So much hassle to use

It does work....if you can work out how to jump through all the many and never ending hoops they present you with. The accompanying on-line software is not intuitive at all with a similar bewildering controls you must first master. The app, the on line software and the desktop integrator appears to have been written by 3 groups of people that at no time had a meeting to make sure they were all on the same page! This is woefully short of what we have come to expect these days. I am convinced the good reports on here were paid to write that! I am a real user. Also just to add to my annoyance there is no Apple watch support!

Very buggy for a tech app

I’ve been using VOIP for years, at least 15 years now anyway and I had hoped by now that providers could supply interfaces allowing users to go about their daily business without throwing their phones at the wall every 5 minutes.

In some regards, this app works well...we have multi lines coming in, easily identified etc. But, there are bugs on iOS when you select a previous caller from the list ...sometimes it’ll call them, sometimes it’ll just hang. Other issues include selecting a contact from your iPhone contacts....the only option you have is to view the iPhone contact but it defaults to the first alphabetical contact on ones list meaning one has to manually type in a recipients number and ultimately add them to your horizon contacts.

Bit slapdash to be honest. My 14 year old nephew could whack up a more reliable interface.

Completely disregards phone settings

I never write reviews, however this one needs it. I downloaded this for work and it consistently ignores my phones “do not disturb while driving” and constantly rings through while driving and when “do not disturb” is on, no matter the time of day. I then turned off the notifications for the app so I can have a meeting without it ringing, bc then it rang through regardless. What’s the point in having an option to turn the notifications off if the app is going to completely disregard this?
