Grandstream

If your phone is stuck on "initializing," this is normal when the phone is trying to register itself. However, if it stays stuck for a long time, it means it hasn’t connected to our platform. Here are the common scenarios and solutions:

Go to Accounts > Account 1 > Call Settings

Fill in alert-internal for Matching rule and choose which ringtone should be played next to it.

This is usually because of the Caller ID Header setting. Change it from From SIP Header to Remote Party-ID SIP Header in Freedom – and possibly on your device too. That should show the correct number again.

Use BLF (Busy Lamp Field) with an extra display on your Grandstream. It shows who’s available or on a call with simple lights. Set it up under Programmable Keys > Extension Boards.

Log into Freedom and check your VoIP account. If there’s a lock icon inside the green status dot, your connection is encrypted. No lock? It’s not secure. Make sure encryption is forced in Freedom and that your phone uses TLS and SRTP.

1. Press the MENU button to bring up the keypad configuration menu.
2. Select "System" and enter.
3. Select "Operations → Factory Reset".
4. A warning window will pop out to make sure a reset is requested and confirmed.

Press the "Yes" Softkey to confirm and the phone will reboot, or “No” Softkey to cancel the Reset. Check out this video for more help
