Indeed, Averna acquired Calbay System and yes iVVivi did not make it to the web site.
Even though iVVivi is no longer a product that we maintain on a regular basis, we still have the product and people from Calbay are still working with us.
If you are reaching for support, you can always contact Averna support through: https://www.averna.com/en/customer-support/
