The Best Auto-Attendant Phone Systems of 2021

There’s no limit to where RingCentral’s auto-attendant phone system can redirect calls. You can establish toll-free and vanity numbers for accepting calls, while they can be forwarded worldwide. If the extension or number is unavailable, the system sends it to the appropriate voicemail.

RingCentral manages and filters the workflow, delegating it to the correct employee or agent. There’s also a dial-by-name automated business directory so clients can choose who to be redirected to. If your company’s administrator is out of the office and system changes need to be made, they can alter settings from the comfort of their mobile device.

Features include:

• Toll-free and vanity numbers
• Extension routing
• Call delegation
• Call flip and parking
• RingOut

You can select one of four subscription plans based on your business requirements, the price increasing with the amount of features.

Ooma has several call management functions you can install alongside your auto-attendant. Some are rather interesting, such as transferring music and extension dialing and monitoring. It can even forward calls when the phone sets aren’t working.

Since it forms part of a more extensive system, you’ll find numerous integrations tied to the service. For instance, there are voicemail transcribing and flexible numbers. Mobile apps have their own set of features, such as simultaneous ringing, SMS messaging from missed calls, and call flip.

Features include:

• Desktop application
• Call routing
• Multi-call options
• Ring groups
• Flexible numbering

Ooma offers two price packages with different features for each. There’s a generous 60-day free trial, so you'll have plenty of time to test your options.

Dialpad has some interesting features in its auto-attendant phone system technology. Instead of listening to voicemails, the platform transcribes the words into text you can read at your leisure. It’s a helpful tool when you’re in a meeting and want to make sure the call wasn’t an emergency.

Of course, the digital receptionist’s primary focus is call forwarding and parking. There’s automatic call distribution to ensure verbal inquiries reach the right team members. It also includes a call summary, presenting the most significant notes and snippets.

• Robust menu system
• Flexible tools
• Online webinar training

Vonage offers three payment plans per line monthly. You can choose to view the demo or test a 14-day free trial.

The auto-attendant phone system has several functions you can maintain. Some of these include call transfers, screens, blocks, recording, parking, handling rules, and logs.

It holds a dial-by-name directory to let clients select specific employees to redirect to in the list. You’ll need to set it up according to a structure in the menu and sub-menus, but it’s an effective method for customers to find the right person if they don’t know the department.
