What is OpenPhone?

OpenPhone is a VoIP solution that aims to make it easy to get a separate phone number for work. To keep using an existing work number it can be ported over at no cost.

The advantages of the OpenPhone basic voice functionality, as provided by the vendor are:
  • Keep personal numbers private - No more spam calls on a personal phone number.
  • Works on existing devices: No need to get a new SIM card, carry two phones, or be tied to a desk.
  • Get started in under a minute: A team can be up and running with a new business phone numbers almost immediately.

The solution also helps to make it easy to determine whether a call is a personal or business call, and helps to maintain a work life balance. For users in a team, calling features (incoming call identification, set business hours, contact ownership information to associate an incoming call to a teammember, etc.) help keep call responding more organized.

Users can also send any desired material to share with a customer over SMS through OpenPhone, including GIFs, videos, or other kinds of files. It also supports group messaging, and autoresponders. OpenPhone can be connected to 3,000+ applications via Zapier also, so less time need be spent writing and managing these.

OpenPhone also provides Contact Management features, enabling the user to:
  • Import your contacts - Sync Google Contacts to OpenPhone.
  • CSV import: Import contacts instantly via CSV
  • Zapier: Connect with any CRM or data source via the Zapier integration.

Data can be organized to present a single source of truth for contacts, and contacts can be associated to a preferred team member, or details of a contact can be sent to a teammember so that they can provide support. Contact data can have custom properties and fields, details and notes, or mentions of teammates to share these details.

For teams, OpenPhone numbers can be used as a shared inbox, where one number is shared across multiple phones (i.e. teammates). Internal correspondences are supported with direct messaging between teammates, available through OpenPhone. Presence and status features let teammates (or customers) know who is available, and when. Also, both the Premium and Enterprise plans support round robin routing for teams.

Local calling (US & Canada) is unlimited across all subscriptions, while international calling is also at varying rates. For all plans, SMS calling is available via Zapier at a rate 1c per message. The Enterprise plan offers extended features over the Standard and Premium plans, such as an Audit log, analytics, and Enterprise plans receive priority support.

OpenPhone has been widely used by businesses and professionals to streamline their communication processes and enhance customer interactions. One of the key use cases of OpenPhone is its ability to distribute inbound calls and messages to appropriate departments with almost instant success. This feature has proven particularly valuable for organizations that receive a high volume of incoming calls or messages, as it ensures that customer inquiries are directed to the right person or team efficiently.

Users have also found great value in integrating OpenPhone with other software tools such as CRM systems and Zapier. This integration allows for a seamless flow of information between different platforms, enhancing communication capabilities and improving overall productivity. By leveraging features like call history, call log, in-app texting, and call transfers, users can effectively manage their conversations and ensure no important details are missed.

OpenPhone is also utilized by small businesses in specific industries such as real estate and law firms. For instance, a small real estate business benefits from having a single business phone line through OpenPhone that encompasses various modes of communication including voice, text, graphics, and photos. This not only facilitates efficient communication with clients but also assists in organizing and keeping track of important property-related information.

Many users appreciate the integrated experience provided by OpenPhone, as it combines voicemails and texts within one app. This eliminates the need for separate applications and streamlines communication management for busy professionals. Additionally, the web interface offered by OpenPhone proves convenient for those who prefer using a full-size keyboard for texting or need to access their business phone line on their computer.

Another notable use case of OpenPhone is its application in recruitment processes. Companies have successfully utilized OpenPhone to chat with job seekers and tag them with relevant information, make phone calls directly from the app, and organize all relevant information in one place. This streamlines the hiring process and enables effective communication with potential candidates.

Furthermore, OpenPhone serves as the primary business line for many companies, allowing them to communicate with customers through text, calls, and other features directly from the mobile app. This comprehensive communication solution enhances customer interactions by providing a seamless and efficient channel for inquiries, support, and sales.

The call tracking capabilities offered by OpenPhone have received significant praise from users. The ability to record conversations for later reference and seamlessly integrate with other software tools has proven valuable for businesses looking to track and analyze their communication data.

In summary, OpenPhone is highly versatile and caters to a wide range of industries and professional use cases. Its easy-to-use features and seamless integration capabilities have been praised by franchisees who credit OpenPhone for bringing their business to the next level and surpassing other phone service providers. The law office industry is another sector where OpenPhone has found significant traction, with many law offices using it as their sole phone service provider for all telephonic communication purposes. OpenPhone's reliable and efficient features enable these law offices to direct business calls effectively and maintain clear lines of communication with clients.

Additionally, OpenPhone has been appreciated for its ability to share the responsibility of answering calls in a law office without a dedicated customer service team. This allows multiple team members to handle incoming calls and ensures that no call goes unanswered, resulting in improved customer satisfaction and quick response times.

The flexibility and adaptability of OpenPhone make it an excellent choice for businesses of all sizes and industries. Whether it's managing inbound calls, integrating with other software tools, organizing conversations, or enhancing customer interactions, OpenPhone offers a comprehensive solution that meets the diverse communication needs of modern professionals.

Clear and Intuitive UI: Several users have praised the call routing SMS and text management system for its clear and intuitive user interface. They have mentioned that the UI is great and really intuitive, making it easy for them to efficiently use the system.

Useful Range of Features: Many reviewers appreciate the wide range of features offered by the system. These include call recording, IVR, voicemail recording, and a full history of calls and texts. Having all these functionalities within a single platform has proven to be useful for their business needs.

Integrated Texting System: The integrated texting system has received positive feedback from users. They liked being able to send and receive texts directly from the app. The ability to use emojis and mark messages as unread adds to the system's functionality, according to reviewers.

Integration Limitation: Some users have found the integration with HubSpot to be one-way, which has limited their ability to fully utilize the software's capabilities. They expressed frustration at not being able to sync data between the two platforms seamlessly.

Improvements Needed in Follow-up Setting: Several users have mentioned that setting and marking follow-ups could be improved, suggesting that this feature is not as intuitive or efficient as they would like it to be. Users feel that there should be more options for customizing follow-up reminders and scheduling.

Lack of Lead Stage Setting: Many users have expressed a desire for the ability to set lead stages within the software, as they believe it would greatly benefit their workflow and help them better track their sales process. This feature would allow them to categorize leads based on where they are in the sales pipeline.

We use OpenPhone daily to chat with job seekers and help them get interviews. Each user gets their own phone number that allows them to text job seekers, tag them with information, make phone calls, and organize all of the information that we have. It's been a huge help for us in organizing and integrating pretty well with HubSpot.
  • It's great for texting.
  • It's great for making phone calls. You get a new, unique phone number and can text/call from phone or desktop.
  • UI is great and really intuitive.
  • Integration with HubSpot - it doesn't talk both ways with HubSpot.
  • Setting and marking follow ups could be much better.
  • Allowing us to set lead stages would be a huge improvement for us. Things like, called, not interested, bad number, follow up, closed, etc.
  • Showing analytics like the time when most people respond, answer calls, etc would be super helpful.
We're a small team that runs pretty fast and loose. The UI is great and seems to be scaling well with us. Our users all pick it up very quickly and do most of the things that we need it to do. I can't really say if it would be a good fit for an enterprise team.

OpenPhone is the application we use for our phone system. It is the only phone system we use, and we use it for all incoming and outgoing calls. OpenPhone has many useful attributes, such as being able to upload our own recorded greeting, call history/call log, marking calls unread, in-app texting, and call transfers. We use all of these features in-depth.
  • In-app contacts list
  • Call transfer
  • In-app messaging between team members
  • Pricey
  • Cannot transfer out-going calls
OpenPhone is good for small businesses. It has a detailed call history and call log, and allows users to mark messages as unread to track which issues have been resolved. However, it can get pricey if there are many team members that need to use it. Furthermore, we cannot transfer outgoing calls between team members, which complicates our usage.

Internet telephony, VOIP, and other IP Voice solutions have been around for some time. Vendors are in abundance too. When it comes to deciding which solution would provide the best experience, the choice can be daunting. The reason (if you're like me, are reading these reviews) is that in many cases the solutions available, can be rebranded, or resold options all claiming to be feature-rich. With such a broad spectrum of solutions, to rise to the top of a category in such a short time shows the elegant simplicity of a complex and reliable communications tool. From limits to proprietary equipment, prerequisites, or complicated pricing tiers, an IT admin almost needed another admin just for this. OpenPhone allows both at my company, and others I've talked with as well, to distribute inbound calls, messages, and more to appropriate departments with almost instant success. One of my favorite features is its integrations to a CRM, and the ability to go beyond even that with Zapier and more. If for any other reason than to redirect spam and other time expenses, this solution will win.
  • Call Routing
  • SMS and Text Management
  • Customer Support
  • Clear User Interface
  • Reliability
  • Broader CRM Integration options
  • 24/7 Phone and Chat Support
  • More Device, Microphone, Video support
If you have more than 2 people in your organization, then this will save you so much time. Delegation is the key to starting a business. Even when you're a 1 person show, being able to present to your user base the differentiation of options for client communications is critical. As a founder, feeling compelled to be always on is something I strive not to be. OpenPhone gives you that flexibility. I have found it to be less appropriate in complex HIPPA compliant areas, but that is it. OpenPhone really does seem to suit an open array of use cases.

I use OpenPhone to provide a single business phone line for a small real estate business. It provides me with voice and text service, including graphics and photos which some competitors can't do. The integrated experience is also refreshing! Why should voicemails and texts be separated into separate apps? With OpenPhone they are combined. The web interface is super convenient since I like to use a full-size keyboard when possible for texting.
  • Virtual phone number
  • Text/voice integration
  • Web interface
  • Haven't found any shortcomings yet
OpenPhone is a perfect tool for my needs, providing a reliable 2nd number with a reliable, and extremely easy-to-use iPhone app.

OpenPhone is the only phone service provider we use at our law office. We use it for all telephonic communication purposes.
  • User friend interface
  • Integrated texting system that is fully functional (e.g. allows us to "unread" messages, use emojis)
  • Allows us to store contacts within the app
  • Full history of calls and texts
  • Allows in app texting between team members
  • Random bugs would occur at times (e.g. one account on one phone would ring while another account on another phone would not, despite sharing the same work number)
  • Inability to transfer outgoing calls, despite call transfer being a premium feature
OpenPhone is well suited for small businesses where team members need a simple to use, yet robust telephonic system.

OpenPhone needs a better call transfer system that allows transfer of outgoing calls.

We use OpenPhone as our primary business line and it works excellently. We are able to utilize our existing mobile phones and solely download the OpenPhone APP which is incredibly convenient. You can also text, call, and do a variety of things directly from the Mobile APP to communicate with customers.
  • Ease of use, setup, and interface
  • Texting directly from desktop OR mobile APP. Works on both.
  • Call Recording, IVR, voicemail recording, the whole 9.
  • Call quality can be spotty on wifi if the connection is poor, but nothing they personally can do about that. 4G LTE is usually stronger and more stable.
  • N/A honestly excellent product for the price.
OpenPhone is phenomenal for small businesses regardless of how many employees or users. If you're a one-man show, OpenPhone is great. If you're a small business with 25 employees, OpenPhone is still phenomenal. The more employees and lines you have, the easier it is to collaborate and communicate with one another. I would say it may not be as efficient for massive companies that are expecting crystal clear call clarity every call. But as long as your 4G or wifi connection is strong, you won't have any issues.

All of our business calls are directed through OpenPhone. We don't have a dedicated CS team and OP makes it easy to share the responsibility of answering calls.
  • We love that it transcribes and sends an email of the transcription.
  • records all calls
  • ring on multiple phones
  • can use our personal phones for it, but distinguish between business and personal calls.
  • It would be nice to have it ring a few times for 1 user and then waterfall to other users if the first person doesn't answer.
We are a 3-person team and it works well for our purposes. I'm not sure at what point we will outgrow it.

Call tracking is incredible with this. OpenPhone records conversations for your reference later allows automatic text and integrates with many other softwares. OpenPhone has brought our biz to the next level. All of our franchisees love it. We've tried Grasshopper, Google Voice, and many others. None do it as OpenPhone do it.
