What voicemail actually does
Voicemail plays a greeting, records what the caller says and plays it back to you. It may be supplied by the operator with the line or the phone system: in France, Free Pro’s Coms Pro, for example, includes voicemail, and Orange pro lists it among the features of virtual phone systems on its business telephony page.
Its limitation is structural: it cannot say anything beyond the recorded message. A caller who leaves a message has to wait for your callback to get an answer.
What an AI voice agent does on top
Alyas picks up, states that it is an AI and that the call is recorded, then listens to the request. If it is a question covered by the information you have provided (opening hours, services, service area, documents to bring), it answers directly.
Otherwise, it takes the caller’s name, number and reason for calling, offers an appointment if your calendar is connected, or transfers to the number you have set. You receive a written transcript and summary, instead of audio messages to listen to one by one.
When a simple voicemail is enough
If you receive few calls, if most come from customers who know you and are happy to be called back, or if your calls never require an immediate answer, a well-recorded voicemail does the job, at no extra cost if voicemail is included in your package.
A good professional greeting takes just a few sentences: the business name, the reason you are unavailable, the times you can be reached, an invitation to leave a name, number and reason for calling, and possibly another way to get in touch, such as the website or an email address.
When a voice agent becomes useful
The agent comes into its own when callers often ask the same questions, when a missed call means a customer lost to a competitor, or when listening to and sorting messages takes up real time every day. It also covers evenings and weekends, 24/7.
Our Call answering page describes these uses; the 10-day free trial, no card required, lets you compare it, on your own calls, with what your voicemail was delivering.
Our verdict
A business with a low call volume and customers used to being called back can stick with a well-crafted voicemail. As soon as questions keep repeating or every missed call is a potential sale, a voice agent like Alyas provides an immediate answer that voicemail cannot give.
Frequently asked questions
What should a professional voicemail greeting say?
The business name, the reason you are unavailable, the times you can be reached, a request to leave a name, number and reason for calling, and if useful another way to contact you. Keep it short: a few sentences are enough.
Can an AI voice agent take messages like voicemail?
Yes, and in a more usable form: it collects the contact details and the reason for the call, then sends you a transcript and a summary rather than an audio file to listen to.
Does the caller know they are talking to an AI?
With Alyas, yes: at the start of the call, the agent announces that it is an artificial intelligence and that the conversation is recorded.
