3CX does not offer plans for 3CX communication systems. You have the flexibility to choose your SIP Trunk / VoIP provider to suit your needs and budget. You can use any SIP trunk, including existing lines. It is highly recommended to choose one of the supported SIP trunk providers

The 3CX mobile app is not a standalone app. You need to configure the 3CX communication system with extensions and SIP trunks. If you need help with this, please contact your 3CX partner.

If you are confident that this has happened; then the administrator will send you a welcome email to configure the 3CX app.

Or you can just:

  • Scan the QR code
  • Click the mobile device configuration file.

You are ready to use the 3CX app.

The benefits of trading in a 3CX Perpetual License for an Annual Subscription.

  • Enjoy it completely free in the very first year!
  • The annual license includes maintenance.

Immediate upgrade to the latest version. Simply log in to the 3CX Customer Portal, find your subscription, and click more. Select trade-in and follow the instructions.

The extension’s web client credentials can be found in the email titled “New 3CX User Account” sent by the 3CX administrator. This email also contains the voicemail PIN and QR code for the 3CX app. It will be sent to the 3CX administrator’s email address registered in the extension.

  • If you do not receive this email, you will need to send a “welcome email” with your extension number from your administrator.
  • If you have already configured the 3CX app, tap the app menu in the left corner. Then select Settings-> Resend Credentials.

Note: 3CX cannot send extension credentials. You will not be able to access the information and data of your company’s 3CX Phone System.

When deploying 3CX through the installer, administrator credentials are sent to the email address provided during license activation during deployment of the 3CX communication system. If you deploy 3CX through the Customer Portal, your credentials will only appear once at the end of the process.

3CX does not have access to your credentials. However, if you lose your credentials, you can recover them by following the instructions.

You can also restore your credentials from a backup. As a last resort, open a support ticket. We will support you.

This law has the following requirements:

  • 911 calls can be dialed without an area code.
  • If you receive an emergency call, you need to notify the appropriate person.

How do I configure 3CX to comply with Kari’s Law?

A step-by-step video guide is available that emphasizes the following:

  • Identify the emergency number and set it in 3CX Management Console> Settings> General> Emergency Number.
  • There is no extension number corresponding to the emergency number. Extensions such as 911 and 112.

Appropriate personnel who are notified of the required information when an emergency number is dialed (such as the dialed number or the extension to call an emergency service) can be notified in the following ways:

  • Chat
  • Email
  • Pre-recorded announcements on 3CX

If you or someone else tries to log in to 3CX more than once with the wrong credentials, 3CX will block access from that IP address. This is done to protect the 3CX communication system from future malicious demands. In this case, you will see the following message:

The IP address that was blocked and caused this ban could be one of the local IP addresses of your computer, IP phone, or mobile phone. When hosted, external IPs for Internet access are blocked. This will prevent all users using the same IP from accessing 3CX.

How to unblock:
To remove a blocked IP address:

  • Requires administrator access to the CX management console
  • Log in to the 3CX Management Console from another unblocked IP address. If 3CX is on the network, use another PC. If 3CX is in the cloud, use your mobile data plan (disable WiFi!).
  • After logging in, go to 3CX Dashboard-> Blacklisted IP
  • Find the IP in question (you may see a lot of legitimate blocked addresses here) and press Remove.

Prevent future blocks:

To prevent this particular IP from being banned in the future, remove the entry. Then whitelist the specific IP. Change Block to Allow to specify that this IP should be allowed. This is useful, for example, in a static field office. Use with caution as 3CX will no longer trigger the anti-hacking feature on this IP. Only allow trusted and trusted IP addresses.
