What our customers say

Schöffel Sportbekleidung GmbH

"With software from estos, we were able to integrate the home office transparently and enable our employees to interact better and more directly – with each other as well as with customers and suppliers: Softphone, presence management and the connection to Dynamics NAV, these are the highlights for us."

Manfred Gruber, Head of IT

AUGUST STORCK KG

"Being able to make calls independently of the office phone via softphone client is a great convenience: Thanks to ProCall Enterprise, calls no longer have to be diverted to external devices; employees can be reached and make calls via the office number – regardless of where they are working."

Malte Rudolf, IT-Service, Head of IT Infrastructure & Support

Barmherzige Brüder charitable sponsors GmbH

"Always available on the same number – with ProCall Enterprise: I set up call forwarding for my extension in the office to forward calls to my smartphone. Our employees who work from home use softphones with headsets or the mobile app for their mobile phones."

Michael Wieser, IT Area Management
