Appendix A: Getting Acquainted with Tenor CMS in the VoIP Network
Service Provider Network
The Service Provider application is used when a company wants to provide reduced toll call access to Enter-
prise customers. The Service Provider provides some form of IP service to their Enterprise customer and now
the Tenor CMS enables them to offer discounted voice services by the ability to install the Tenor CMS unit at
their customer’s location. The Service Provider purchases bulk minutes from their local PSTN provider and
passes the savings onto their customers for long distance and international calls.
Several benefits to a Service Provider application include the following:
• Service Providers get a bigger piece of the convergence market earlier in the game.
• Reduction of PSTN access costs with savings passed along to the customer.
• Improved long-term customer retention through integrated, competitively superior offering.
• Rapid deployment of a money-making multi-point VoIP network.
• Hassle-free installation, excellent remote manageability.
