3. VoIP - Overview What is VoIP? VoIP means Voice over Internet protocol.
VoIP is an IP application that provides real time, two-way voice capability in IP over a broadband connection.
Over time, VoIP may offer new products and services not available over the legacy public switched telephone network (PSTN).

4. Why VoIP? Convergence cost savings Scalable Flexible Extensible
You can consolidate multiple traffic types, including IP, voice, video and data over a single network.
Scalable
You have control over services - the “traditional” central switching function is simplified.
Flexible
You receive support for a broad set of services (voice, video, messaging).
Extensible
Enables addition of new applications yet to be defined.
Standards based
IP, UDP, RTP, SIP IETF RFC 3261 thru Various compression mechanisms (G.711, etc), soft client support.

6. Hosted vs Premises-based VoIP
Premises-based VoIP – industry today
Equipment capital investment model:
Requires on-site equipment management expertise and/or outsourcing.
May be cost effective for deployments with a significant density of users per location.
May be cost effective when existing PBX equipment is not depreciated and can be easily upgraded to support VoIP.
Reliability - increases redundancy requirements (cost) for sites that host VoIP services.
Hosted VoIP solution – Qwest market leader
Low capital investment.
Technology protection.
Daily equipment maintenance tasks performed by the service provider.
On-site personnel can focus on providing the best service to the end user.
Cost effective for businesses with multiple geographically dispersed locations and a low-to-medium number of users per location.
Converged data and voice service from one provider with a single point of contact for trouble resolution.
Reliable - intelligence is in the cloud.
Provides an additional level of flexibility that may be hard to achieve with premises- based deployment.
Feature transparency across the entire United States.

Briefly, the new layering in the voice industry has “VoIP Gateways” and IP Transport on the lower layers, with the Gateways providing the conversion and interface to the PSTN, and the IP Transport for the carrying of the voice traffic itself (referred to as “media”). These layers, now very well defined with standard interfaces, have no knowledge of “voice features” or “customer profiles” and hence can be implemented with cost efficient commodity hardware. (This is contrasted quite starkly with the intense complexity of the Class 5 voice switch.)
In this new layering, voice services are implemented on an IP-based “voice applications platform” located anywhere on an IP network, and typically in only a small number of places, enough places for minimize east – west latency, and provide redundancy. This obviously reduces the costs dramatically for rolling out and supporting voice services as compared with the conventional approach of having to deploy voice features end-office by end-office. A voice services approach deployed in this manner can be leveraged for both in-region and out-of-region and benefit both business and consumer customers. This approach also illustrates how the barrier-to-entry to provide “out-of-region” voice services has been dramatically reduced. By acting as a CLEC and merely deploying a VoIP gateway in a local market, voice services from a centralized platform can be offered to customers over a wide array of IP transport. The incremental network capital associated with Voice to support an VoIP endpoint is roughly $50 – this includes the most expensive component of the architecture: the VoIP Gateway. It should also be noted that once the applications platform is deployed, this incremental capital to serve customers is virtually all “success-based” and can be deployed as demand dictates. When combined with IP access offerings for customers that have also have a need for data connectivity, compelling “voice and data” package can constructed for customers.

12. Emergency calling / 911 911 service requirements:
You must have Qwest®-approved customer premises equipment (CPE).
You must have Qwest-approved IP connectivity.
911 calls must originate from the service installation location.
If you do not meet these requirements you will not have access to 911 emergency service.
If you move your IP handset within the service installation location, the 911 service may need to be reconfigured.
Summary: Qwest will provide access to emergency 911 service at the service installation location if you meet the 911 service requirements shown above. If a stationary IP handset is moved, calls may not be routed to the appropriate public service answering point (PSAP).
