Microsoft has started certifying voice agents for Teams Phone – and in the same document drew a line around which setups it will support. For any business running its telephony in Teams, that is a clause in the contract before it is a new feature.

Telefónica has built generative AI into the telephony service itself – transcription, summarisation and virtual agents over ordinary fixed-line and mobile voice. The selling point is that the customer never has to change platform. That is also where the ceiling sits.

Twilio's quarterly results show self-service voice growing more than 50 percent – and costs becoming harder to forecast at the same time. That is one piece of news seen from two sides, and the explanation is the unit you buy in.

Most voice agent pilots are set up so that they cannot fail. Which means they cannot settle anything either. Here are the eight steps that turn two weeks into a decision.

Norway's telecom regulator has ruled that call centres may not use 8-digit mobile numbers as their caller ID. If your voice agent makes outbound calls there, the number is a compliance question before it is a marketing choice.

An absence reported at 05:40 has to be covered before the shift starts at 07:00. Few industries work to a deadline that short or that expensive – and almost all of it is spent on the phone.

Norway once changed how an entire country pronounces numbers, because the telephone authority had measured that people were writing phone numbers down wrong. The problem did not go away. It moved to the machine at the other end.

“Our customers want to talk to a person” is the most common objection to voice agents. It deserves to be taken seriously — but it measures something other than what it thinks.

Google can call a business on a customer's behalf. The most interesting sentence in the documentation is about when it doesn't.

Almost every voice agent can transfer to a person. Far fewer teams have decided what triggers it, what the person is told, and what happens when nobody picks up.

Last week's attack on Wall Street's largest hedge funds did not come through the payment flow. It came through the service desk, in a voice the employees recognised.

Sentiment analysis, tone-of-voice detection and frustration alerts ship with most modern telephony platforms. That kind of feature is classified as high-risk under the EU AI Act, but the obligations were pushed back to 2 December 2027 – and pointed at your own staff it has been prohibited since February 2025.

A voice agent that handles 68 percent of calls without transferring looks like a success. The number says nothing about how many of those calls were actually resolved — and even less about what the business did with the capacity it freed up.

Since 2 August 2026, AI systems that interact directly with people must disclose that they are AI. For anyone running a voice agent on the phone, that is no longer an ethical judgement call – it is an obligation with fines attached.

Leads lose their intent to buy within minutes, while organizations still operate in hours and days. The result is a leaking pipeline – even when both the marketing and the sales work are done well.

The most important part of the customer journey is still the most fragile: the conversation between customer and store.
