VoIP - Carrier Hosted Voice Service (CHVS) "Advantage"

Voice over Internet Protocol (VoIP) is a comprehensive, communications solution that addresses local, long distance and international voice and data solutions through a single network. It allows customers to integrate voice and data applications by converging these services over VITA's contracted IP network.

CHVS VoIP Advantage provides a migration path to VoIP by offering the option to use the customer's existing legacy voice solutions, deploying IP phones at the desktop or use the MSN Messenger client on PCs and laptops. This is referred to as Hosted IP Centrex (HIPC). When using IP phones, customers may eliminate their PBX or CENTREX connection and obtain routing and features from the VITA's network, providing a low-cost alternative to purchasing and managing on-site voice equipment.

Features and Benefits

  • Support for traditional features such as dial plans and range privileges
  • Advanced calling features, including find-me routing and selective call acceptance
  • IP-to-IP and IP-to-PSTN calling
  • Local origination calling from certain markets and access back into the local networks for call terminations, including operator services, directory assistance and 911
  • Long distance calling
  • Ability to maintain current PBX and phones and/or migrate to standards-based IP phones
  • Administrative control through a Web interface


Unified Communications as a Service (UCaaS) VoIP services and Enterprise IP voice services are available to Commonwealth agencies through two products UCaaS, and CHVS-HIPC. Both products offer a hosted VoIP service, however the UCaaS provides a foundation for the addition of new services to support broad agency needs.

UCaaS VoIP services provide a foundation for full-featured voice services from standard telephony up to Call Center and Video over IP services providing an advantage to Commonwealth agencies over the CHVS -HIPC service. UCaaS provides all the benefits of a VoIP service, leveraging the VITA MPLS investment and addresses key Commonwealth needs:

  • To leverage the MPLS network investment
  • An opportunity for statewide coverage not restricted to local telephone carriers
  • To centralize the service delivery from the CESC and SWESC facilities allowing incremental growth of the core system spreading the investment across many agencies and sites versus the purchase and installation of individual site based systems
  • To lower long distance expenses
  • Phone service redundancy, providing service in the event MPLS connection is lost
  • To incrementally invest in a high quality IP based voice infrastructure where new services can be added on demand to meet the Commonwealth's business needs, these include contact center / call center, rich media conferencing and unified presence

Key benefits of UCaaS to the Commonwealth

  • Carrier-grade reliability using Cisco's industry-leading Call Manager VoIP platform
  • Easily-scalable service allowing capacity to be added as the user population grows
  • Common voice service across agencies for all agencies on MPLS
  • Ability for agencies on end-of-life phone systems to migrate to a monthly RU based service model avoiding upfront capital and one-time installation charges
UCaaS network based features UCaaS offers outbound calling features which can be tailored to the Commonwealth's enterprise standard. These features require line identification are available only to locations in which the local phone carrier supports line identification service. The following table summarizes the features available to each UCaaS Service.
Attended Call Transfer Allows a user to announce a caller or consult with a third party before transferring the call. This feature is also known as "Call Transfer with 3rd Party Consultation."
Call Blast– Personal Enables multiple phones to ring simultaneously. For example, calls to a user's desk phone could also ring the user's mobile phone. The first phone to be answered is connected. When already on a call, users can choose whether other simultaneous devices ring.
Call Forwarding Enables phone service to be set to forward the call to a user selected phone number.
Call Return Enables a user to call the last party that called, whether or not the call was answered, by dialing a feature code. The system stores the number of the last party to call, and connects the user to that party. Users can also execute call return via the UCaaS Communications Manager.
Calling Line ID Blocking Enables a user to block delivery of his/her Calling Line ID when making outbound calls.
Calling Line ID Delivery Enables the delivery of inbound CLID or phone number.
Consultation Hold When the call is answered, the user can consult with the add-on party. To drop the add-on party and reconnect to the original party, the user depresses the flash hook twice.
Direct Inward/ Outward Dialing Users are assigned a 10-digit directory number that can be used to place or receive calls directly, without forcing access via a central number.
Do Not Disturb Allows users to set their extension as unavailable so that incoming calls are given a busy treatment.
Extension Dialing Enables users to dial other members of the group using extension numbers.
Flash Call Hold Provides call hold functionality from any phone. It enables users to hold a call for any length of time by flashing the switch-hook on their phone and dialing the respective feature code. Parties are reconnected again when the switch-hook is flashed and the feature code is dialed again.
Last Number Redial Enables users to redial the last number they called by clicking the 'Redial' button on the communications manager screen or by dialing a feature code.

Comparison by Tier

Conferencing Meeting Center Price Comparison

Below is a sample comparison of the three pricing options an organization of 200 people has that is interested in Meeting Center data conferencing. In this sample comparison, the three pricing options have similar total monthly fees, but provide different benefits. When evaluating pricing, customers must determine the usage patterns of their organizations to determine the pricing pattern that will best fit their needs. It is recommended that customers use several months of conferencing data for evaluation of minutes used, who is using the minutes, and the number of conference attendees. The price breakdown below is meant to illustrate differences in options for similar price points. These rates do not include audio conferencing, which is a separate service.

Named Host: A fixed seat is assigned to those who host or initiate each meeting or support events. This seat agreement allows each named Host plus 14 additional attendees to participate (total of 15 attendees). This option is better for organizations that will ordinarily use a single trainer or facilitator to host all meetings.

Concurrent User: The number of concurrent users (attendees) purchased is shared between a number of hosts designated by a site. These hosts may not exceed the maximum number of concurrent users available under the seat agreement. This option is better for organizations that will ordinarily have multiple or constantly rotating meeting facilitators.

Pricing options

Per-minute agreements 200 users x 100 average monthly minutes x $.202 = $4,040 (variable based on usage) Any number of conferences (each conference host must have a per-minute agreement) 500 unlimited
