There are two ways to configure speed dial buttons on a Cisco SPA50x or SPA525 phone:
- Define them in the provisioning file
- Set them up directly from the phone itself
Provisioning file:
Set up directly:
- Have the user hold down an unused line key for 4 seconds
- They will be prompted to enter the button name and the number to be stored
