There are few products on the VoIP marketplace that aim to solve a major problem: Completing the difficult transition from TDM (or legacy) telephony to Voice Over IP. After spending a few months with the Portico TVA from Citel, I'm convinced that the TVA is one of those essential products.
With the continued economic uncertainty, companies and organizations need cost effective methods to continue their transition from TDM to VoIP. Now, with the Portico TVA, organizations can utilize their existing digital handsets to connect to SIP-based soft switches or IP centrex systems.
In fact, the Portico supports almost every make/model of digital handset on the market today. Including support for Avaya Definity, Nortel Norstar, Panasonic DBS, and Toshiba handsets, the Portico TVA connects a wide variety of handsets to your SIP environment.
Installation and configuration took around 30 minutes for an environment of 10 handsets. Each digital port can be customized for each individual user, including DSS buttons, ring patterns, etc. The gateway connects to your telephony cabling infrastructure easily, and configuration via the web interface is simple to navigate.
The Citel website breaks out some of the benefits of the Portico TVA gateway:
"An estimated $20.6 billion will be wasted on IP
screen phones over the next five years, according
to an August 2006 Gartner Research report. Smart
enterprises will migrate to IP telephony utilizing
existing PBX handsets and wiring infrastructure.
Legacy handsets are retained until they reach the
end of their effective life, and the enterprise
avoids a questionable investment in rapidly
evolving IP endpoints.
Citel’s SIP-based Portico™ Telephone VoIP Adapter
(TVA™) enables digital, Centrex-compatible
P phone and analog handsets to connect directly to
a premise-based IP PBX or Hosted IP platform over
existing wiring. The enterprise can apply up to two
thirds of its existing telephony investment towards
a new IP platform, dramatically reducing the
expenditure and disruption usually associated with
IP telephony migration. Now enterprises can justify
migration to IP telephony even in the middle of the
traditional PBX “buy cycle”."
