibility– Cost efficiencies
• For today’s mixed TDM/IP market– Use a gateway and leverage the advantages an HMP-based
solution can bring– Integrate into existing card-based solutions
• Hardware versus software – it is a deployment choice• The future holds some exciting developments for
host-based media processing
