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.
CountryExample
United States / Canada+14385950345
United Kingdom+447911123456
France+33612345678
The country code +1 covers both the United States and Canada. Other countries use their own code, such as +44 for the UK or +33 for France.

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.
1

Open the Numbers section

Navigate to Numbers in the main menu.
2

Search for a number

Filter by country, and optionally enter specific digits or an area code to narrow results.
3

Purchase and assign

Select an available number and confirm the purchase. The number is added to your account, ready to assign to an agent.
Phone numbers purchased directly in PulsyAI can only be used for inbound AI agents — not outbound — as a security measure. To get a number for an outbound agent, import a number from Twilio or Telnyx, or connect your own carrier via SIP trunk.

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.

Telnyx

The Telnyx tab requires the following 5 fields:
1

Enter your Telnyx number in E.164 format (e.g. +14385950345).
2

The unique identifier for your phone number in Telnyx. Found under Numbers → My Numbers.

SIP Trunk

Importing a SIP trunk number is a two-part process:
1

Configure your SIP trunk

Before importing the number, go to SIP Configuration in the main menu and set up your SIP trunk connection. This is where you configure the SIP server credentials and routing.
2

Import the number

Once the SIP trunk is configured, go to Numbers → Import and select the SIP Trunk tab. Enter your phone number in E.164 format and complete the import.
The SIP Trunk tab in the Import modal only asks for the phone number. The SIP trunk itself must be fully configured in SIP Configuration first — otherwise the import will not connect correctly.
