Check out our phone review for the Grandstream DP750 and DP720 HERE
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
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. To locate the IP address of your phone, select menu and then status. The IP address will be located on that informational page.
Step 3: Find the appropriate Profile
Click on your chosen Profile on the sidebar and enter the following information:
Profile Active: Yes
SIP Server: example.onsip.com
Prefer Primary SIP Server: No
Outbound Proxy: sip.onsip.com
Step 4: Enter credentials in SIP Account Settings
Click on 'Settings' in the top bar. Then click on 'SIP Account Settings' on the side bar. Enter the information that you gathered in Step 1 into the fields. Set the profile to 'Profile 1'.
Step 5: Choose the Handset Line Settings
Click on 'Handset Line Settings' on the sidebar. Handsets 1,2,3,4,5 can all be configured with the account you registered in Step 4.
