Vistula Communications Services Inc., a global supplier of flexible and reliable Voice over Internet Protocol ("VoIP") services to major telecommunications carriers and Internet service providers, announced today that Venezuela's Envox IP, a leading telecommunications VoIP carrier will officially launch a residential and corporate/SOHO hosted IP-PBX, starting October 1st, 2006.

Vistula's V-Cube will be used as the central system to deliver a range of hosted VoIP telephony products to business enterprise customers in Venezuela. Vistula will integrate its web portal set with Envox's existing client and operational systems to give a cohesive client front end. This will facilitate client sign-up and allow those clients straightforward control of their telephony environment.

Envox will offer the Venezuelan market an array of pricing options and packages including a $29 a month plan that offers unlimited calling to the US with a US DID, and bundled corporate products that will include voice, broadband and IP-PBX functions. Additionally, Envox will focus its efforts on the very lucrative call shop market, which is a high growth, high margin business for VoIP telephony in Venezuela. Currently, there are close to 1 million broadband users in Venezuela, all of which are potential clients for Envox.

Envox IP's initial client list includes Banco Federal and a number of major call shop operations throughout Venezuela. Banco Federal will be the first major bank to use a hosted IP-PBX service in Venezuela.

"Banks and financial institutions will be one of the most important markets we will go after," said Jorge Sierra, Executive President of Envox. "We will take full advantage of our first-to-market position to introduce our products to banks, insurance companies, stock brokers and many other corporate clients that have multiple sites."

Rupert Galliers-Pratt, Chairman and CEO, Vistula, commented, "We believe that Envox IP is the right partner for Vistula as we continue to deploy our platform in the South American market. Envox has constructed a high capacity, high quality network that will serve as the launching platform for rapid deployment of Vistula's VoIP product suite. We look forward to working closely with Envox to capitalize on the substantial opportunity that Venezuela provides
