HMP- Host Media Processing
– HMP is the movement away from proprietary expensive hardware
– To promote scalability we will continue to rely on DSP’s in high volume call scenarios for voice quality and compression
– DSP’s must be low cost, standards based and performance based (programmable)

Signaling / Homologation
• SIP, SS7, PRI/BRI, analog• When connecting to a carrier, signaling
certification is frequently required.• Certification/conformance testing is expensive
and time consuming• Why would I spend time and resources to certify,
then provide these certifications gratis
