RingCentral’s Service Summary

RingCentral is considered one of the world’s largest VoIP communications services.  Having such a large customer base speaks for itself as far as quality, cost, and competitiveness goes.  RingCentral’s additional services complement the MVP product very well, delivering a whole ecosystem of communication services that cover the needs of most enterprises of almost any size. 

Vonage

Vonage comes from a somewhat different background and legacy compared to RingCentral.  Founded just a year earlier in 1998, it started as a provider of residential VoIP telecom services, one of the first commercial VoIP providers in the USA.  Over the years, and through a series of acquisitions, the company has expanded its presence into business-to-business communication services, delivering unified communications (UC), contact center applications, and communication APIs for integration with third-party applications.

Vonage’s Main Offerings

Vonage provides their Unified Communications service, a cloud-based telephony service delivered to your desktop, laptop, mobile device, or IP desk phone.  It delivers voice, messaging and video and users enjoy over 50 advanced UC features, including productivity and collaboration tools.  It incorporates video conferencing into all its telephony services.

Vonage’s Additional features

In addition to this fundamental offering of UC services, Vonage delivers a multitude of other complementary and stand-alone services and functionalities.  These include:

• Contact centers – These are omnichannel contact center services that incorporate speech analytics, workforce management, conversational AI, as well as integrations with some of the most popular CRM and customer databases.
• Communications APIs – Vonage focuses greatly on the successful integration of its business communication services with other applications via its Application Programming Interfaces or APIs. In this way, advanced customization and deep integration can be achieved vastly enhancing productivity and efficiency.
• Conversational Commerce – This is a feature that can create AI-powered omnichannel experiences that boost sales and increase customer satisfaction

Vonage’s Service Summary

Vonage comes from a voice-only background but has successfully moved into the related and neighboring areas of video communications.  Having said that, Vonage has a very advanced set of products that are geared towards sales, customer support, customer management, and the use of AI to enhance the customer experience.  This in combination with its highly integratable Communications APIs makes it ideal for specialized customer service requirements.

User Experience

RingCentral: Users praise the fast setup, intuitive apps, and smooth onboarding. It’s often chosen by IT teams for its scalability and integrations. Some users note occasional customer support challenges.

Vonage: Known for out-of-the-box reliability and feature-rich customization. Businesses like its CRM-first approach but sometimes find it less intuitive than RingCentral for video collaboration.

Feature set

Both companies deliver a similar set of advanced telephony features such as voice teleconferencing, advanced voicemail features, advanced call handling, music on hold, call history, and call logging features.  Both companies incorporate video calling with their offerings as well.  The truth is the plans of both companies are so phenomenally similar that it has been difficult to find some differences.  Some comments concerning this comparison are found below:

• Both support CRM integrations with many of the most popular business applications and software including Hubspot, Office 365, Salesforce, Sugar CRM, Zendesk, and Zoho
• Vonage delivers service to customers in over 40 countries and can provide local Direct Inward Dial (DID) numbers from over 96 countries

• RingCentral delivers a standalone videoconferencing option called RingCentral Video, something for which Vonage has no counterpart product

The following table contrasts some of the key differences in features

Customer support

Vonage delivers 24/7 customer support via email, chat, and online case/ticket creation.  Via telephone, they are available from 8 AM to midnight on weekdays, and 9 AM to 9 PM on weekends, but emergency on-call after-hours support is also available.  In addition, the support section of the Vonage website is well put together and helps users find information in articles and tech manuals that can be very helpful.  This includes tutorials, videos, and training to get the most of your Vonage service.

Furthermore, there is an active online community where users exchange tips and ideas with other customers which can be very helpful.

RingCentral delivers unlimited 24/7 customer support via telephone and online chat for all plans except the entry-level Essentials plan, where you must use the RingCentral Support home page.  There have been some isolated reports from users concerning problems where it was difficult to reach a live agent on the phone, and when they did, they were not as knowledgeable as one would expect.

This support home page is very comprehensive, and you can quickly get to the topic you’re looking for relatively easily.  Through this support page, and with your credentials, you can open and submit support cases, but you are also able to access the knowledge base that includes articles, manuals, as well as training materials, and webinars. 

RingCentral also has an active online community that users will definitely find useful.

Pricing and plans comparison

RingCentral

RingCentral’s pricing for its MVP offering comes in four tiers.  Cost savings can be achieved by choosing annual billing as well as by increasing the number of subscriptions you wish to purchase.  For a single line, the annually billed monthly cost for each of the three tiers is as seen below:

With annual billing enabled, for 100 or more users, these prices go as low as $22.99 per month for the Standard plan, $32.99 per month for the Premium plan, and $43.99 per month for the Ultimate plan.

Vonage

Vonage’s pricing for its UC offering comes in three tiers.  However, cost savings can be achieved only with an increase in the number of lines included in the purchase.  There doesn’t seem to be any annual billing available for cost savings.  For a single line, the monthly cost for each of the three tiers is as seen below:

For up to 99 users, these prices go as low as $14.99 for the Mobile plan, $24.99 for the Premium plan, and $34.99 for the Advanced plan.  For a larger number of lines, you are asked to contact sales.  This seems to suggest that lower prices are available for bulk subscriptions.

The truth is that both RingCentral and Vonage are among the most expensive VoIP providers out there, but this is no surprise.  Their value for money is still quite high since they usually outperform most other providers.  Having said that, you can see from the following table that, like their feature sets, their prices are also comparable.  All prices shown are for annual billing where it exists.
