I worked as a channel partner for Knowlarity for sometime. Actually I needed a SuperReceptionist account. After experiencing it, I felt many of my friends could buy it as well. They offered me additional commission for referral and I ended up becoming their channel partners.
Product is absolutely rock-solid. Especially when you compare the other garbage in the market. I have never had any problem with the outages and neither did any of my friends I referred and sold the product to.
Knowlarity is a large company now and I have had some problems in their system. Many times things can get lost. However, an email to support gets very fast response so that has become my preferred method now.
