  1. Open your mind to a beating heart of IP Herman Abel Product Manager Aculab (stand 515) herman.abel@aculab.com Phone: +44 1908 273815

  2. Agenda • Benefits of VoIP • Challenges of VoIP and how they are addressed • VoIP application example • Key technologies for success of your VoIP project • What comes next? • Q & A

  3. Benefits of VoIP • How could VoIP affect your business? • Reduce operating costs • Simplify infrastructure, create flexibility • Broaden range of services • Increase productivity and staff efficiency • Increase customer satisfaction

  4. VoIP challenges Support various service and equipment types Choice of signalling protocols Security Quality of service (QoS) Reliability and availability

  5. More VoIP challenges Billing and reconciliation Network interconnection Call routing and number plans DTMF, tones and telephony events Firewall and NAT traversal Supporting OSS/BSS

  6. … and even more VoIP challenges Regulatory issues: • CALEA - lawful interception • E911 - emergency and operator services Fax and modem support Bandwidth utilisation Migration path

  7. VoIP challenges addressed Reliability and availability Quality Network interoperability Legacy support Knowledge VoIP matures – ready for mainstream deployment!

  8. Example: contact centre • Types of contact centres: • One site • Multi-site • Distributed • Virtual

  9. Virtual contact centre - benefits • Highest flexibility for change • Easily scalable • Lowest OPEX, low CAPEX • Global 24/7 availability, multilingual support • Flexible working hours for staff • Best customer experience

  10. Virtual contact centre - architecture

  11. Virtual contact centre - requirements FeatureFunctionality

  12. Virtual contact centre requirements (2) FeatureFunctionality

  13. Virtual Contact Centre - Converged Architecture

  14. Value proposition VoIP enables – media processing delivers!

  15. Building blocks for ‘3-in-1’ solution Available in hardware and software: • DSP-based IP media processing cards • Large scale solutions, voice channel counts up to 1200 per card • Requires minimal resources from host machine CPU • Easily scalable, redundant • Host media processing (HMP) software • Small scale solutions (up to 240 voice channels per server) • CPU performance dependent Media processing IP core TDM VoIP

  16. Building blocks functionality Which functionality is a must? 1. IP core based, full VoIP Quality of service: RSVP DiffServ Control and signalling: RADIUS SIP / SDP H.323 MEGACO / H.248 / MGCP NAT RTP / RTCP CODECs Security FAX IAX Media:

  17. Building blocks functionality (2) 2. Support full TDM legacy • Multiple E1 / T1 trunks • CODECs support and conversion • G.711, A-law/μ-law • Signalling methods • Euro ISDN, Q.SIG, CAS, CCS • SS7 protocol • With integrated MTP, ISUP, SCCP and TCAP

  18. Building blocks functionality (3) 3. Support enhanced media processing resources DTMF detection and generation Music on hold Call recordand playback SVI Speaker Verification and Identification TTS Multilingual text-to-speech Conferencing / call mixing DSP IVR Interactive voice response VAD Voice activity detection ASR Audio speech recognition Enhanced echo cancellation FAX Rx / Tx Noise removal and generation

  19. Building blocks functionality (4) • Low cost per channel • Highly scalable • Operating system support (Windows, Linux, SPARC Solaris) • Runs on standard chassis (PCI/cPCI/PCIe) • Remote management capabilities (SNMP) • Easy to migrate and enhance

  20. What is next? Convergence • Multimedia contact centres • Video-based IVR • MoIP - converged messaging • Fixed - mobile convergence • IMS • IPTV

  21. Q & A Q1: Is VoIP technology quality on par with a standard PSTN network? A: At least. In many aspects VoIP exceeds the quality provided by PSTN. Q2: Why do you need an IP core based media platform? A: Only IP core based platforms enable the creation of truly scalable solutions. TDM core could be scaled to some extent, but with much higher cost.

  22. Q & A (2) Q3: Why do you need SS7 functionality? A: Yes, but only if these resources come with no additional cost. Some vendors do charge for media processing resources. A: PSTN is here to stay for at least a decade. You need to provide service for traditional phone users too. Q4: Do more media resources lead to better ROI for your systems?

  23. Summary • VoIP technology provides tremendous opportunities for your business • Media processing is the ‘ACE’ of VoIP • TDM legacy must be fully supported • Highly integrated systems provide significant ROI Functionality Customer satisfaction ROI
