SIP Trunking Is Key to Accelerating Unified Communications Deployments

White Paper Published By: Sprint

Companies today are undergoing a significant transformation to a more global Anywhere Enterprise. Unified communications (UC) is a crucial component in this evolution and organizations look to collaborate better with an extended enterprise (see Exhibit 1 on the next page). UC has the power to help companies lower the overall cost of communications, bring worker productivity to new levels, enhance corporate green initiatives and completely redefine the way we work by becoming part of our application infrastructure. However, the deployment of UC is not without its challenges. Too often, organizations go down the path of deploying new technology with old technology principles in mind and UC is no different. Many of the early adopter deployments of VoIP and UC were designed exactly the same as the old systems, severely limiting the overall value of UC, which is a highly flexible, IP-based solution.

SIP Trunking Is Key to Accelerating Unified
Communications Deployments
by Zeus Kerravala, Senior Vice President | February 2009
Executive Summary
Companies today are undergoing a significant transformation to a more global Anywhere EnterpriseT. Unified communications (UC) is a crucial component in this evolution and organizations look to collaborate better with an extended enterprise (see Exhibit 1 on the next page). UC has the power to help companies lower the overall cost of communications, bring worker productivity to new levels, enhance corporate green initiatives and completely redefine the way we work by becoming part of our application infrastructure.
However, the deployment of UC is not without its challenges. Too often, organizations go down the path of deploying new technology with old technology principles in mind and UC is no different. Many of the early adopter deployments of VoIP and UC were designed exactly the same as the old systems, severely limiting the overall value of UC, which is a highly flexible, IP-based solution.
Migrating from traditional trunk lines to SIP trunking is a very simple, cost-effective change to open doors to other advanced services that can enhance a UC deployment. SIP trunking will allow companies to recognize the following benefits:
. Dramatically lower the overall cost of communications
. Extends UC to software-as-a-service (SaaS) applications and other cloud-based options
. Accelerates UC deployments through the simplification of network design
. Easier migration to other advanced services such as mobile integration and MPLS networks
This report introduces the reader to UC, outlines the benefits of UC and highlights some of the challenges in deployment. The report also introduces the reader to SIP trunking and how it can play a key role in accelerating the deployment of UC as well as provides recommendations on how to evaluate SIP trunking providers and some thoughts for initial deployment.

I. Introduction UC consists of the following communications tools:
Organizations have torn down their corporate walls and are . IP telephony/VoIP: VoIP enables companies to use the moving toward Yankee Group's vision of becoming an Anywhere corporate data network for phone calls rather than having Enterprise. That is a global company that is networked together and a dedicated network just for telephone service. Historically, comprises a variety of constituents. Employees, partners, suppliers VoIP was considered by many organizations as the foundation and customers are all important components of an Anywhere of UC. However, during the past year presence and desktop Enterprise for virtually anytime, virtually anywhere access to people integration have been elevated to being critical to the success and information. And their need to communicate faster and more of UC. collaboratively ov... [download for more]
