Phone prospecting remains sales reps’ least favorite exercise, and one of the most effective when done well. The phone allows what no email can: a conversation, with its questions, objections and subtle signals.

Here are ten tips for effective phone prospecting in B2B, preceded by an essential point: since August 11, 2026, the legal framework has changed profoundly for calls to consumers.

The legal framework, to know before picking up the phone

The French law of June 30, 2025 moved telemarketing to consumers to a prior-consent regime, which came into force on August 11, 2026. A consumer can no longer be called for prospecting purposes unless they have given their prior consent, with limited exceptions such as performing an existing contract. Bloctel, the former opt-out list, no longer serves a purpose.

Even with consent, calls to consumers are regulated: Monday to Friday excluding public holidays, from 10 a.m. to 1 p.m. and from 2 p.m. to 8 p.m., and within a limit of four calls per month. Administrative penalties can reach €375,000 for a company.

This regime targets consumers, not professionals. In B2B, phone prospecting remains possible when the offer relates to the role of the person called. It falls under the GDPR: you must inform the person of how their contact details are used and allow them to object easily. An up-to-date exclusion list in the CRM settles the issue.

The tips below therefore apply to business-to-business prospecting.

1. Prepare an outline, not a script

The idea is not to write a text to recite, which can be heard immediately, but to prepare an outline you can adapt to each conversation:

• a one-sentence introduction of your company;
• the specific reason for your call, linked to the person’s situation;
• three or four open questions;
• answers to the most common objections;
• a proposed next step.

2. Set a clear objective

Before picking up the phone, know what you are looking for: a meeting, a qualification, identifying the right contact. Block a calling slot in your calendar and prepare the list in advance, from a filtered view in your CRM. One prepared session is worth three improvised ones.

3. Capture attention in a few seconds

The person decides very quickly whether to listen to you. The best way to hold their attention is to show that you know their situation: news about their company, an issue in their sector, a genuine connection. Keep their record open during the call, with the history of previous exchanges.

4. Get past the switchboard honestly

The switchboard is not an obstacle to get around; it is often the person who knows who decides. Introduce yourself clearly, say why you are calling and ask for advice. Tricks to get through work poorly and leave a bad first impression, which sometimes reaches the person you are trying to reach.

5. Smile, literally

A smile can be heard on the phone: it changes your voice and rhythm. Speak calmly, without rushing, in a friendly and confident tone. Calling standing up, with the outline in front of you, often helps find that tone.

6. Ask questions rather than argue

The most common mistake is to reel off all your arguments in one go, without letting the other person speak. A prospecting call is a conversation: ask open questions about the person’s situation, priorities and difficulties. They should talk more than you.

7. Listen and take notes

What the prospect says is worth more than what you could have said. Take notes during the call, then immediately record the essentials in their record: need mentioned, timeline, contacts named, objection raised. This memory is what will make the next call relevant, even if a colleague makes it.

8. Handle objections

Identify the nature of the objection before responding: lack of time, no need, solution already in place, wrong contact. Rephrase to check you have understood, then answer the real question. The method is developed in our article on handling objections.

9. Never criticize the competition

Disparaging a competitor comes across as a lack of arguments for your own offer, and often puts the person in an awkward position if they are a customer of that competitor. Talk about what you do well, not about what others supposedly do badly.

10. End with a next step

End every call with a concrete follow-up: a summary email, a meeting, a callback on a specific date. Record it immediately in the CRM as a dated task. A call without a planned follow-up is a call you will have to make again.

Going the distance

Rejections are part of the exercise, including the most abrupt ones. They say nothing about your worth and almost nothing about your method, unless they keep recurring for the same reason. This is where tracking in the CRM becomes useful: it turns a feeling of discouragement into usable data on the targets, hooks and times that work.

The phone is only one channel among others. It reaches its full potential combined with email and LinkedIn, in an overall approach described in our article on B2B prospecting.

Your questions about phone prospecting

Can you still call consumers?

Only if they have given prior consent, or as part of an existing contract. Consent must be explicit and provable, and the legal time slots apply even in this case.

Do you need to check an opt-out list in B2B?

There is no national list for professionals. Keep your own exclusion list and immediately honor any request not to be called again.

When is the best time to call a professional?

There is no universal rule. Test several time slots and measure: your CRM will tell you which ones lead to conversations.

How many follow-ups before giving up?

Three or four spaced-out attempts, varying the channels. Beyond that, silence is an answer, to be recorded as such in the record.

Should you leave a voicemail?

Yes, short and precise, with the reason for the call. A clear message prepares the next call, even if it is never listened to all the way through.
