I wanted to ask that you take a look at some of the VoIP telephony software provided by NCH software. We have a whole suite of products that are ideal for home or small and medium sized businesses using voip. our softphone – expresstalk, and PBX – Axon even have free versions making them a good stepping stone as you are starting out with setting up a complete VoIP call management system, that you can always upgrade later. It is completely scalable and customizable simple software solutions. I would appreciate you taking a look at some of our products for possible links or reviews on your website.

Thank you!
