OpenPhone vs MightyCall

What is OpenPhone?

OpenPhone is a business communication VoIP provider that integrates calling and messaging services. The service allows professionals to build, smooth out, and automate their workflow. According to Crunchbase, OpenPhone was founded in 2018 and has its headquarters in San Francisco, California. Its primary clientele is in the USA and Canada.

What is MightyCall?

MightyCall is a cloud-based call center software solution for small and midsize businesses. It offers advanced customer service and sales tools, and, on top of that, excellent VoIP services. Established in 2013, the company is located in Wilmington, Delaware. With MightyCall, businesses can track their agents’ activities and interactions with clients and improve the overall success rate of campaigns.

Key differences between OpenPhone and MightyCall

Of course, two companies can’t provide identical services; they must have certain differences. Let’s compare MightyCall and OpenPhone features and see which one prevails.

Types of Numbers

MightyCall offers 3 phone numbers, and you can choose from local, toll-free, port, and existing numbers for free. This flexibility allows businesses to establish a local or global presence and adjust to specific marketing strategies or customer bases.

OpenPhone provides local numbers and supports toll-free numbers but does not offer vanity or international numbers. This may limit businesses trying to build a more global strategy.

International Calling

MightyCall makes it easy to connect businesses with its clients and partners worldwide. Whether you’re expanding your customer base, managing international teams, or staying in touch with global suppliers, MightyCall ensures smooth and reliable communication beyond borders. This can be done by buying an international virtual number. However, it should be noted that each international call is subject to per-minute rates.

OpenPhone works a bit differently from MightyCall. You can’t acquire an international business phone number; you can enable international calling for one of the numbers you already have (within the US or Canada). This option also comes with additional per-minute rates. Technically, this sounds like an easier option. However, it should be noted that if you want to make a call to, let’s say, Germany, clients will be more inclined to answer to a German phone number.

Interactive Voice Response (IVR)

MightyCall features a customizable multi-level IVR system. This system allows businesses to create call flows and route calls to the appropriate departments or agents, increasing the level of customer experience and overall operational productivity.

OpenPhone offers IVR (phone menus) capabilities, but they are available only in the Business plan. This could be an obstacle for businesses with budget limits.

Call Monitoring

MightyCall provides different live call monitoring features. These tools allow supervisors to oversee and assist agents in real time, improving training and customer service quality. Let’s have a bit of a closer look at these features.

MightyCall’s Live Call Monitoring feature gives supervisors the ability to oversee calls in real-time, ensuring quality service and providing instant support to agents. With this tool, supervisors can listen to ongoing conversations, offer guidance, and step in when needed to quickly resolve issues.

Here are the different ways supervisors can monitor calls with MightyCall:

• Call Listening: The supervisor listens in on a live call without interrupting or being heard.
• Call Barging: The supervisor joins the conversation and speaks directly with the customer.
• Call Whispering: The supervisor provides guidance to the agent during the call without the customer knowing.
• Call Intercept: The supervisor takes over the call completely, disconnecting the agent and continuing the conversation with the customer.

Unlike MightyCall, OpenPhone does not offer live call monitoring features, which may limit a business’s ability to supervise and support its customer service teams effectively.

Dialer options and AMD

MightyCall makes outbound calling as simple as possible with three powerful auto-dialer options, designed to maximize efficiency and organize agent workflows:

• Preview Dialer: Gives agents a moment to review call details before connecting, helping them prepare for more meaningful conversations.
• Power Dialer: Automatically dials numbers in sequence and instantly connects agents to live calls, reducing wait times and keeping campaigns moving efficiently.
• Predictive Dialer: Uses smart algorithms to anticipate agent availability and optimize call pacing, ensuring maximum productivity.

Additionally, MightyCall includes built-in Answering Machine Detection. This feature ensures that agents are only connected to live recipients, helping to avoid wasted time on voicemails.

Unfortunately, OpenPhone doesn’t offer any of MightyCall’s options, making the process of outbound calling campaigns manual.
