Phone Numbers

Phone numbers are assigned to your assistants. You can purchase numbers directly inside PulsyAI, or import existing numbers from Twilio, Telnyx, or your own carrier via SIP trunk. All numbers are managed under Numbers in the main menu.

E.164 Format

All imported phone numbers must be entered in E.164 format. This means the number starts with a + sign, followed by the country code, followed by the number — with no spaces, dashes, or parentheses.

Buying a Number In-App

The fastest way to get a phone number is to buy one directly inside PulsyAI through the built-in store. No external provider account is required.

Two Ways to Import a Phone Number

There are two entry points to open the import modal.

​

Option 1 — From the Numbers section

Navigate to the Numbers section in the left sidebar. This is the dedicated area for managing all phone numbers across your account. Once inside, you will land on the Numbers page where all your existing numbers are listed. Click Import to open the import modal.

​

Option 2 — From within an AI Assistant

You can also import a number directly from inside an assistant. Open the assistant, go to the Call Flows tab, and you will find the option to assign or import a phone number from there. Click Import to open the same import modal.

Twilio

In the import modal, select the Twilio tab. Fill in the following 4 fields: Here is where to find each value in your Twilio account.

​

Step 1 — Purchase a phone number in Twilio

Before importing, you need an active phone number in your Twilio account. In the Twilio console, go to Develop → Phone Numbers → Buy a Number. On the search page, filter by country, and optionally enter specific digits or an area code to narrow results. Click Search to see available numbers. Before clicking Buy, make sure the number shows the Voice (📞) capability icon — this confirms the number can handle calls. Once you find the right number, click Buy to purchase it. A confirmation screen will appear — click Buy once more to confirm the purchase. Once purchased, you will be taken to your active numbers list. Copy the phone number shown (highlighted in the screenshot) and paste it into the Phone number field in the PulsyAI import modal. Then click Configure to access the number’s settings. Inside the number’s configuration page, click Properties. Your Phone number SID is displayed there — copy it and paste it into the corresponding field in PulsyAI.

​

Step 2 — Get your Account SID and Auth Token

Navigate to the Account Dashboard in your Twilio console. Your Account SID and Auth Token are both displayed there. Click the copy icon (□) next to each value to copy them, then paste them into the corresponding fields in PulsyAI.

​

Step 3 — Save in PulsyAI

Once all four fields are filled in, click Save to complete the import.

​

Step 4 — Select the number and assign it to your assistant

Your imported number now appears in the dropdown. Select it to attach it to your AI agent — and that’s it, the number is live.
