Mobile App better than my last VOIP servce

Love the texting feature. Calls and texts Work well over cellular. This makes it worth it. I wish App had control to Ooma Office & we could set the call handling from the app. If you are in a meeting, you have to log out not to get calls. A simple Do No Disturb to go straight to voice mail would be great. Also, If you are the admin and there are 2 numbers, you have to continually go back and forth to each box or you miss texts and messages. Not good -so we only give out the 2nd ext number but that defeats the purpose of routing the call. The Auto attendant is just passable and I hope Ooma realizes this and offers more features in the future. I also feel they have future plans to improve and do listen to their clients. Great customer support so far too. And, Ooma is much better than the Grandstream App and is definitely a must have if you need affordability, mobility and can handle the work arounds you might have to make for your business.

Great App for Professionals On-the-Go!

I’ve used the Ooma Office Mobile App for over a year now and my overall experience has been great. It allows me to keep my business calls separate from my personal calls, all while using my cell phone. With the app, you get a separate business phone number along with business phone features like a Virtual Receptionist. The app notifies you when you are receiving an Ooma Office call, so you know to answer in a professional manner. The texting feature also just became available so you can even send messages from your business phone number! This app is great for professionals using their cell phones for business calls, without having to give out your personal cell number.

The iPhone app does not have all the features

I recently switched my business phone service to Ooma because of the text message feature. However, I now learned that this feature is not available on the iPhone app. My assistant has an Adroid phone and the app on her phone is very different and it has a lot more options and features. I also do not get all the voicemails and they are sometimes rerouted to the wrong extension.
I posted the above review in December 2019z
However, in late January iPhone had an update which in fact fixed all the issues it previously had. I can honestly say now that I am very happy with the app.

Developer Response ,

Hi Lawchick608 - text messaging is available on both iOS and Android versions of our apps. For the most part, both (iOS and Android) apps are identical. In fact, iPhone app is a little ahead in terms of available features. I suspect that your extension may not be fully configured, hence, there could be a discrepancy between what you see and what your assistant is seeing in the app. If the issue is still present, please contact our Customer Support or email to us directly at so we can help. ^Kind regards, Dmitry
