I get calls from people and when I click to call them back, 9 is not automatically added so I get a failed call and have to manually redial the number. ### 4/5 — Great App *2024-08-15, version 9.8.112* First, you can make calls from ANYWHERE in the world with WiFi and they’re billed by your work provider as if you are calling from your desk. You can forward phones from one extension to another with this App no matter where you are. It is possible to turn off receiving work calls on your cell. If people are complaining about call quality or dropping it’s likely the WiFi they are using at the time. I love this App! ### 2/5 — Great concept, needs improvement *2023-11-28, version 9.7.117* This app is great in theory and has all the things I need to utilize in order to use my cell phone for work related calls, however, every person I contact reports terrible sound quality resulting in me needing to call them without using the app. This does change based on using Wi-Fi or cellular data, the sound quality remains an issue. ### 3/5 — iPhone has to re-register *2023-07-31, version 9.7.114* App works for a few days to a week and then fails. Keep getting message that can’t register. Great business app if this glitch can be fixed. ### 1/5 — Ridiculous *2023-04-27, version 9.7.25* Absolute mess. Not ringing, asking for headphone to be added to call. So you do and still can’t hear the client. Use wifi, use data nothing! Please fix it this is my work and I don’t understand how it can work for months then break. Calls stuck and won’t end. Constant issues. ### 1/5 — Absolute rubbish *2023-04-26, version 9.7.25* If any business are considering this, don’t bother. The most unreliable piece of rubbish, constant call failures, always shows ‘registration lost’ and doesn’t ring. Junk ### 3/5 — Will Call You Even If The App Is Closed *2023-03-22, version 9.6.159* This app is great for work purposes, it has good sound quality and dialing is fairly easy. However, this phone app is terrible for work life balance if you are required to have it on your personal phone. It will push through EVERY call even if it’s during non-work hours. Even if you mark yourself as out of office, in a meeting, on vacation, or do not disturb, or close the app, phone calls will get pushed through to you anyways. The solution is to completely log out of the app, butIt would be nice for the statuses/availability to not actually disturb you. if I am setting my work hours are in this app, it should understand those work hours as the ones to call during. If I’m on vacation, the app should not push calls through. ### 1/5 — Worst app *2023-02-14, version 9.6.159* This app is horrible and doesn’t even serve its main purpose, to be able to answer the phone when you’re not at your desk. RINGCENTRAL is lightyears better than this. ### 3/5 — iPad support *2023-01-20, version 9.6.159* Please update to support horizontal viewing with iPad ### 1/5 — It’s awful *2022-12-06, version 9.6.159* Absolutely can’t stand this app, eats my battery like nothing else too ### 1/5 — Terrible *2022-11-18, version 9.6.159* Why would you want to be able to place a call from your desk phone miles away and not hear anything from within the app? I had people in the office telling me they could hear my speakerphone at my desk in use while I was attempting to use the app - who wants that? Why is that even a feature? ### 1/5 — Very hit or miss *2022-07-20, version 9.5.17* Sometimes works ok but more often will be unable to answer calls, will drop calls, people will call me and it won’t ring etc. ### 1/5 — Garbage *2022-05-31, version 9.5.17* Have to keep reinstalling for it to work properly, avoid if you can. ### 1/5 — Can’t make calls from cellphone *2022-05-20, version 9.5.17* I’ve been using this app for the past year and it was working well for what I needed. The new version seems to have removed the option to make a call from my cellphones. It restricts options to make direct calls or from the base phone. I need the app to let me call using my cellphone. ### 1/5 — Useless - Don’t Install *2022-03-29, version 9.4.109* I tried setting this app up for my office phone number. Setup was easy but when I tested this app, it doesn’t display any notification when the phone number is receiving a call. I only get a notification after I missed the call. What use is this?!?!? ### 4/5 — Missing potential *2022-02-24, version 9.4.109* Great app. Most of not all issues people experience is nothing to do with the app but the phone service provider. Would be great if you could control ring group membership by status as I keep forgetting to add myself back to a ring group when back in the office. ### 1/5 — Terrible *2021-12-03, version 9.4.20* The mute button freezes. So when I’m on a call and on mute I can’t get off mute without quitting the app (leaving the call) and restarting the app. Has cost me minutes and time on some really important calls. How does a button jam on an app? Terrible design. ### 1/5 — Continuous problems, don’t recommend *2021-08-15, version 9.3.111* The phone randomly rings all the time “Re register”. The calls don’t connect half the time when you answer. Currently the the soft phone won’t even connect “registration failed” My company is now finally moving to another phone system. ## Most critical reviews (10 lowest-rated) ### 1/5 — App Never Works *2025-05-08, version 10.0.107* The app is generally useless. It struggles to connect and simply spins most of the time—particularly since the most recent update. ### 1/5 — Huh? *2025-04-07* Is there any way this app can stop sending me work calls? ### 1/5 — Sad *2025-04-07, version 10.0.105* Our CFO made us use this app for our phone system. It’s terrible. You’d think the IT Dept would have done some due diligence before signing off on it. Sad. ### 1/5 — Terrible App *2024-10-30, version 9.8.206* 99% of incoming calls go straight to voicemail. Can’t make an outgoing call so just I end up using my normal cell line. ### 1/5 — Not usable *2024-10-04, version 9.8.205* I can’t even get this started because it refuses to connect, whether I scan the QR code or type in the key. I’ve tried several times. This app is a brick. ### 1/5 — Barely works *2024-06-19, version 9.8.102* Sometimes the app doesn’t ring when you get an incoming call if your phone is locked or you’re in another application. The call overlay won’t work until you open the app so you can’t answer a call coming in. Frequently incoming calls get stuck in “IVR Connecting” after answering and result in a missed call. Frequently the app will just not ring at all and a missed call notification will just pop up. If you use an ACD line sometimes you will just get put into a different Aux state than available for no reason. Mitel support is basically non existent; and that’s thrice as true for this abandonware. Update 6/19/24 My softphone just stopped working with no configuration changes today and the performance continues to get steadily worse I can’t believe this company charges for this product when we’re basically having to suffer through such awful use issues. ### 1/5 — Barely works *2024-04-02* Sometimes the app doesn’t ring when you get an incoming call if your phone is locked or you’re in another application.

I call approximately 15-20 leads every day with this app on my iPhone. Sometimes more. There are so many occasions when external calls fail and don’t go through. Internal and external incoming calls mostly ring once if I’m lucky and even if I try to answer, the call fails. I would not recommend using this application at all. I feel it’s a complete waste of time. You’re better off paying for a separate phone and plan for business calls. The amount of problems I have with this, I know I’m missing business opportunities because it’s so unreliable. ### 1/5 — Just the worst *2023-08-30, version 9.7.114* My company uses this and it’s the worst phone system I’ve ever used. App hasn’t worked for me for 6+ months. It won’t let me log in. Or just sits on load for ages. In the office and at home it constantly has issues. If I dial out on the soft phone there’s no sound, it won’t go through my work phone. All calls need to be forwarded to my mobile. Apparently we’re stuck in the contract for some years but don’t use it!!!!! ### 1/5 — Unuseable *2023-06-26, version 9.7.31* Terrible connection then drops the call after a few minutes of trying to understand what the garbled person on the other line is saying. Pointless app. ## Most praised reviews (10 highest-rated) ### 5/5 — Huh? *2025-05-07, version 10.0.107* Is there any way this app can stop sending me work calls? UPDATE: Works great! All my calls get sent directly to voicemail. Thanks, MiCollab! ### 5/5 — Great App! *2023-02-21, version 9.6.159* This works great to be able to use my cellphone as my work phone. Haven’t had any issues like the other bad reviews… ### 5/5 — Great Application *2021-03-31, version 9.2.155* I have used MiCollab for Mobile for many years now on iPhone and find it to be a great and reliable application. Great for travelling around the world and always having access to my softphone and UC applications. ### 5/5 — Works perfectly after updates *2020-09-18, version 9.1.375* After the latest update and the patch applied on server all functions now working. ### 5/5 — MiCollab Mobile App *2020-01-27, version 9.1.8* Great UC app bringing my full office UC experience to my mobile device. With Softphone active, I can handle all my calls effectively and also have great features in using the feature rich Chat. Very cool 👍 ### 5/5 — Great app and love new look! *2019-10-18, version 9.0.34* This version finally corrects some issues I’ve had in the past and my chats are synchronized across all devices! Love the refreshed new look! ### 5/5 — Great App *2019-02-28, version 8.1.112* This is a really great app. Calls work well as well as chat. The menus being hidden on the side is a little strange but it is functional. ### 5/5 — Great Unified Comms Apps *2018-04-05, version 8.0.306* Works really well, flawless softphone usage and a very “ joined up” feel to the UI. ### 5/5 — Works great with my Mitel phone system *2017-05-25, version 7.3.106* If you have a Mitel phone system then all you do is login and you now have your phone and messaging with you on the go! ### 5/5 — Beautiful UI - lots of features *2016-02-20, version 7.0.164* Nice update.... Much cleaner than MiCollab 6. Mobile first design approach. Use it all the time when I'm not in the office. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/). User reviews are verbatim App Store reviews.
