Last Line No Longer Available

What is “Last Line No Longer Available”?

The term “Last line no longer available” is a technical alert that typically surfaces on iPhones when you try to make a call. It essentially signals an issue with your device’s capability to initiate or maintain a call connection.

This could disrupt your important conversations and business communications, leading to frustration. This message generally stems from a network glitch, incorrect device settings, iOS bugs, or in some cases, even the device hardware.

Causes of “Last Line No Longer Available”

Several factors can contribute to the “Last line no longer available” message appearing on your iPhone. Here’s a more detailed look at the common causes:

Network Congestion: This is quite prevalent in areas with high user density. When too many users are trying to access the network simultaneously, it can lead to congestion, causing connection instability or failure.

Device Settings: Sometimes, misconfigured settings related to network connections might be causing the problem. An incorrect setting can prevent your iPhone from making or maintaining a call.

iOS Glitches: Software glitches are not uncommon and can often cause unexpected issues. In some cases, a bug in the iOS system could lead to this issue.

Firewall and Antivirus Restrictions: Security software, including firewalls and antivirus programs, are designed to block suspicious activity. However, they might sometimes interfere with legitimate network connections, causing issues like this.

Solutions to Fix “Last Line No Longer Available”

Follow these solutions carefully to fix “Last line no longer available” error:

Solution 1: Adding Exception to Windows Firewall

If you’re using your iPhone’s features on a Windows system with a firewall enabled, you may need to make an exception for it to work properly:

Step 1: Open the ‘Control Panel’ and navigate to ‘System and Security’, then ‘Windows Defender Firewall’.

Step 2: On the left pane, click ‘Allow an app or feature through Windows Defender Firewall’.

Step 3: Click the ‘Change settings’ button, which should enable you to edit the list of apps. Scroll down and find iTunes in the list.

Step 4: Ensure both ‘Private’ and ‘Public’ boxes next to iTunes are checked. Then, click ‘OK’. This allows iTunes to communicate freely through the firewall, ensuring smooth connectivity.

Solution 2: Adding Exception to Avast Antivirus

In case you have Avast Antivirus installed:

Step 1: Launch Avast and go to ‘Menu’ in the top right corner and then ‘Settings’.

Step 2: Under ‘General’, look for ‘Exceptions’.

Step 3: Here, click ‘Add Exception’, and in the space provided, enter the directory where iTunes is installed (usually it’s in the Program Files folder).

Step 4: Once you’ve entered the directory, click ‘Add Exception’ to save the changes. This should help Avast recognize iTunes as a safe application.

Solution 3: Adding Exclusion to Windows Defender

If you use Windows Defender as your primary security program:

Step 1: Go to ‘Settings’ on your PC and select ‘Update & Security’, then ‘Windows Security’, and finally ‘Virus & threat protection’.

Step 2: Under ‘Virus & threat protection settings’, click on ‘Manage settings’.

Step 3: Here, you’ll find an ‘Exclusions’ section. Click on ‘Add or remove exclusions’.

Step 4: Click ‘Add an exclusion’, select ‘Folder’, and add the iTunes installation folder

Solution 4: Adding Exclusion to Malwarebytes

If you’re using the cybersecurity program Malwarebytes, you might need to add iTunes to its whitelist to prevent interference:

Step 1: Open Malwarebytes and navigate to ‘Settings’.

Step 2: Click on the ‘Allow List’ tab.

Step 3: Click on ‘Add’, choose the option for ‘Folder’, then navigate to and select your iTunes installation folder.
