Vast Conference Pricing

Conference Calling by Vast Conference offers two types of pricing plans for its reservationless service: monthly and pay-as-you-go. With the monthly plans, you pay a flat fee every month and can host as many meetings as you like. There are four unlimited monthly plans:


  • Price: $14.99 per user, per month
  • Participants: 10
  • Cloud recording: 1GB

  • Cloud recording: Unlimited


  • Price: Customized for each business
  • Participants: 500
  • Cloud recording: Unlimited

Businesses that opt to pay annually instead of monthly save 20%. The service offers a 14-day free trial. 

Conference Calling also offers a pay-as-you-go plan. This option, which supports up to 500 callers, is 3.5 cents per caller, per minute. For example, if you have a 30-minute meeting with 10 participants, the call would cost $10.50. 

There are several add-on services you can purchase with the reservationless plan, including transcription services, custom greetings, CDs of recordings and additional host accounts.

The operator-moderated service is only available in a pay-as-you-go offering. This service costs 16 cents per caller, per minute for a standard event and 19 cents per caller, per minute for a premium event.

There are several features that cost extra with the operated-assisted service, including custom scripts, subconference rooms, pre-recording services, recording services, digital replay services, call transcriptions, participant list, conference polling reports and web conferencing. Custom pricing for these services is available by contacting Vast Conference directly. 

There are no contracts with Vast Conference, and you can cancel or change plans at any time.

Vast Conference Calling Services 

A benefit of Conference Calling by Vast Conference is that it offers both types of conference calling services: instant calls, also known as reservationless, and operated-assisted conference calls. 

Reservationless: Reservationless calls leave the scheduling up to you. You can schedule calls for any time or hold them instantly when an impromptu meeting is necessary.  You send participants the conference line and access code, along with the time of the meeting.

When the meeting begins, participants dial in and enter the provided codes. Depending on the plan you choose, the reservationless option lets you host meetings with up to 500 participants.

You can also turn a conference call into an online meeting. The conferencing service allows for web conferencing and screen sharing.

Operator-moderated: Operated-moderated (or operator-assisted) calls are typically used by larger organizations that host large, formal conference calls, such as public companies that hold annual or quarterly investor calls. With this service, Conference Calling operators assist you before, during and after your conference call. 

Before your call, an operator, which Conference Calling refers to as an event specialist, is assigned to you. They work with you to develop the greeting and introductions and set up the call's flow and itinerary. On the day of the call, the event specialist meets with the call's host and any other speakers to review the final details.

During the call, the event specialist can greet participants and collect their contact information. Once the call starts, the specialist remains on the line to introduce each speaker and manage any question and answer session.

Once the call is completed, the event specialist provides you a participant list, a recording of the call and a transcription, if needed.

Operated-moderated calls support up to 6,000 attendees.


Vast Conference Pros and Cons

It addition to the flexibility of multiple cost structures and types of conference calls, the wide range of call features is a big bonus with this service. Customizable greetings and call recordings are among some of the standout features.

You can create your own greeting for callers, giving them a personalized welcome. You can record your own greeting or provide Vast Conference a script and have one of their voice actors create the greeting for you.

All calls can be recorded at no additional charge. With the push of a button on their phone, the host can start recording, and participants will hear a message stating that the call is being recorded. Recording can also be started and stopped from the online portal. There is no limit to the number of recordings you can make. Each recording can be downloaded as an MP3 file, and a link can be emailed to anyone who needs to access the recording. You can listen online or by phone.

Conference hosts also have total control over running the call from the online portal. The web tools allow the host to see everyone who is on the call, mute callers when necessary, and conduct Q&A sessions. There’s also a feature that allows the host to dial out to any U.S. telephone number, even mid-meeting, to add someone else to the call.

In addition to controlling calls via the web manager, the host can control the call straight from their phone's dial pad. For example, 1* mutes all callers, 6* can request that each participant state their name so you know who is on the call, and 9* toggles the entry notice (which alerts you when a new participant has joined the call) on and off. Participants can use their dial pad to control their portion of the call, such as to mute themselves and ask permission to speak. 

For those looking to take their conference to the next level, video conferencing and screen sharing are also available. The HD video conferencing allows participants to meet face-to-face.

If you need to share visuals with your audience during your meetings, Conference Calling offers HD screen-sharing services. With this, you can host web conferences that allow you to share your screen, instant-message participants and send files to the group.

There are a number of other factors that make Conference Calling by Vast Conference an impressive service. For businesses that hold meetings with international participants, Conference Calling offers local numbers in more than 80 countries worldwide. There are also international toll-free options.

Conference Calling also integrates with Microsoft Outlook by adding buttons to your Outlook Home toolbar from which you can instantly create conference call invitations with an email template or calendar appointment. The pertinent information is automatically populated in your invitation.

And finally, call continuation allows the meeting to continue without the host on the call.

While we were extremely impressed with the service, there was one minor negative. Currently, Vast Conference does not offer a mobile app for either iOS or Android devices. Other services we looked into had their own mobile app that allowed users to host meetings from their smartphones.

The good news, however, is that representatives we spoke with said a mobile app is currently in development and should be released in the second half of 2019.

Even without the app though, Vast Conference does make it easy to participate in conference calls from your mobile device. Instead of having to dial in directly to a call, participants can join a conference with one push of a button from their smartphone. 

Vast Conference Customer Support

The customer support from Vast Conference was impressive. To test the level of service offered, we contacted the company several times by phone posing as a small business owner interested in conference calling services.

Each time we contacted the company, we had very helpful and pleasant exchanges. Our calls were always answered immediately, and our questions were always thoroughly answered. By the end of each call we had a clear understanding of how the service worked, what it had to offer and how much it would cost.

This service offers telephone, email and live-chat help and support options. The Vast Conference website is also filled with helpful training materials.

The company has an A- rating with the Better Business Bureau, and as of June 2019, only one complaint had been filed against Vast Conference in the past three years.
