The best thing about Net 2 Phone was that it really helped us manage our calls in an effective way! It also had great customer services which were always available for help whenever we needed them!! I don't have any dislikes as such but there are some things like not being able to send files via email or using VPN connections etc., however these aren't major issues at all since they're quite easy fixes when you know what's required from their side :) We used this software mainly because its very reliable and efficient with call management & tracking capabilities too! Plus no one could ever say anything bad against this product!!
