Preserve CLI

Preserve CLI (Calling Line Identification) keeps the original caller’s phone number visible when a call is forwarded to another destination.

When Preserve CLI is disabled, the final destination may display the forwarding number instead of the original caller’s number. Enabling this feature helps recipients identify who originally placed the call, even when it passes through call forwarding.

Enable Preserve CLI

Follow these steps to enable Preserve CLI:

1. Log in to your 2talk account.
2. Go to your left panel >Numbers.
3. Select the phone number you want to configure.
4. Navigate to Inbound > Preserve CLI.
5. Turn Preserve CLI On.
6. Click Save to apply your changes.

Preserve CLI Example

Consider the following call flow:

1. Jack calls Wendy.
2. Wendy has Call Forwarding enabled to redirect calls to Roger.
3. With Preserve CLI enabled: Roger sees Jack’s caller ID, showing the original caller’s number.
4. Without Preserve CLI: Roger may see Wendy’s phone number instead of Jack’s.

This feature helps maintain the original caller ID information when calls are forwarded to another destination.

Note: The caller ID displayed at the final destination may also depend on downstream carrier support and network settings.
