Upgrading Your Phone's Firmware

Cisco Small Business IP Phone SPA 50X User Guide (SPCP)
On models with no screen, such as the Cisco SPA 501G, the lines should glow
green and you should hear a dial tone when picking up the handset or pressing the
speakerphone button.
If the phone does not start, confirm your installation and connections. If these are
correct, try unplugging the phone and plugging it back in again. If you still don't see
the display, then contact your phone administrator or Internet Telephony Service
Provider (ITSP).
The phone firmware is upgraded automatically from the Cisco Smart Business
Communications System (SBCS), according to the administrative settings.
