Their customer portal is the central hub for managing services, billing, numbers, and support. Whether you’re a new user or an experienced administrator, understanding every section in the left sidebar is key to getting the most value from your account.
In this in-depth guide (over 1,800 words), I’ll explain every available function shown in the sidebar based on the actual portal interface. I’ll include step-by-step instructions, real-user tips, and detailed explanations so you can navigate confidently.
SIP.US Customer Portal Guide: Complete Walkthrough of All Features

Key Features:
