"Started strong, but underwhelmed after extended use"
What do you like best about OpenPhone?

Simple IVR system does what I need it to do, apps work decently well on web and android, quite a few features that make it a really great service. Scheduling messages and message snippets are really handy, and I haven't had any issues with call quality.

What do you dislike about OpenPhone?

I switched from Google Voice as a personal user, and have since been dealing with a few of my text messages being undelivered due to "violating carrier guidelines" presumably due to lack of understanding context or treating my personal communications like a business. I don't need to make sure that the handyman who came to my house and told me to text him is on an opt-in list for my messages, and discussing tobacco products with my father in law supposedly violated some usage guidelines. I received no indication that these messages were blocked from the mobile app, only discovering it sometimes weeks or months later using the web interface and trying to figure out why the person never responded. Openphone support has been lackluster about these issues, and continue to simply not respond while their automated ticketing system tries to close out my tickets for inactivity. There is significant lack of parity of features among the mobile app and web interface, so some tasks are impossible to accomplish on one platform or the other. For example, you cannot choose a previously recorded message for your voicemail message from the web interface, but you can from the Android app. Contact syncing seems only possible through costly business-focused utilities like Hubspot, or Google Contacts. Not supporting basic CardDAV contact servers, used by many small businesses, is rather limiting. The workaround is using the mobile app's contact sync, but lately this has become buggy and generates duplicate contacts the longer I let it sit. I regularly have to clear out my entire contact list and allow it to sync again to be usable, otherwise I end up with 5 of every number. Incidentally, you can only delete your full contact list from the web interface. Blocking numbers often still triggers missed call notifications on mobile, so the phone doesn't ring but I still get notified that a blocked number called me... kinda defeats the purpose.

What problems is OpenPhone solving and how is that benefiting you?

I prefer to have a digital primary phone number to avoid the complication of number porting when changing mobile carriers. I also prefer VoIP solutions as they allow me to continue my communications from a computer or other internet connected device even when my primary phone is unavailable.

"Great when it works"
What do you like best about OpenPhone?

Here are my favorite features: 1) The portability is essential for my work-from-home office. My office line is forwarded to OpenPhone so I can take calls from anywhere at any time. 2) OpenPhone allows me to send text messages from my number. 3) Having a local number is great for those who need to call me directly on my OpenPhone line.

What do you dislike about OpenPhone?

The outages are the biggest reason to stay away. In October 2022 multiple outages affected my ability to use the product. I mainly just use OpenPhone to field calls from my office line. However, the outages affected everything so other users would have been in far worse positions than me if their business ran on OpenPhone.

What problems is OpenPhone solving and how is that benefiting you?

I tried Skype and Zoom phone numbers, but they didn't allow forwarding of phone system phone numbers to their services. OpenPhone does this seemlessly with our Mitel phone system.

"An important solution to a problem with good value, great service, and poor software."
What do you like best about OpenPhone?

I like the setup process. It's simple to get started and accurately advertised. It's a well thought out solution to a very real problem.

What do you dislike about OpenPhone?

The software is soooooo buggy. Never been right since I've had it. If I was more of a socialite I could never use open phone. It gets me by.

What problems is OpenPhone solving and how is that benefiting you?

It's an affordable way to have several different phone numbers. If you have several "lives" in various countries, everyone can still reach you because you have a local number everywhere. This thing was made for nomads.

"Used to be a Great Service! But deteriorated recently."
What do you like best about OpenPhone?

Great way to help me distinguish between personal calls and business calls. Also allowing me to have multi-regional phone number for business if needed. Service used to be crystal clear, and felt like if I was using my classic office phone. But recently, there has been delays. Also, I have been getting junk calls/text messages recently as well.

What do you dislike about OpenPhone?

Dislike the lack of possibility to have a three-way call or conference call. Also, would be great to have an auto-attendant feature. If there is, I have not figure out how to use it. Perhaps a user guide would help. Ways to not have as many junk calls/junk texts, and less delays.

What problems is OpenPhone solving and how is that benefiting you?

I have a local phone number which can be used while traveling international. Clients can't tell which country I am in. Also, it's compatible with slack so my team can call me directly from slack, and it will ring on my openphone number, again making it easy to distinguish if it's a business call or personal call.

"Service Degrading"
What do you like best about OpenPhone?

I have been using openphone for approximately 1 year now. The services were great in the beginning. Everything was going smooth. But since the last 3-4 months, i have been facing issues in receiving calls. My clients tell me that they tried to call on my number but it directly went to voicemail. Also, i had problems when i forwarded calls to my cell phone (US) to the number i purchased from Openphone. Directly landing to voicemail. I will be happy if these things are taken care of. Thank you. ericsnyder179@gmail.com

What do you dislike about OpenPhone?

Already mentioned above. I hope you guys take care of the issues.

What problems is OpenPhone solving and how is that benefiting you?

Openphone is helping my business in letting my clients reach me with ease. Also, the interface is simple enough for anyone to understand. Their mobile and desktop apps also works flawlessly and it helps me in dealing with my clients irrespective of where I am.

"Not the best not the worst option"
What do you like best about OpenPhone?

I like that open phone has voice-mail and supports group messaging.

What do you dislike about OpenPhone?

There are often tech bugs and I will often have failed to send text messages. Also calls sometimes echo or will be poor quality.

What problems is OpenPhone solving and how is that benefiting you?

I like that I can have a business number on my personal cell phone that I can give out to clients. It keeps work and personal separate for me!

"Best phone system, but still buggy"
What do you like best about OpenPhone?

An extremely well-thought-out phone system that is miles ahead of Dialpad or Justcall. Miles ahead in terms of UI and usability. Nice touches like multiple options on how to sync contacts on iOS (you can sync them locally without uploading contacts)

What do you dislike about OpenPhone?

No apple silicon support on MacOS, app very slow compared to browser. Serious issues like notification badges that can't be dismissed have gone very long without a fix.

What problems is OpenPhone solving and how is that benefiting you?

An easy to use second phone number and using zapier integrations to automatically welcome people via text when they complete our onboarding.

"Frustrating and too slow."
What do you like best about OpenPhone?

It is convenient to be able to talk right through your computer. It's also a great way to keep in contact with so many people.

What do you dislike about OpenPhone?

Would like to be able to put people into categories. Delete employees that are no longer with us. It's always cutting out in the middle of conversations and continuously dropping calls. It seems like most days it is extremely slow. Sometimes you can't hear anything after you answer the call. Freezes all the time. Sometimes when typing it will jump to another name for no reason. In the middle of using it my screen will go completely white, then needs to be shut down and restarted.

What problems is OpenPhone solving and how is that benefiting you?

I reached out once due to continuous dropped calls. They asked so so many questions and wanted me to send lots of different things and some of the questions I didn't understand. I did not have time for all of the things they were asking me to do/send.

"They can not send SMS Text to any US number and No response to support request"
What do you like best about OpenPhone?

Don't like them AT ALL... wasted time and money to become subscriber. Now my business phone line which has been ported from another good carrier to Openphone (just because they offer slack integration) can not receive or send any SMS text to US numbers. There is no response from them after initial response as they are looking into it. I am stuck without sending text messages to my customers and can not use this number anymore. They charge first for whole year and also to register your number for texting. Worst carrier...!

What do you dislike about OpenPhone?

I don't like this company AT ALL! Beware, they don't seem to be based in US. Support is very poor.

What problems is OpenPhone solving and how is that benefiting you?

They are cheap VOIP option.. but not reliable for a business.

"Buggy interface, lack of customer service"
What do you like best about OpenPhone?

I am updating my review based on my experience using OpenPhone for nearly a year. I have constant dropped calls and issues loading the platform on my PC. I am unable to talk to a real person at OpenPhone regarding these issues so I will be switching to another provider.

What do you dislike about OpenPhone?

Lack of customer services, lack of realiable calls - lots of dropped calls and inability to make calls. I can not trust my business with it. I paid for a year upfront unfortunately but the service is so terrible I will take the loss.

What problems is OpenPhone solving and how is that benefiting you?

I needed a reliable local phone number that connects to my personal phone. This does the trick so I don't have to mix business with personal/family calls but unfortunatly the service is not reliable so I will be consolidating.

What do you like best about OpenPhone?

"The MOST unreliable service out there - cheaper is NOT worth it."
What do you like best about OpenPhone?

The app is laid out well but as much as the layout is nice a lot of the features do not work well or freeze when in use. Desktop version looks great but does not work.

What do you dislike about OpenPhone?

The service as a whole is terrible. I moved over from DialPad and was very hopeful but it has been one disappointment after another. It crashes constantly. It does not load or open on desktop. On mobile is freezes and shows improper notifications. Call quality is terrible. The list goes on.

What problems is OpenPhone solving and how is that benefiting you?

We enrolled with openphone to use as a phone provider for our business that could be used on both desktop and mobile. The service does not work and the never fix anything.

"It's filled with bugs, as a salesperson i keep losing time and money because of this platform."
What do you like best about OpenPhone?

It's affordable and that's all, i can't think of anything else.

What do you dislike about OpenPhone?

It has constant issues, we pay extra for the analytics feature which never works. They keep promising us that it will be fixed in a certain time (1-2 weeks) but it never does, the app stops working randomly. I'm a salesperson and this causes me to not reach my target, I'm losing time and money. You can only talk to a real person of you are a new trial, you talk to sales however when it comes to the bugs, you can never talk on the phone with a real agent.

What problems is OpenPhone solving and how is that benefiting you?

They are not solving anything, they mostly lie about solving the problems and give you random non-answer answers.

"No contact address book syncing makes it unusable"
What do you like best about OpenPhone?

Easy, clean interface. Ability to block spam calls within the app.

What do you dislike about OpenPhone?

The app is unable to use contacts stored on the phone on Android. It tries to force you to rely on syncing with a Google account for all of your contacts. Not using phone contacts is the entire point of a phone app, isn't it? I will not be using a Google account for my business contacts just so I can use this app. This makes the app useless for me, and I already regret porting my number over and paying them $10 a month.

What problems is OpenPhone solving and how is that benefiting you?

Being able to have a dedicated professional business phone line with text messaging.
