Case Study

Technology Brief

White Paper

  • Enterprises strive for service excellence to win new accounts and to serve existing customers, establishing long-term purchasing loyalty. The contact center, as the focal point of communications, is a strategic asset in achieving this goal. Customers have ever-rising expectations of service quality, and enterprises need to invest heavily in systems and staff to meet their demands. An alternative for these enterprises is outsourcing, in which some or all of the contact center operation is managed by one or more third-party organizations.
  • Although many enterprises are eager to deploy converged voice and data applications and services over IP, they see their legacy PBX systems and upfront costs as roadblocks to the enhanced capabilities that IP would bring. This paper demonstrates that legacy PBX equipment does not have to be replaced for enterprises to begin a phased migration to IP convergence. Dialogic® media gateway appliances make the implementation of IP technology in PBX systems possible right now, and with low upfront investment costs.
  • Successful Voice over IP (VoIP) deployments can deliver solutions that provide voice quality that is comparable to traditional circuit-switched telephone networks, but at a lower cost. Builds on the background information provided in Overcoming Barriers to High-Quality Voice over IP Deployments.
  • This paper supplies high-level and detail comparisons and a set of scenarios to help you decide whether an appliance gateway, gateway subsystem, or HMP interface boards are the appropriate option for an environment and for a particular set of development resources and deployment needs.
  • This white paper provides an overview of some of the XML communication technologies that address new customer expectations for a more media-centric, information-rich caller experience, and briefly discusses Dialogic® products that leverage XML technology.
  • This white paper briefly describes the T.30 and T.38 protocols and compares traditional fax technology with Fax over IP (FoIP).
