Business Phone System for Law Firms

As a law firm, your telephone communication system has a direct impact on your clients’ legal outcomes. If you were stuck in court and missed an important voicemail, it could affect years of a client's life. Additionally, a good communication system is critical to your business’s profitability and the ease with which you can do your job.

Seamless Mobile Integration

Ooma’s enterprise-level phone system is a comprehensive solution with advanced integration capabilities. For lawyers who may not always be at their desks, the ability to have access to their office phones while they are away is golden. Even though we all have cell phones in our pockets, shifting between two phone numbers and two voicemail boxes is complicated for both staff and clients.

The Ooma Office mobile app lets you make and receive cell phone calls as though you were in the office. Your phone number will always show your office line, keeping a consistent and professional appearance. This gives you the flexibility to return calls when and where you want to.

And you’ll never miss a voicemail because you can check your voicemail box through the app. Ooma even offers voicemail-to-email forwarding so you can easily access your messages and log the audio with your case files.

Ooma Makes Your Law Firm Look Good

Even if your law firm is still small, having a professional image is critical. Ooma Office includes big business features that will make all of your client communications look and sound top of the line.

Features include a virtual receptionist to greet your clients and direct calls. The phone system offers extension dialing and call transferring. You can customize ring groups that route calls to multiple extensions so calls are always answered. There is music on hold for when people wait, and there is a conference bridge for meetings. There is even a toll-free telephone number included with Ooma Office.

These features would cost a great deal if you purchased them individually or through a traditional phone provider, but they’re all included with your Ooma Office account.

Makes Client Billing Easier

Running a successful law practice involves accurately and efficiently billing clients, and Ooma’s call logs can be exported so that phone time can easily be added to invoices. Having digital call logs means that you can easily sort the billable hours spent on the phone by the name and number of the client, what staff member took the call, what the date the call occurred on, and what the duration of the call was.

Similarly, Ooma’s virtual faxing process that lets you send and receive faxes without needing a physical fax machine also offers a log of incoming and outgoing faxes. So if you’re billing your clients for faxes, it’s easy to simply export the fax log from Ooma Office and add the information to your invoices.
