Step 1: Gather information for each user.

Each user has a set of credentials which will be needed to configure each phone. For each phone that you are configuring, obtain the following:

  • SIP Address (Address of Record)
  • SIP Password
  • Auth Username
  • Username
  • Proxy/Domain

You can find this information in the user detail pages under the Users tab in the Phone Configuration section.

Step 2: Log into your Grandstream phone through a web browser

When your phone is powered on and connected to your LAN, use a browser to navigate to the IP address of your phone. The IP address of your phone should automatically display on the screen. Password "admin". Once you've logged in select "Account 2".

Step 3. Enter your user information from Step 1.

For most setups, you will need to simply configure "Account 1". If you are trying to configure multiple users or multiple line appearances, you can repeat the steps below for each of the identities you are configuring.

  • Account Active: Yes
  • Account Name: Whatever you would like others to see when you call them.
  • SIP Server: Domain
  • Outbound Proxy: sip.onsip.com
  • SIP User ID: Username
  • Authenticate ID: Auth Username
  • Authenticate Password: SIP Password
  • Name: Whatever you would like others to see when you call them.

Account Setup

Under Network Settings, set Outbound Proxy to 'sip.onsip.com', DNS Mode to 'A Record', and NAT Traversal to 'Keep Alive'.

Network Settings

Step 4. Confirm that your phone is registered.

In the Admin Portal click on User tab (left).  You will see a green "online" notation next to each user with a registered phone.
