The Ooma Office mobile app can be set up to ring whenever someone dials your Ooma Office number or extension.

Easily transfer calls to another extension, to your work voicemail, or to a coworker’s voicemail.

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.

Still glitchy but continues to improve

I would have given less stars for functionality, but the customer service at Ooma is one of the best I’ve ever received. I use iOS for this app, and a Windows PC at work. This app is far from perfect. Pros: incredible concept, well priced, great customer service, many features work perfectly. Cons: App is slow, does not access customer names that were entered on the computer. The app does not consistently update the time and date that a phone call or text was received. Often it shows yesterday when it was two or three days ago. Deleting old voicemails is slow and sometimes difficult. Do not let this review stop you from using Ooma phone service. I love this company and they have helped my small business provide quicker response time and better customer service to my customers!
