Strengthening our infrastructure in Europe — a new data center in Spain

Zadarma is launching a new data center in Madrid. This is an important step in strengthening the European network, with powerful servers, high bandwidth, and modern software.

The data center is directly connected to the Espanix traffic exchange network, which ensures stable connectivity and minimal latency for customers in Spain and Portugal.

Important: Clients using a firewall need to allow the 185.45.154.0/24 network for proper service operation.

New Zadarma PBX feature: integration with AI platforms

Now Zadarma users can forward calls not only from virtual numbers but also from PBX extensions to AI platforms — Retell, ElevenLabs, VAPI, and others.

AI agents can easily connect to extensions and can support the team by answering calls in a queue, accepting transfers from employees, or functioning as an intelligent voicemail.

This expands the capabilities of voice bots and allows flexible call routing to any SIP URI.

The arsenal of AI agents has been expanded — Zadarma is now with ElevenLabs

As soon as ElevenLabs made integration possible, we quickly adapted and added support.

The voice AI agent from ElevenLabs is now available for receiving incoming Zadarma calls. The integration is already implemented and can be easily connected using a ready-made guide — no complicated setup.

This is another step in the development of Zadarma's AI capabilities: call automation, rapid response to new technologies, and expanded choice for businesses.

Zadarma app for MacOS

We’ve released a new version of the Zadarma app — it now runs on macOS with Apple M-series processors.

With the app, you can:

• Make calls via Zadarma SIP and PBX;
• Configure Caller ID and call forwarding;
• Send messages and monitor your balance;
• Use the built-in phone book.

The app is available on the App Store, and a detailed setup guide is available on the website.

New PBX feature and integration with AI service

Now, in the Zadarma virtual PBX, you can display the scenario name in the CallerName or play it as an audio file for the operator. This helps immediately understand, where the client called – which menu or scenario they reached. The name must contain only Latin letters or numbers.

Another important update is the extended integration with the VAPI AI service. Now, calls can be handled using an AI-powered voice bot, automatically interacting with customers and executing necessary scenarios without operator involvement. A detailed guide can be found here.

Additionally, we have expanded our integrations and added support for the Twilio service. The integration of Zadarma with Twilio allows you to route incoming calls from Zadarma virtual numbers and process them in Twilio, as well as make outgoing calls through Zadarma at competitive rates.

Multichannel verification via API: new methods in our interface

Recently, the API interface of Zadarma has been updated with verify methods for confirming phone numbers and emails. These new methods allow for instant sending of verification codes via SMS, call, or email, and receiving a response directly to the server

Two convenient methods have been added for verification via call: dictating the verification code and confirming the action by pressing a button on the phone.

Automation can be adapted to any scenario — from registration confirmation to two-factor authentication. The setup can be completed in just a few minutes using pre-built classes for working with the API and the provided instructions.

Elastic SIP Trunk for Retell AI and new capabilities in Zapier and HubSpot

We continue to improve integrations with popular services - now Zapier supports SMS sending, and HubSpot - a local number format for incoming calls.

Support for the Elastic SIP Trunk connection format has been added, allowing Zadarma to be used in Retell AI and similar services for both incoming and outgoing calls. (For calls with correct Digest authentication, arbitrary values are allowed in the From header).

How to connect artificial intelligence in Retell AI to Zadarma?

We have prepared a detailed guide to help you set up the integration quickly and start working.
