How to Manage Your Caller ID (CLI) for Better Connection Rates

Caller ID, or CLI (Calling Line Identification), is the information shown on a phone screen during a call. Whether you are calling a customer across town or a partner across the globe, your Caller ID is your "digital handshake." A clear, recognizable ID builds trust and ensures your calls are answered.

Frequently Asked Questions (FAQ)

1. Outbound Caller ID

Outbound Caller ID is the phone number your recipient sees on their device. This works across:

• Desk Phones: Standard office hardware.
• Softphones: Computer-based calling apps.
• Mobile Apps: Used by remote teams and field staff.

2. Caller ID for Incoming Calls

Inbound Caller ID tells you who is calling before you pick up. For businesses, this allows staff to provide a personalized greeting, improving the customer experience from the first second of the call.

3. Local CLI & International Compatibility

"Local CLI" refers to making calls within the same country using a local number. While the global standard (E.164) works for most calls, some international carriers may not display "foreign" numbers correctly.

AVOXI provides local Caller ID for many high-traffic regions, including:

• Europe: United Kingdom, Germany, Ireland, Spain, Italy.
• North America: United States, Canada.

Note: We work to ensure your number displays correctly, but international carrier regulations mean that 100% delivery cannot be guaranteed for every single global destination.

4. International Caller ID Restrictions

Global telecommunication laws are strict. When calling across borders, your number might be modified by a local provider in the destination country. This is often done to prevent "spoofing" (fake calls).

To maintain a high reputation:

• Be Consistent: Avoid changing your outbound numbers too often.
• Use Local Numbers: Whenever possible, call from a number within the same country as your recipient.
• Register Your Name: In the US and Canada, ensure your CNAM (Caller Name) is registered with your business name.

Frequently Asked Questions (FAQ)

Q: Why is my call labeled as "Spam Likely"?

A: This happens when a number makes too many calls in a short period or receives many "hang-ups." To prevent this, rotate your outbound numbers or use Intelligent Caller IDto match your number to the recipient's region.

Q: Can I show my business name instead of just a number?

A: Yes, through a service called CNAM. Note that this is primarily supported in the US and Canada. For international calls, the number is the most reliable way to identify yourself.

Q: How do I change my outbound number in the dashboard?

A: You can set your "Default Outbound ID" in your user settings. For team-wide changes, an administrator can assign specific numbers to specific groups.
