I like that it allows me to have multiple phone lines, which is something my previous provider didn't allow for (the only other option was unlimited mobile plans). The interface could be more intuitive - some of us are not tech savvy so navigating around can sometimes feel overwhelming! It's one less thing we need as our office grows in size/complexity; previously managing all those landlines would've been difficult if at times there were over 20 people working from home simultaneously or needing access outside normal business hours due their work commitments etc..
