So if you have an Android phone all you will get is a single vibration with NO ringtone. NEED ANDROID VERSION TO RING WHEN CALLED!! ### 1/5 — Customer service don’t follow thru. Ringer sound is quiet *2025-06-24* Customer service said they would send me an email for sms and didn’t. The ringer is only ringing through the ear piece and our calls are very vital to the company to answer them. ### 5/5 — Manager *2024-12-12* The Telzio mobile app has been a huge help for my business. It’s super easy to use and makes managing calls and messages so much smoother, especially when I’m on the go. Features like SMS collaboration and quick access to our company directory have really kept my team connected and productive! ### 1/5 — This app doodoo *2024-11-15* This app doodoo and I need the world to know. Dropped calls constantly, can’t send images, clunky app. It’s actively makes my day worse when in use it. ### 2/5 — Eh *2024-06-07* Probably good if you are an office and just need to forward calls to different offices. Does not allow grouped communications or text conversation forwarding. No ability to track and store analytics by location or type. Lots of bugs on cell phones. Issues if you have vpn. ### 1/5 — The worst *2024-04-11* Honestly, this app is one of the worst I’ve ever downloaded. We use it for work and it’s a nightmare to use on anything other than a landline. Calls dropping or not even going through, do not disturb feature being completely useless, regularly crashes or won’t load at all, now suddenly all of my recordings and voicemails are inaccessible - really great problems to have when you’re using the app for work purposes. If we didn’t use this app for work, I wouldn’t even bother with it. ### 3/5 — Worked great until latest update *2023-10-13* It worked great, I could text & call clients without having to use my personal number. But the new update has messed up the call feature. I go to call & it never connects & freezes the app. Calls can go through the desktop version but not the app ### 1/5 — Update Do not like. *2023-09-28* Coming from us working from a business who uses Telzio app. I use it in my phone because I prefer the phone version more than desktop. Since the update. I can’t no longer see my own moss calls on the app. Nor if I wait to long to place the call on hold or if it’s on hold. It will make the app not clickable. If I push my side button , it will automatically hang up the calls. Which the old version did not do. Some of the new features are great. But the way the update is when it come to call logs etc doesn’t work for me nor when it automatically disconnects my calls. Or when it disconnects from my Bluetooth headphones. Not just me but other representatives here that work with me have the same or similar complaints. Please fix. I do like the company call log directory. But don’t like the function of this new version. ### 1/5 — Useful features *2022-10-25* I am unable to set up do not disturb during non-office hour to avoid getting call at all hours of the night. That was a useful feature that should be added back in. I also noticed that I am unable to delete\clear recent calls. This was a good update but still needs work. ### 1/5 — Update Do not like. *2022-10-13, version 5.0.4* Coming from us working from a business who uses Telzio app. I use it in my phone because I prefer the phone version more than desktop. Since the update. I can’t no longer see my own moss calls on the app. Nor if I wait to long to place the call on hold or if it’s on hold. It will make the app not clickable. If I push my side button , it will automatically hang up the calls. Which the old version did not do. Some of the new features are great. But the way the update is when it come to call logs etc doesn’t work for me nor when it automatically disconnects my calls. Or when it disconnects from my Bluetooth headphones.
