VoIP Phone System For Law Firms & Offices
Law firms can take advantage of a VoIP service in unique ways to help make their business run more smoothly. It’s particularly important for a law firm to present a professional and polished impression, regardless of its size.

A VoIP system helps even very small law firms answer calls professionally and deal with out of hours calls in a supportive and streamlined manner.

How Does VoIP Help Law Firms Cut Costs?

Whatever the size of your law firm, you’ll be happy to reduce your communications’ costs with a VoIP system. Most VoIP providers are able to offer much cheaper calls per minute locally, nationally, and internationally, thanks to the lower cost of internet-based calls when compared to traditional international calls.

The video-conferencing and audio conference call features also help law firms to save on transport costs and conference facilities since there's no longer a need to bring everyone together physically or shell out for meeting space. Finally, the ability to integrate existing business tools with your VoIP service means that there’s no need to buy new tools or get used to using a different system. You can start saving money on communications straight away with a VoIP solution for your law practice.

Why do law firms need to have an office phone system? 

Law firms need a reliable and affordable office phone system to enable internal and external communication. The best phone system for small law office buildings is one powered by a voice over internet protocol (VoIP) because it offers mobility, convenience, consistency, flexibility, and integration with other tools and features to make communication more effective.

VoIP for lawyers will provide the same phone number for multiple desktop and mobile devices, maintaining consistency throughout the firm. Your law practice will appear professional since the calls are to an office number rather than a personal one. Moreover, there won’t be any missed client calls because authorized team members can pick up the call through their own VoIP-connected devices.

What are some of the most important VoIP features for lawyers?

Audio call management

Lawyers review communications with their clients to ensure they’ve understood all the case details, which is crucial for representing them comprehensively in court or arbitration. VoIP for law firms will offer call recording features, enabling you to refer to the audio when needed.

There’s also a call forwarding option to ensure you never miss a client’s or witness’s call when you’re out of the office. The Call Flip feature makes it possible to switch calls from your desktop to your mobile phone if you’re leaving the office in a hurry. For example, if you have to rush out to go to court suddenly.

If you’d like to read and send messages rather than listen to voicemails, VoIP offers voicemail-to-text transcription, making it easy to read the transcript or send the message as an email quickly.

Video calling and conferencing

With remote work becoming commonplace, being able to speak to clients or colleagues via video is vital for enhancing communication. It’s said that we communicate more nonverbally, and so it can be better to conduct calls via video on some occasions, for example, to check how your client is holding up. Law firm VoIP provides video calling and conferencing tools for team members to collaborate on cases or to talk to new and long-term clients.

Mobile VoIP app

A mobile VoIP (mVoIP) app provides every lawyer in the firm access to its registered VoIP number, subscription plan, and features. mVoIP enables you to continue working and discussing cases with experts or your colleagues and serve clients remotely.

Software Integrations

VoIP provides software integrations, such as with customer relationship management (CRM) systems, which ensure secure access to client files even when you’re out of the office. Lawyers in the firm can also update the system if they get a new client, guaranteeing easy onboarding.

Professional auto attendants

The virtual receptionist can pick up calls and route them to the correct department, thereby reducing waiting times for clients on the line.

How to choose a VoIP provider for law offices?

Here are a few factors to consider when choosing the best phone system for small law office buildings:

  • Research online - Conduct research on top VoIP providers, read reviews, and check their industry experience, record, and awards. Confirm their uptime statistics to be sure you’ll get consistent and reliable VoIP connections.

  • Compare prices and plans - Figure out what your law firm needs and check the subscription plans that can help you reach your goals.

  • Get references -  Speak to friends and other lawyers in your area to learn about their experiences with different VoIP providers and see what works for you.

  • Use free trial offers - Sign up for a VoIP service for the duration of their free trial subscription. Experiment with their features to determine if they can address your firm’s communication requirements.

  • Talk to their customer care - Reaching out to customer support will help you get a feel for the VoIP company’s professionalism. Poor customer service can hurt your law firm since you won’t be able to get the timely assistance you want to serve your clients well.

  • Scalability - Your VoIP phone service should be able to grow as your law firm and team grows.

VoIP Helps Law Firms Deliver Exceptional Service to Clients

What makes a law firm stand out is the level of customer service that it delivers. This is true for every business, but lawyers in particular need to be able to listen to their clients and make them feel confident about their services. 

The call recording, call tracking, and logging features offered by the best VoIP providers help legal personnel keep on top of every detail. Effective VoIP systems also improve customer service by saving you time. 

Fast and efficient call transfers mean that clients don’t need to wait while the right person is located to take the call, and there’s also less chance of accidentally dropping an important call. By enabling your legal secretary to filter calls, a VoIP system allows you to focus on the clients that need your attention the most and divert less-pressing matters to be dealt with by other members of staff.

VoIP providers help lawyers respond accurately and confidently to every caller, even if they’re out of the office because they'll have all the information about the client at their fingertips through the cloud. Your clients' confidentiality will be kept from compromise as long as your VoIP system is one of the many that includes secure, encrypted communications.
