Overview

Call Permissions are settings within a telephony system that control the types of calls users can make. These permissions are crucial for managing costs, ensuring security, and enforcing organizational policies. This article explains the different types of call permissions, their use cases, benefits, and how to implement them effectively.

Solution

SIP Internal Calls

This permission allows users to make calls within the organization's internal network using the Session Initiation Protocol (SIP). SIP is a signaling protocol used to initiate, maintain, and terminate real-time communication sessions over IP networks, such as voice and video calls.

PSTN Local Calls (No International)

This permission enables users to make calls to local telephone numbers via the Public Switched Telephone Network (PSTN) but restricts them from making international calls.

International Calls (Int)

This permission allows users to make international calls over the PSTN. It includes all the capabilities of PSTN local calls, with the added ability to dial numbers outside the country.

Why Call Permissions Matter

By setting appropriate call permissions, organizations can significantly reduce telephony expenses, limit potential abuse of the phone system, ensure employees have the necessary access to perform their duties effectively, and help in adhering to legal and regulatory requirements concerning telecommunications.

Implementing Call Permissions

Assign permissions based on job roles, regularly review call logs to detect and address any misuse, and inform users about their call permissions and the reasons behind any restrictions.

Summary

Understanding and configuring call permissions like SIP internal calls, PSTN local calls, and international calls is essential for effective telephony management. It allows organizations to control costs, enhance security, and ensure that communication aligns with business needs.
