Why aren't the keys on the phone doing anything?

The key pad on a phone can be locked and unlocked by following these steps:

  • Press and hold the * key.  
  • When deactivating the lock feature, the screen may have a prompt for a password. Press “OK” without entering a password, and the keypad will unlock.

Note: This applies to Grandstream series IP phones.
