At Kyvon dba: ProComm Voice & Data Solutions, we have the refurbished equipment you need. Kyvon nows the legacy equipment because we sold it when it was new. We have refurbished parts for virtually any AT&T, Lucent or Avaya system. Avaya customers, both large and small, have been purchasing refurbished equipment for 25 years.
Do you have AT&T, Lucent or Avaya equipment that you no long need? Please send Kyvon the list of what you have and maybe Kyvon can convert it into credit or cash to purchase what you need.
