The most important thing I like about it is the ability to make calls from home or mobile devices without needing a landline or cellphone. Being able to do this makes life so much easier when you work long hours and don't have access to your office phone system. It can be slow at times and you might need to restart it a couple of times to get everything going right. Sometimes we loose connectivity during peak call hours and it takes a while for it to come back up again. Also, sometimes incoming calls will keep ringing until your voicemail picks it up. This is one of those purchases where it was well worth it because we no longer needed to use a landline or cellphone to attend our meetings. I love the ease of use. It is intuitive and very easy to set up and manage my network. It is a great tool to keep my network safe. I do not have any dislikes. I love the customer support too. If you want to keep your network secure and protected this is a great tool to use. I like that it is easy to use and has many functions to keep my network safe. I am able to access my network from anywhere. I can also monitor my network from anywhere.
