Recent Airport firmware update 7.6.7 causing problems with VoIP

It might be helpful to know what VoIP you are using and what kind of problem the update is affecting your VoIPs.

My MagicJack & NetTalk lines are working fine.

Unfortunately, there is always a possibility that something may go awry when updating firmware. One option is to downgrade to an earlier version.

To manually download and install previous (earlier) versions of firmware...

• Open AirPort Utility.
• Select the base station, and then, click on Edit.
• A new window will appear. Hold down the Option key and hover the mouse cursor over the firmware build number. The firmware version number should now be highlighted.
• While still holding down the Option key, click on highlighted number to see all the firmware versions that are available.
• Click on the one you want to downgrade to.
• A dialog box will pop-up to let you know that the base station will be unavailable during the downgrade process.
• Choose either "Continue" to continue with the downgrade OR choose "Cancel" if you decide not to.
• If you choose to continue, allow the firmware to be downloaded, installed, and for the base station to restart.
