Out-Tasking Managed Business Voice Services

Executive Summary

New converged infrastructures allowing voice, video, and data to be transported over a single network are changing the pace of business communications. The convergence of voiceand data offers organizations unmatched cost savings, along with greater resilience and enhanced productivity. Businesses are finding new voice services more important as theymeet the challenges of supporting increasingly remote workforces and additional locations. As a result, they are looking for an easier and cost-effective way to deploy and manage integrated voice and data communications systems. These challenges are addressed by managed business voice services, which include business phone services, site-to-site voice,unified communications, and Public Switched Telephone Network (PSTN) access. Business voice services can now be out-tasked—taking advantage of a service provider's convergedinfrastructure.

Out-tasking enables a business to focus on its core competencies, while taking advantage ofthe expertise and dedicated staff of a service provider. Interest in out-tasking managed business voice services is steadily increasing as organizations take note of the resulting costbenefits and flexibility. According to a study commissioned by Cisco Systems® in late2002, 65 percent of businesses planning to implement IP Virtual Private Network (VPN)capabilities are interested in out-tasking, as are 55 percent of those deploying IP telephony. The study found that cost reductions can be significant—enterprises out-tasking managed converged IP networks are saving 25 percent or more in network and communications expenditures.

Managed business voice service providers bring their customers the latest technology, along with network management and monitoring capabilities that are available around the clock—24 hours a day, seven days a week, and 365 days a year. Service providers offering managed business voice services bring solutions tailored to meet an organization's particular requirements, from providing a complete communications network to complementing traditional private branch exchange (PBX) capabilities with new IP PBX technologies. Quality of service (QoS) can be implemented across all network components, such as LANs, routers, and firewalls, helping to further reduce overall expenditures.

Finding the right business voice solution for your organization begins with assessing and prioritizing your unique requirements, as well as becoming informed about your alternatives and some important decision points. This overview provides a starting place. More in-depth information is available at:

Market Overview

A fast-paced, networked economy has broadened the range of business communications tools to include voice, data, and video. Organizations seeking to enhance productivity and reduce costs are looking at their communications options, including high-speed and converged networks. For many businesses, however, the cost of retooling their existing network infrastructures is prohibitive. For this reason, organizations are out-tasking their business voice requirements, turning to service providers who already own the infrastructure and the expertise to implement and offer managed business voice services over a converged network. Service providers are offering reliable, secure solutions, enabling organizations to lower costs and increase productivity.

Business alternatives offered by service providers range from out-tasking an entire IP network to operational management of IP equipment to provisioning of specific telecommunications services. Regardless of the configuration that meets your organization's needs, business voice services deliver consistent superior voice quality and network reliability.

Types of Services

Service providers offer end-to-end converged network services to organizations of all sizes worldwide. Service offerings typically include business phone service, site-to-site voice service, PSTN access, unified messaging, and enhanced IP services. In addition to networked communications, service providers can provision, monitor, maintain, and troubleshoot business voice infrastructures.

Business phone services—Business phone services are the subscriber and group calling services that are provided to businesses depending on their needs. The service includes basic dial-tone and direct-inward-dialing (DID) assignment. A company that requires a full-featured IP PBX would use a Cisco CallManager solution. A small business could solve its needs through a Cisco CallManager Express Services solution, providing a "keyswitch-like" solution.

Site-to-site voice—Site-to-site voice enables an enterprise to call from one of its sites to another site over the service provider's voice over IP (VoIP) infrastructure, further reducing long-distance costs. The service enables the enterprise to maintain its own private dial plan, including support for abbreviated extension dialing.

PSTN access—Access to traditional circuit-switching PSTN networks may be enabled locally from your own VoIP gateway or centrally over a managed service provider network. Central PSTN access provides economies of scale, which, in turn, reduce business costs.

Unified communications—Unified messaging capabilities allow workers to access and immediately respond to voice, fax, and e-mail messages from any phone or PC within the organization. When deployed on a converged network, unified messaging supports a universal "inbox" containing messages in all types of communications media. Unified communications capabilities, such as rules-based call routing and speech recognition, further enhance and streamline business workflow.

Remote network operations—Managed business voice services can include IP telephony, customer premises equipment (CPE), network management, coverage of remote sites and workers, configuration management, and any moves, adds, or changes.

Voice-over VPN—Business voice services can be enabled on VPNs, securely supporting teleworkers and mobile operations by providing access to critical information and communications.

Enhanced services—Once businesses implement or out-task an IP network, they can take advantage of certain advanced services. These may include custom IP phone Extensible Markup Language (XML) applications and in the future, IP customer contact services and IP conferencing. Organizations can take advantage of the XML programming language to easily download critical information and customized applications to a user's phone. Service providers can now deliver customized, revenue-generating, premium XML applications to their business voice services customer base.

Business Requirements

As organizations seek cost savings in a low-margin economy, managed business voice services offer a viable avenue to reduce expenditures. Managed business voice service providers bring lower support costs for intersite connectivity, simpler capacity upgrades, and the efficiencies of converged network solutions. But cost savings are not the only advantage of managed business voice services—network performance can be improved across vital productivity parameters, including higher availability and bandwidth, lower latency, and high-quality remote access.

Focus—Out-tasking business voice services allows an organization to focus its workforce, infrastructure, and IT resources on core business capabilities and strategic initiatives, while using the expertise and advanced technologies that a reliable service provider can bring to the table.

Managing risk—Managed business voice services enable organizations to respond quickly and efficiently to unpredictable events, with provisions for disaster recovery and rapid workforce changes. Service providers bring dedicated resources and up-to-the-minute technologies to security monitoring.

Cost savings—Reduced calling charges, such as toll charges for intra-enterprise voice traffic, are the most obvious day-to-day gain for businesses, but savings in infrastructure, management, monitoring, and productivity efficiencies can also be significant. Monthly fees replace large upfront infrastructure or rewiring investments. In addition, teleworker support costs are lowered. Managed business voice services allow organizations to perform at lower costs, bringing a quick return on investment from networking technology investments. Lowering total cost of ownership (TCO) directly affects profitability.

Increased productivity—Flexible communications solutions that support several business models are having a positive impact on productivity and creating efficiencies. A few examples—mobile workers and telecommuters can securely and quickly access business communications networks; all types of media (voice, video, and data)are available over a single high-speed network; and interchange between business locations is smooth and efficient.

Flexibility—Because new business voice services consolidate all data types across a single network, organizations can choose the configurations that meet their requirements and can adjust service models quickly and easily. Solutions are available for all business models, from the single-office to distributed enterprises, to help transition over time.

Scalability—Business voice service consumption can be directly correlated to usage requirements. Migration can be scaled down to a "one phone at a time" implementation model, if desired.

Integration—Integrated data and voice solutions support secure, high-speed broadband access.

In-house control—Out-tasking managed business voice services does not have to mean relinquishing control over critical businesses processes. A managed services provider can work with you to help you maintain control of workflow in your organization. Businesses with in-house IT expertise can determine where control is desirable, and where service provider support can free up time and resources to be devoted to widespread infrastructure management and strategic business initiatives.
