A SIP account (Session Initiation Protocol account) is simply a digital phone line that lets you make and receive phone calls over the internet instead of using traditional phone cables. It comes with a username, password, and host that allow your computer or smartphone to connect to a phone network.

How to order and where can you find your SIP account details?

You can obtain a SIP account completely free of charge once you have activated your number. In the "Additional" section of your personal account, click on the "SIP accounts" tab.Then click the "Request a SIP account" button. The SIP account will be provided within 24 hours. 

You can find your username, password and host in the "SIP accounts" tab in the "Additional" section of your personal account. Click “i” to view your SIP account details.

These details will be used for illustrative purposes in all further instructions. Please enter the details from your own SIP account instead.


How to set up call forwarding to a SIP?

  1. In the call forwarding settings, enter SIP/username@username. 
  2. Click "Save".

For example, if the username for the SIP account is 0000000000, you need to enter SIP/0000000000@0000000000 in the forwarding field.

To use a SIP account from a third-party provider (not from us), enter in the call forwarding settings: SIP/SIP_ID@provider.com.


Softphone configurations

Using any SIP softphone (an application for calls over the Internet) will give you the ability to answer incoming calls that come to the rented number completely free of charge. 

To configure each of them, you will need the following details from your SIP account: 
Your Username (0000000000)
Your Password (111111)
Host (sip.telecomax.net)
and, in rare cases, Transport (UDP)

These details will be used for illustrative purposes in all further instructions. Please enter the details from your own SIP account instead.

You can forward calls to your Android, iOS or computer using these apps.
