Getting Started

This document explains how Grandstream GDMS (Grandstream Device Management System) is used in environments where DIDforSale is the SIP trunking provider. It clearly distinguishes between:

  • SIP trunk configuration on a PBX either CloudUCM (recommended) or on‑prem UCM

  • SIP account provisioning directly to devices via GDMS UC (limited to only few Grandstream devices with no PBX level features)

The goal is to provide administrators with a clear, correct, and repeatable integration approach.

It covers:

  • SIP account creation at DIDforSale

  • SIP trunk setup in the Grandstream PBX via GDMS

  • Inbound & outbound routing

Prerequisites

Before beginning, gather these from your DIDforSale account:

  • SIP Domain / Server (example: lxy.didforsale.com)

  • SIP Username / ID (example: 100xxxxxxx)

  • SIP Password (provided by DIDforSale)

  • Assigned DID numbers for inbound calls and outbound caller ID

  • GDMS Account

  • CloudUCM or on‑prem UCM added to GDMS

  • Added Grandstream devices, supported by GDMS

For instruction on creating a SIP account with DIDForSale follow link below.

Creating SIP Account

Log In to Grandstream GDMS

  1. Go to the GDMS dashboard: https://www.gdms.cloud/uc/dashboard

  2. Log in with your admin credentials.

Your CloudUCM instance should already be visible in GDMS. If not, add it following the GDMS device onboarding process.
