This easy-to-configure feature automatically selects the best caller ID based on who the call is being made to, regardless of call origination, helping to:
- Increase call answer rate with familiar numbers
- Improve agent efficiency by removing the manual work of changing CLIs between calls
- Streamline multi-platform configuration to a single location for AVOXI numbers

How does it work?
Configuration
Enable feature on SIP Trunks
- Navigate to SIP Integrations
- Select the Trunks tab
- Select the desired Trunk and view settings
- Enable Intelligent Caller ID
-
Create one or more Caller ID Groups
- All calls placed through this trunk will apply the Intelligent CLI logic to select the best Caller ID
- Note: If a call does not match the criteria defined by one of the Caller ID Groups, it will maintain its original Caller ID

Configure Caller ID Groups
Caller ID Groups allow you to manage multiple distinct pools of Caller IDs from a single trunk. When a call goes through an Intelligent CLI-enabled trunk, the feature checks to see if it meets the criteria for any of the configured Caller ID Groups on the trunk, at which point a CLI will be selected from the defined list of CLIs.
There are two ways to configure a Caller ID Group:
-
Caller ID Group Library
- Navigate to SIP Integrations
- Select the Caller ID Groups tab
- Select the “Add Group” button
- Any Caller ID Group you create can be used across any of your trunks
- Deleting a Caller ID Group will remove it from all trunks where it is being used
-
SIP Trunk Configuration Modal
- Within the SIP Trunk configuration modal, select “Add New”
- Select an existing Caller ID Group or Create a New One
- Caller ID Groups created within the SIP Trunk configuration modal will be added to the Caller ID Group library to be used by other SIP Trunks as needed
Caller ID Group configuration details:
- Give the Group a Friendly Name for easy reference
-
Define the Group Selector
- This is how we will know which pool of Caller IDs to choose from for that particular call
-
Choose one of the three Selector Types below:
-
Prefix
- This is a short code dialed before entering the number you are dialing
- The prefix can be preceded by a * or you can create a prefix code without the *
- We advise that you use 2-4 digits for your prefix code
-
Caller ID
- This refers to the original CLI sent to us from your UCaaS/CCaaS platform
- When you use a Caller ID as your selector type, the agent must simply select that CLI when they place their call
- We will then replace it with a CLI from your defined list if a better CLI is available
-
SIP Header
- With the SIP Header selector type, we will look for the defined SIP Header and Value in the call metadata
- The SIP header must include the ‘x-AVOXI’ prefix
- If no Group Selector is defined, this rule will apply to all calls that do not fit the Selector criteria defined by the other Caller ID Groups
-
Prefix
-
Select Your Caller IDs
- This is the list of Caller IDs Intelligent CLI will choose from for this Group
- If left blank, we will maintain the original Caller ID

Emergency Service Calls
When making calls to an emergency service number, we will present the original outbound caller ID that was passed to us.
