Pentti Kumpulainen from SCANTEL GmbH Wednesday, November 27, 2013 #10961 I have worked with many call center solutions before (Genesys, Avaya, etc.), and I have to say that none of these come even close to what these guys have to offer. Our agents and managers simply love the simplicity & reliability of LeadDesk! 3 of 4 people found this review helpful. Did you find this review helpful?
