The Phone System App. Account - Settings - Caller ID Subtab

Description: Here, you have the option to configure the Caller ID Name and Number for in-house, outgoing, and emergency calls.

Caller ID is a service that displays the caller's phone number and name on the recipient's phone or device before the call is answered. It enables the recipient to identify the caller and decide whether or not to answer the call.

The parameters in this subtab are categorized into three sections:

1. In-House Calls
2. Outbound Calls
3. Emergency Calls

In-House Calls  

By filling out these fields, you can specify a personalized Caller ID Name and Number for your account's in-house calls.

Outbound Calls  

In this section, you can personalize the Caller ID Name and Number for your account's outbound calls.

Emergency Calls  

Within this section, you can set up the Caller ID Name and Number for emergency calls and activate the "Pass realm in INVITE" feature.

In the context of setting up Caller ID, the term "Pass realm in INVITE" refers to functionality that allows the caller's Session Initiation Protocol (SIP) realm to be included in the SIP INVITE message. 

The SIP INVITE message is used to initiate a communication session between multiple parties. By adding the caller's SIP realm in the INVITE message, the recipient can validate that the call is coming from a legitimate source.

When the "Pass realm in INVITE" feature is enabled, the caller’s SIP realm is included in the INVITE message as a parameter. This allows the receiver to verify the authenticity of the call and helps to prevent fraudulent or spoofed calls. Enabling the "Pass realm in INVITE" feature can be done by clicking your mouse on the checkbox.

Once you have inputted data into the fields, do not forget to click on the "SAVE" button to apply the changes. 

The Phone System App will display an icon of an exclamation mark within a green circle next to any fields that have been modified.

The Phone System App will notify you that leaving the page will result in the loss of any unsaved changes.
