CHAPTER 15 & 16 Service Provider VoIP Applications and Services Advanced Enterprise Applications

Service Providers: Cable companies Telco companies Wireless companies

Service Providers Needs: Carrier-class reliability and salability A shared platform for all subscribers-multitenancy Reduction of operational expenses

Subscribers Needs: Robust feature functionality Multimedia, predictive dialing, speech recognition, automatic call distribution (ACD) Full administrative control Rapid deployment Powerful intergration with CPE

Service Providers Applications: Microsoft Communicator Microsoft NetMeeting Cisco IP Phone PC-based softphone VoIP Integrated IM clients

VoIP Advantages: Equipment use and call control capacity are dynamic The distribution of call control logic and intelligence is more transparent and easy to manage The use of signaling resources is efficient Device provisioning and updates are done in a production environment and are simpler then similar work in PSTN Adding new features and applications over time is easy Remote-management and third party control are simpler because network resources are shared across applications

Case Study; Prepaid Calling Card: Subscriber purchases a prepaid calling card The card is activated through a RADIUS server Client uses a Number TFTP server provides automated prompts Client dials number to be connected to Billing computer correlates the called number (CDR) costs with amount on pre-paid card When pre-paid card has no credits the call is terminated User can add credits to the card

VoIP Peering Issues: Resolving numbering/dialing plan issues Interoperability issues on protocol standards and implementations Privacy and security issues with caller identity and validation, caller-ID call spoofing, voice spams….

Consumer Fixed Mobile Convergence (FMC): Can connect via broadband, cellular or public Wi-Fi Users are mobile through each system Connection to the PSTN via service provider

Consumer Fixed Mobile Convergence (FMC): Benefits

Migrating to VoIP: Phased migration Legacy PBX – VoIP QoS Cisco Unified Communications Manager

Enterprise VoIP Benefits: ROI Toll-bypass Applications  Click-2-Call  Microsoft NetMeeting  Cisco IP Phone  Cisco IP-based Softphone

Advanced Enterprise VoIP Benefits: Voice and Video Conferencing WebEx Set-up and manage meetings Join and Leave meetings Tones and announcements when attendees join or leave During a conference View a list of participants Share and view documents Allow text messaging (IM) Record store and play back conference

Presence-Aware Services: Buddy list on phone Call routing using availability features Enhanced missed call features Availability of users for ad-hoc conference Camp-on service Click-to-dial applications Enhanced contact center applications

Wi-Fi Enabled Phones: Calls get seamlessly switched from broadband, Wi-Fi, and cellular networks Cost savings from moving away from cellular networks

Better Voice Quality: Wide-band CODECS Adaptive multi-rate CODECS Robust against packet loss
