Challenges of Delivering Rural VoIP (SP-04)
What is the compelling reason to offer VoIP? High cost of entry into VoIP..
Technical staff learning curves Expected return on investment Class 5 Legacy issues
Poor voice quality & reliability of VoIP transport.. Access gateways, E-911, LNP, 1-800, Operator Services Costs to upgrade network to provide expected high QoS
broadband access - what flavor DSL?
Rapid technology evolution – life cycle?
Telcos’ core business shifts from POTS to IP services carried on ultra-broadband PIPES…….POTS-To-PIPES (P2P)
People moving off ‘wireline’ as a must have connection• Cheaper LD with VoIP and Better mobility with cellular
Directions – Existing Telcos
Telecom Evolution for Rural VoIP
New signaling protocols will be more effective than existing AIN and ubiquitous (SIP)
Corporate sponsors will pay for transport, offer free public phone calls
listen to a 15 second message from the sponsor IXCs role will change
IP centric QoS transport, network management, Core network application service providers and LECs will
prosper if IP enabled LECs will benefit by providing transport access and specialized
applications at the network edge. Local peer to peer switching,
Core applications for network intelligence; E911, routing, LIDB,

VoIP TerminationCarriers
• Regional traffic stays in region• Avoids backhauling
• LD routed to maximize profitability• Ability to maintain Access/Termination fees
• Backhauled cost reduced via IP• Local Gateway Utilized for pure LD plays

Trends in Long Distance Voice Transport
Voice over Internet becoming extremely inexpensive means to transport voice and data..
Long distance commoditized, charges becoming inconsequential…or zero
Commercialization of voice transport, “free ride” • Sponsors pay for transport• Users pay for access.
New DWDM technologies will continue to keep supply of transport high and prices low.
Bandwidth expanding rapidly Inherent QoS improvements for VoIP
Innovative applications leveraging embedded intelligence in IP and PSTN gateways..
Applications readily customizable for specific client needs Pay as you go for specialized access and features / utility Video conferencing will lead way to Video over IP
But, Do not overlook Basic Engineering Requirements
Network Engineering is critical for VoIP to deliver expected QoS to subscriber

Other Rural VoIP Challenges
1) VoIP results in bypass of access/termination fees Use existing CLASS 5 and TDM Carrier terminations
2) 911 service to VoIP subscribers must be provided Configure system to use existing PSAP connections Outsource E911 management available for VoIP
3) DSL speeds are a big factor in VoIP quality Low speeds in the 120kbps range do not support VoIP protocols that take
up to 100kbps VoIP can be compressed to a lower quality 33kbps SIP based DLC/DSL can also solve VoIP bandwidth issues, and reduce OAMP
and backhaul costs 4) Rural carriers must deal with TDM, ATM and IP networks
Operational cost of technical resources, infrastructure components & test/diagnostic equipment
Consider solutions that evolve to a pure IP network infrastructure 5) PSTN subscribers are dropping in the USA
VoIP dial tone service includes CLASS and V/M features @ 1/3rd the Price Cellular services can be bundled w/PSTN and VoIP to attract users New SIP enabled “sticky” services retain customers
Compelling Reasons to deliver VoIP
Competitive offering to prevent subscribers from changing service to “Vonage” type, IM type, VoIP
Access to IP- LD networks for reduced operating costs, and customer retention..
Supply and Demand – Economics of high supply of IP bandwidth
Technology obsolescence – VoIP will reduce overall value of legacy transport systems to basic commodity.
Relocation of network intelligence to the core and edges of the network to provide revenue generating applications.
Potential “Sticky” services
Ringback Tones
Create a globally recognized BRANDED ringback tone
Revenue generating• Subscribers customize
sounds from your content
• Subscribers utilize ring interval to deliver personal voice messages.
• Provider of Subscriber uses interval as advertising time.
ARPU = $1-3/month service fee plus per tone cost
* Average airtime of 9 sec
express yourself with…
Find me Follow me
discover smart tracking with…
Links locations and telephone devices to a single Directory Number and optional Voicemail
TDM and IP terminations.
Subscriber can change terminations.
Can be offered as part of a VoIP dial tone service or independently.
Inbound only or bi-directional.

minutes… meet you at
the door
I’m already here…you’d better hurry, it’s getting
busy
Hi guys, I’m leaving

Customer can seamlessly moves calls between Wi-Fi / VoIM / VoIP / PSTN, and cellular networks
Cellular network never takes control of the call Auto Leap..QoS triggered Leap Can be one number/ one voice mail
By 2007 85% of all cell phones sold will be dual mode.
