Additional Details about Corvum

Setting Up Auto-Attendant

Corvum allows a firm to create business rules for incoming office phone calls (e.g., after 3pm, all calls route to a particular team member). These are often complex to assemble, and the view under the hood can sometimes be daunting. The Corvum team will happily help customers create and adjust rules as needed. 


Visual Voicemail

Although visual voicemail is common on smartphones and some other applications, it is important to note that Corvum provides it. Voicemails can be downloaded as MP3 files and stored in the electronic case file if necessary. Additionally, it allows users to access messages using a visual dashboard instead of dialing into a voicemail box.

Voicemail to Text

As speech-to-text recognition improves, the value of automatically transcribing voice messages to text increases. This is especially valuable for attorneys in court or other venues where they can check their email but wouldn’t be able to call into a voicemail box.

Business Text Messaging

Corvum Texting, 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 valuable part of business text messaging services is avoiding personal cell phone usage for client communications, most attorneys will find the ability to create searchable, downloadable text strings useful. Attorneys with Clio can even sync these strings to their client communications. 

Sync with Clio

As we have said at Lawyerist, not all synchronization claims are identical. Ideally, when syncing information to and from an LPMS, look for push-pull synchronization, which Corvum has. Push-pull sync means that the Corvum system retrieves information from Clio and also sends information directly to Clio for filing. For example, contacts from Clio can be accessed in the Corvum system, and new contacts created in Corvum automatically appear in the firm’s Clio system. 

Software Phone

Making and receiving phone calls with Corvum requires a software phone application from Bria. A Corvum subscription includes this program. The benefit of these “soft” phones, and possibly the main benefit of VoIP overall, is that a user’s phone is available wherever that user’s computer or smartphone is. Bria makes versions of its apps for desktop computers, mobile devices, and even desk phones set up for VoIP connectivity. 

Who Corvum is for

Corvum would be good for any small to medium-sized law firm wanting the functionality of VoIP phone services. It is particularly good for those needing business texting and remote workers requiring access to an “office” phone.

    I’ve been using Corvum for about seven months, and I’ve been disappointed.

    I admit, this is my first time using a VOIP, so it is possible that this one is adequate compared to others.

    Here are my problems:

    1) Voice quality is often poor. I frequently start my call with Bria (Corvum’s App for phone calls), then have to hang up, and call my client back using Google Voice.

    2) The apps are not smooth or user friendly. To use the SMS, you use the Corvum app, which is very limited in function. To use the phone, you use the Bria app, which is not at all intuitive. In fact, I swear they told me it had visual voicemail when I signed up, but I see no such thing in the app.

    3) Settings. Several of the settings for Bria must be selected following specific instructions in the Bria literature. These settings are not intuitive.

    4) Functions. I attempted to have my calls forwarded, but the delay feature has numbers without description. When I referred to the literature, there is no description. I set the “delay” number at 4, thinking it represented 4 rings. Guess not, since I was unable to answer a call for the month until I figured out how to reset it. Maybe it’s 4 seconds? But from whose vantage? From mine, the phone rings once, I answer, and the caller is gone, presumably being forwarded. Another issue is that the app doesn’t remain logged-in on my phone. So, I have to make sure it is signed in daily, otherwise, I will try to make a call and be stymied.

    Positives: Call recording feature is great.

    I would be grateful to hear of options that are better executed than Corvum.

    Good but not great

    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.
