Set up SIP users

Last updated on Oct 12, 2026

A SIP user is a login that lets a desk phone, a softphone app or your own phone system make and take calls on SiriusTel. You need a SIP trunk or a Cloud PBX plan first.

Create a SIP user

  1. Open your phone console from the shop.
  2. Go to the SIP users section.
  3. Add a user with a clear name, such as reception or sales-01.
  4. Set a long, random password. Never reuse one.
  5. Save.

Connect a phone

Enter three things in the phone or app: the SIP server address shown in your console, the SIP username and the password. Then make a test call.

Connect your own phone system

If your phone system has a fixed IP address, add it under IP access in the console. Calls from that address are then accepted without a password. Add only addresses you own.

How many calls at once

Your plan sets your number of channels. Each channel carries one call at a time. Need more? Add channels in the shop.

Stay safe

  • Use one SIP user per device.
  • Delete users you no longer need.
  • Check your call history for calls you do not recognise, and tell us at once in the chat.
