The 10 Mobile VoIP Providers You Should Consider for Your Business

Top10.com Staff
Mobile VoIP features can enhance your business
What exactly is mobile VoIP, how can it support both small and enterprise level businesses, and what are the trends to keep on top of to stay ahead of the game? With the help of some of the best mobile VoIP providers in the country, we’ve outlined everything you need to know to make smart choices for your business needs.

What is Mobile VoIP?

With the rise of remote employees, video conferences, and 24/7 business needs, mobile VoIP offers business owners and staff the same VoIP functionality they use at the office, on their mobile or handheld devices. This is typically provided through a dedicated app, and while many people are familiar with this technology already, even if they are not consciously aware of the fact.

Think about apps like Skype, or WhatsApp. It is likely that you use one or both of these on a regular basis. But when it comes to mobile VoIP with some of the top US providers, you have to think bigger to get a true understanding of the potential benefits.

The simplest way to imagine mobile VoIP transforming your business is in creating a mobile office. Think about the common tasks and interactions which take place in your physical office space: mid-day conferences, collaborative chats, IT support issues, and customer service requests. Mobile VoIP is increasing its functionality all the time to encompass these features into a fully portable system for communication and collaboration.

Popular Features of Mobile VoIP

Mobile VoIP has come a long way since simple voice calls over the internet. Here’s a look at the many features that can benefit you and your business:

  • Link separate offices. If you have more than one office, this is a great way of creating a seamless working environment between them. It also helps alleviate time differences for global workers, as staff can take calls or meetings from home or on the move. Check with your provider to see if it offers PBX capabilities, helping you create a private branch exchange for your staff, not only for all of your physical offices, but also on mobile.
  • Appear ‘always on’. Working hours can become a thing of the past when your mobile phone is also your office phone. Any time a customer has a query or a concern, they have a direct line straight to the correct staff member. VoIP providers allow users to create extensions and groups of extensions so that calls can be routed effectively. If your business wants some downtime, you can also create personalized voicemails or greetings which explain opening hours or redirect accordingly.
  • Conferencing. Conferencing capabilities are improving all the time, and can include video chat, instant messaging, and a conference floor monitor system. This last tool allows admin to manage invitations to meetings, questions coming in, and options like muting certain members.
  • Screen sharing. This means that IT support or other colleagues can see your problem or example at a glance from their own screen. Mobile VoIP also allows for video and file sharing, all over the internet, and without a third party middleman.
  • CRM. Customer relationship management tools which can be integrated into the top business VoIP solutions include Salesforce, Act, Zoho, Microsoft Dynamics, and Oracle. These allow you to keep track of your customer data, your incoming and outgoing calls, capture call notes, and explore real-time accountability.
  • Integrations: Whether it’s customer service, office staff or teleworkers, your business deserves to get the most out of its employees. Your business VoIP can support this, with integrations with popular productivity software such as G-suite or Office 365. Amongst others, Salesforce Desk and Zendesk can support customer service, while software such as Clio or ConnectWise are great for business management.
  • Security. Security is paramount when it comes to business VoIP, both for mobile and desktop. The latest trends in security include powerful ID authentication tools, end-to-end encryption, and Transport Layer Security (TLS) or Secure Real-Time Transport Protocol (SRTP) encryption.
  • Professional look. For small businesses especially, having your business number routed directly to you wherever you are is priceless. Some companies allow you to create unique local numbers around the globe, so that your customers always feel that you are a professional local presence for them. Whether your user is calling from Japan or Australia, they will be able to use a unique local area coded number to call your mobile directly.

Mobile VoIP Quality and Performance 

The biggest concern that customers have when it comes to mobile VoIP is reliability. This is key when it comes to the image of your business and your interactions with both customers and staff alike. 

While free mobile VoIP services, or those intended for personal use, may include issues such as latency errors or weak signal, mobile business VoIPs is a whole different ball game. The most important reason is Quality of Service or QoS. All VoIP companies are required to meet QoS protocols which include an evaluation of jitter, latency and delay, ensuring a certain amount of resources are allocated to voice calls.

Don’t forget to factor in bandwidth, though. If you’re using WiFi, your call is only as good as the bandwidth it is using. Working from a crowded coffee shop full of people using the network might slow you down.

It’s also worth remembering that unlike wired-in VoIP on desktop and in the office, your data charges may vary from provider to provider. While the calls themselves may not be charged, the use of the internet might well be. Users will need to be aware of how much mobile data they have to play with and how much will be used, especially with data-heavy tasks such as video calls. Of course, using home WiFi or any other connection can bring those costs down.

Other common concerns you may want to talk to your mobile VoIP provider about include:

  • Your VoIP works seamlessly between desktop and mobile, updating in real time, for example when it comes to reporting or client management.
  • The ability of the mobile VoIP app to work in the background, allowing you to continue other work or check email while you take part in a call.
  • Degradation issues. Can you limit the bandwidth for certain parts of the interaction, for example giving more resources to voice over video quality, or helping to send a file more quickly?
