The ease of use across all platforms as well integrating with our legacy system was really great! It's also very easy from within an application too add or remove numbers/lines without having users log into another site is nice!! No dislike at this time but do listen when contacting support about features you need not currently have available - they can be helpful by suggesting other solutions which may fit your needs better than what we already offer (or vice versa). We've been able solve problems using predictive analytics capabilities like trends analysis where before there would always seem so much noise between different calls coming through any given day causing mis-detections etc.
