Portico™ Telephone VoIP Adapter (TVA™)

Migrate to VoIP utilizing existing digital (PBX), P phone (Centrex), or analog handsets and existing phone cabling. Advanced VoIP features including IVR and simultaneous ring are delivered to the handset, while features requiring a larger screen are accessed through a browser window.

Citel originally manufactured the P-phone version of its Portico™ TVA™ (“TVA-P”) as a premise-based device, enabling carriers to replace their Centrex system to deliver hosted / cloud or premise-based VoIP services and applications to Centrex telephones already working and in place. As many of the carriers required Central Office (“CO”) functionality, the TVA-P was upgraded to operate in a CO environment so that the devices can be placed at the CO or the users’ premises. With 48vDC a primary source of power at many CO locations a new version of the TVA-P is undergoing regulatory approvals to provide a complete carrier solution.

Obtain VoIP features without the expense or disruption of a “rip and replace” migration.

Enterprises migrate to IP telephony for a number of reasons. They want cost savings. They want to better serve their customers. They want to gain a competitive edge.

But most VoIP migration solutions are expensive, time consuming, and disruptive. They involve obtaining LAN assessments, purchasing new LAN switching gear, rewiring, and retraining. All to support new IP handsets that may not be necessary to obtain the benefits of VoIP. In fact, according to an August 2006 Gartner Research report, an estimated $20.6 billion will be wasted on IP screen phones over the next five years.

The Citel Portico™ Telephone VoIP Adapter (TVA™) changes the dynamics of VoIP migration by enabling enterprises to obtain all the benefits of IP telephony utilizing the PBX telephones and wiring infrastructure they already have in place.

Whether the enterprise is migrating to a Hosted IP platform through a service provider or managing their own on

md_porticopremise IP PBX, Portico simplifies the migration process, and is transparent to most users. With Portico, legacy PBX telephones become new IP endpoints, so replacement simply becomes unnecessary.

The economics of Portico are so compelling, enterprises can justify migration to IP telephony even in the middle of the traditional PBX “buy cycle”. Cost-savings, productivity enhancements, additional functionality, and converged applications are all within reach.

After a fast, simple Portico migration, enterprises on Hosted or premise-based VoIP achieve:

  • Reduced monthly telecom operating expenses through centralized voice mail, IP network utilization, and the elimination of PBX and/or Key systems across the enterprise.
  • Increased productivity through centralization, or even outsourcing, of voice network management combined with enterprise-wide distribution of features and applications.
  • Seamless migration to a unified communications platform.

With so much to gain, enterprises seeking the benefits of IP telephony and convergence have no reason to wait.
