Professional Phone Messages: The Complete 2026 Guide
Greeting, on-hold, IVR, after-hours: everything you need to know to create professional phone messages that strengthen your brand.
TL;DR: A professional phone message covers four needs — greeting, on-hold, IVR and after-hours. 70% of callers hang up after 60 seconds of silence (CNN). This guide walks through scripts, voice selection (AI or studio), music, technical formats and common mistakes to avoid.
A customer calls your business. Nobody picks up. They hear silence, then a beep, then nothing. They hang up and call your competitor.
This scenario plays out thousands of times every day. According to a CNN survey, 70% of callers who hear silence hang up within 60 seconds. And among those who hang up, 30% never call back (Snap Recordings).
Phone messages are often the very first point of contact between your business and a potential customer. Yet most SMEs still neglect them: the PBX’s default hold music, a greeting recorded on a smartphone, or worse, no message at all.
This guide covers everything you need to create phone messages that actually hold up: the four types of messages, script writing, voice selection, music, technical formats and mistakes to avoid.
What are the four types of phone messages?
Every business needs four distinct messages. The greeting sets the tone. The on-hold message keeps the caller on the line. The IVR routes them to the right person. And the after-hours message prevents losing contacts outside business hours.
The greeting message (pre-answer)
This is the first sound a caller hears, before anyone even picks up. Its job: identify the company, reassure the caller they dialled the right number, and make a professional first impression.
A good greeting message lasts between 8 and 15 seconds. Any longer and the caller gets impatient. Any shorter and they can’t identify the business.
Typical content:
- Company name
- A simple welcome (skip “your call is important to us”)
- Optionally, a useful piece of information (website, business hours)
Example: “Hello, you’ve reached Dupont Ltd. We’re connecting you with a team member now.”
The on-hold message (music and information)
Hold music kicks in when all lines are busy. Without music or a message, the caller hears silence or a line hum. They start wondering whether the call dropped.
The numbers speak for themselves: callers who hear music stay on the line 3 minutes longer than those left in silence (North American Telecom). According to On Hold Messaging Direct, 20% of callers make a purchasing decision while on hold.
A good on-hold message alternates between music and informational messages every 20 to 30 seconds:
- Business hours
- Website address
- New services or promotions
- Reassurance that someone will answer shortly
The interactive voice menu (IVR)
The IVR (Interactive Voice Response) lets callers navigate through numbered or voice-based options. Well designed, it cuts handling time for every call. Poorly designed, it drives customers away.
A good multilingual IVR follows three rules:
- Maximum 4 options per level. Beyond that, callers forget the first ones.
- Maximum 2 levels deep. Three or more levels and it becomes a maze.
- “Speak to someone” always available. 73% of callers want to be able to reach a human (Call Centre Helper).
Example: “For sales, press 1. For technical support, press 2. For accounting, press 3. To speak with a team member, please hold.”
The after-hours message (voicemail / out of office)
This message plays outside business hours. It confirms the company exists, communicates the schedule, and offers an alternative (email, website, callback).
A good after-hours message:
- Confirms the company name
- Gives the business hours
- Offers an alternative contact method (email, online form)
- Invites the caller to leave a voicemail if the system allows it
Example: “You’ve reached Martin & Associates. Our offices are open Monday to Friday, 8:30 AM to 5:30 PM. You can email us at info@martin-associates.be. Talk soon.”
Why do phone messages matter so much?
60% of callers put on hold without music or a message hang up within 40 seconds (Snap Recordings). That figure alone justifies the investment. But the impact goes well beyond the abandonment rate.
First contact = first impression
For many customers, a phone call is still the very first contact with a company. Before they even talk to someone, they judge your professionalism based on the quality of the message they hear.
A clear, well-recorded message with a pleasant voice and fitting music says: “this company is serious and respects my time.” Silence followed by a beep says the opposite.
Retention and commercial opportunity
According to a U.S. West study, an informative on-hold message increases caller retention by 40%. Those minutes on hold aren’t wasted — they can inform callers about your services, remind them of your website or highlight a current offer.
Brand consistency
The tone of your phone message should mirror your website, emails and overall communication. A law firm doesn’t use the same tone as a sports shop. This consistency builds trust.
How to write an effective phone script
An effective phone script takes 15 minutes to write when you follow a method. The fundamental rule: every word must earn its place. Attention spans on the phone are short. Every unnecessary second is a second the caller might hang up.
Recommended structure by message type
| Type | Ideal length | Required elements | Avoid |
|---|---|---|---|
| Greeting | 8-15 sec | Company name, welcome | ”Your call is important” |
| On-hold | 30-45 sec (loop) | Useful info + music | Identical message on repeat |
| IVR | 20-30 sec | Clear options, max 4 | Nested sub-menus |
| After-hours | 15-25 sec | Hours, alternative contact | Funeral tone |
Seven writing principles
- Lead with identity. The company name must appear within the first 5 seconds.
- Write for the ear. Read the script out loud. If a sentence sounds awkward when spoken, rewrite it.
- Keep sentences short. 12 to 18 words maximum per sentence. Beyond that, the caller mentally checks out.
- Ban jargon. “Your dedicated point of contact will process your enquiry” = bad. “A colleague will be right with you” = good.
- Include useful information. Every on-hold message should deliver something: a schedule, a service, a website.
- Skip empty promises. “We are committed to…” has zero value. Giving an estimated wait time — that’s useful.
- Match the tone to your audience. A medical practice uses a calm, reassuring tone. An events agency can afford more energy.

How to choose between AI voice and human voice?
Voice synthesis has taken a giant leap over the past three years. AI-generated voices have become virtually indistinguishable from human voices in a phone context. Each approach has its strengths.
AI voice vs traditional studio comparison
| Criterion | AI Voice (TTS) | Traditional studio |
|---|---|---|
| Production time | A few minutes | 3 to 10 business days |
| Cost | Starting from a few euros | 80 to 300 EUR per message |
| Text changes | Instant, at no extra cost | New studio session |
| Sound quality | Excellent (ElevenLabs, etc.) | Excellent |
| Available languages | 30+ languages, instant switch | Hire a new voice talent |
| Emotion / nuance | Good, constantly improving | Naturally excellent |
| Usage rights | Included in the licence | Varies by contract |
The full AI studio vs traditional studio comparison details when each option is preferable.
When to choose AI voice
- The message changes regularly (promotions, seasonal hours)
- Multiple languages are needed
- The budget is tight
- The timeline is short, for instance when setting up a new phone number
When to choose a studio
- The brand already has an established voice talent (radio spots, TV ads)
- The message is meant to stay unchanged for several years
- A very specific tone is required (storytelling, strong emotion)
In practice, many businesses combine both. A studio-recorded greeting for brand continuity, and AI-generated on-hold messages for easy updates.
What music should you pick for your phone messages?
Background music accompanies the on-hold message and sometimes the pre-answer greeting. The choice isn’t trivial: the wrong music annoys callers, and unlicensed music can lead to hefty fines.
Music rights in brief
Using a commercial song as phone hold music is illegal without a licence. In Belgium, SABAM manages the rights. In France, SACEM. Fines for unauthorised use in a business context range from a few hundred to several thousand euros.
Three legal options:
- Royalty-free music. One-time licence purchase, unlimited use. This is the most common option for SMEs.
- Public domain music. Works whose rights have expired. Heads up: the recording itself may still be protected, even if the composition isn’t.
- Original music. Custom-composed. More expensive, but you get exclusivity.
Platforms like VoiceLab offer a built-in catalogue of royalty-free music, which takes the licensing question off the table entirely.
Choosing the right musical style
The musical style should match the company’s image and the context of the call:
- Medical practice, law firm: acoustic piano, light strings, slow tempo (60-80 BPM)
- Real estate agency, consulting: soft jazz, lounge, sophisticated
- Retail, shops: instrumental pop, upbeat but not aggressive (100-120 BPM)
- Tech, startup: ambient electronic, modern, minimal
- Trades, local business: acoustic, guitar, warm
Volume and mixing
The music volume must be low enough not to drown out the voice, but present enough to fill the silences. Here are the recommended levels:
- Voice: -16 LUFS (main level)
- Music under voice: -26 to -30 LUFS (10 to 14 dB below the voice)
- Music alone (between messages): -20 to -22 LUFS
Transitions between music and voice should be gradual (0.5 to 1 second fade) to avoid abrupt cuts.
What audio formats does your PBX expect?
Every phone system has its own requirements when it comes to audio formats. Sending a stereo MP3 at 320 kbps to a PBX that expects mono WAV at 8 kHz guarantees poor quality or outright rejection.
Standard telephony formats
| Format | Codec | Sampling | Primary use |
|---|---|---|---|
| WAV PCM | Linear PCM | 8 kHz, 16-bit, mono | Universal PBX standard |
| WAV A-law | G.711 A-law | 8 kHz, 8-bit, mono | Europe, Asia, Africa |
| WAV u-law | G.711 u-law | 8 kHz, 8-bit, mono | North America, Japan |
| MP3 | MPEG Layer 3 | 44.1 kHz, variable | Hold music (some PBXs) |
| GSM 6.10 | RPE-LTP | 8 kHz, mono | Asterisk, FreePBX |
G.711: the global telephony standard
The G.711 codec, an ITU-T standard since 1972, is the native format for digital telephony. Two variants:
- A-law: used in Europe and most of the world. Logarithmic compression optimised for low signal levels.
- u-law (mu-law): used in North America and Japan. Slight difference in dynamic range compared to A-law.
Audio bandwidth is limited to 300-3400 Hz (standard telephone band). Everything below 300 Hz or above 3400 Hz gets cut. As a result, a voice recorded with a professional mic at 48 kHz will sound different once converted to 8 kHz for the PBX.
Audio normalisation (LUFS)
LUFS normalisation (Loudness Units relative to Full Scale) ensures consistent volume across messages. Without normalisation, callers experience volume jumps between the greeting and the on-hold message — which sounds unprofessional.
Technical recommendations:
- Target: -16 LUFS for voice, -20 LUFS for the final mix (voice + music)
- True Peak: do not exceed -1 dBTP to avoid distortion after conversion
- Export format: always export to WAV PCM 16-bit first, then convert to the target format (A-law, u-law) to preserve quality
Common PBX compatibility
| PBX / Platform | Preferred format | Notes |
|---|---|---|
| Asterisk / FreePBX | WAV GSM 6.10 or u-law, 8 kHz mono | Conversion via sox recommended |
| 3CX | WAV PCM 16-bit, 8 kHz mono | Or MP3 for hold music |
| Vodia | WAV PCM or A-law, 8 kHz mono | Direct upload via the interface |
| Teams Phone | MP3 or WAV, 16 kHz recommended | Microsoft accepts wider formats |
| Cisco UCM | WAV u-law, 8 kHz mono | Very strict format |
| Yealink / Grandstream | WAV PCM, 8 kHz, 16-bit, mono | Via provisioning or web interface |
What are the most common mistakes?
Even with a solid script and a great voice, certain technical or strategic mistakes can ruin the impact of your messages. Here are the most common ones, observed across hundreds of SMEs.
1. No message at all
The worst-case scenario. The caller hears an endless ringtone, then nothing. They hang up, call a competitor, and never come back. Yet this is the default state of most phone systems out of the box.
2. The manufacturer’s default message
“Please hold. Your call will be answered in the order it was received.” This generic, robotic PBX voice tells your customer that nobody bothered to configure the phone. Not exactly the signal of professionalism you’re going for.
3. A message that’s too long
A 45-second greeting before the caller can actually speak to someone is counterproductive. The caller has a specific question and wants a quick answer. Every extra second increases frustration.
4. The repetitive loop
Hearing the same 30-second message repeated identically every 30 seconds for 5 minutes is unbearable. Plan at least 3 different messages in rotation.
5. Music too loud or too quiet
Music drowning out the voice = inaudible. Music barely perceptible = the caller thinks the line dropped. Correct mixing is a precise balance (see the LUFS section above).
6. Outdated information
“We’re closed for the Christmas holidays” in March. “Visit our new website” launched three years ago. Bottom line: review your messages at least twice a year — before summer and before the holidays.
7. Ignoring multilingual needs
In Belgium, a message only in French excludes Dutch-speaking and English-speaking customers. In Switzerland, a message without German or Italian is a commercial mistake. Multilingualism is not a luxury.
8. Wrong audio format
A stereo file at 44 kHz sent to a PBX that expects mono 8 kHz produces metallic, distorted or truncated sound. Converting to the right format is a technical step you must not skip.
Checklist: create your messages in 8 steps
- List your needs: greeting, on-hold, IVR, after-hours, seasonal messages
- Write the scripts: one script per message, following recommended durations
- Choose the voice: AI or studio, language(s), tone matched to your industry
- Select the music: royalty-free, style consistent with your brand
- Produce the audio files: recording or TTS generation + voice/music mixing
- Normalise the volume: -16 LUFS voice, -20 LUFS mix, True Peak below -1 dBTP
- Export in the right format: check your PBX specs (A-law, u-law, PCM)
- Test on the live system: call your own number, check quality, transitions, volume levels
FAQ
What is the ideal length for a phone greeting message?
Between 8 and 15 seconds. The greeting must identify the business and reassure the caller without making them wait. Beyond 20 seconds, the abandonment rate increases significantly, especially on mobile where people are less patient.
Do I need a licence to use hold music?
Yes, unless you use royalty-free music or public domain music. In Belgium, SABAM controls music broadcasting rights in a business context. Fines for unauthorised use are real. The simplest solution: use a royalty-free music catalogue designed for telephony.
What’s the difference between A-law and u-law?
Both are variants of the G.711 codec for digital telephony. A-law is the standard in Europe, Asia and Africa. U-law (mu-law) is used in North America and Japan. If your business is in Europe, your PBX most likely uses A-law. When in doubt, WAV PCM 8 kHz mono works on virtually every system.
How much does it cost to create professional phone messages?
In a traditional studio, expect between 80 and 300 EUR per message (voice + mixing + music). With a platform like VoiceLab, the cost drops to a few euros per message, with the ability to change the text instantly. The total budget to equip an SME (4 basic messages) ranges from 20 EUR to over 1,000 EUR depending on the approach chosen.
How often should you update your phone messages?
At least twice a year: before the summer holidays and before the end-of-year holidays. Ideally, whenever your hours, services or promotions change. Businesses using AI voice update their messages much more frequently, since changes cost almost nothing in time or money.
Does an IVR drive customers away?
A poorly designed IVR, yes. Menus with 8 options, 3 levels deep and no way to reach a human will drive everyone away. But a well-thought-out IVR with 3 or 4 options maximum, a single level and direct access to an agent reduces handling times and improves satisfaction. The key: test your IVR yourself by putting yourself in the caller’s shoes.
Key takeaways
Phone messages are not an administrative detail. They are real communication tools that influence how your business is perceived, how well you retain callers, and ultimately, your revenue.
Four messages are enough to cover most needs: greeting, on-hold, IVR and after-hours. Writing follows simple rules (short, clear, useful), the voice can be AI-generated or studio-recorded, and the technical format must match what your PBX expects.
The most expensive thing isn’t creating these messages. It’s not having them.
