“Good but not great”

May 31, 2021 11:40 AM

Corvum's team is Canadian and very responsive, which I like. However, the integration with Clio, which is otherwise a top selling point, does nothing for me. Corvum doesn't integrate with any of my apps. You can text off the browser app, which has low mobile functionality. There is no corresponding android app (although there is an apple app) that allows text messaging, making this feature more of a hindrance than a help unless you use the browser based app frequently. Prices are good and the team is great; however, it is costly to add other users or phone numbers and there are no decent workarounds. It includes voip fax if you need it but the fax number doesn't seem to be portable.

Additional Details about Corvum

Setting Up Auto-Attendant

Corvum allows you to create business rules for phone calls that come into your office (i.e. after 3pm, all calls route to a particular member of your team). These are often complex to assemble and the view under-the-hood can, at times, be daunting. The Corvum team is happy to help you create, edit and adjust these rules as needed.


Visual Voicemail. Although Visual Voicemail is very common on our smartphones and some other applications, it is important to note that Corvum has it. This feature allows you to download MP3s of your messages and save them to your file if necessary. Additionally, it allows you to access your messages using a visual dashboard instead of calling into your Voicemail Box.

Voicemail to Text. As speech-to-text recognition has gotten better, the value of automatically transcribing your voice messages to text has increased. This is especially valuable for attorneys who find themselves in Court or other venues where they can check their email, but wouldn’t be able to call-in to their voicemail box.

Business Text Messaging

Corvum’s Business Text Messaging, their newest feature as of this review, may not be as feature-filled as other products like ZipWhip, but it likely has all the functionality a small to medium-sized practice needs. Although the most useful part of business text messaging services is not needing to use personal cell phones for client communications, most attorneys will find the ability to create searchable, downloadable text strings to be useful. Those attorneys who use Clio will even be able to sync these strings to their client communications.

Sync with Clio

As we have said at Lawyerist before, not all synchronization claims are the same. Ideally, when connecting information to and from an LPMS, you want to look for push-pull synchronization, which Corvum has. This means that not only does the Corvum system retrieve information out of Clio, it will also send information directly to Clio for filing. For example, contacts from Clio can be accessed in the Corvum system, and new contacts created from Corvum will automatically show-up in your Clio system.

Software Phone

In order to make and receive phone calls with Corvum, you’ll need to download a software phone from Bria (which comes with your Corvum service). The benefit of these “soft” phones, and possibly the main benefit of VoIP altogether, is that you take your phone with you wherever your computer is (or wherever your smartphone is). You can download this app for desktop computers, mobile devices, or even desk phones that are set-up for VoIP connectivity.
