Fail-safe Number
We strongly recommend adding a Fail-safe number for each of your Tracking Numbers. This is the backup receiving number where calls will go if CallTrackingMetrics is down and cannot follow advanced routing options.
Fail-safe numbers are set up at the Tracking Number level. To configure, go to Numbers > Tracking Numbers. Click “edit” next to the Tracking Number where you wish to add a Fail-safe number. Go to the Fail-safe Number area of the editing page. Once you enter your Fail-safe number, you can choose to also save your Fail-safe number to multiple tracking numbers so you don’t have to do them one by one.

When designating a Fail-safe number consider the following parameters:
- Your Fail-safe numbers should not be a CTM number.
- While you may use the same Fail-safe Number for multiple Tracking Numbers, you will need to add that information into each individual Tracking Number on your account.
- If you are a high volume customer, we recommend you have several Fail-safe numbers used across your Tracking Numbers to handle call volume.
