Before beginning.

• Make sure you’re using the new ethernet cable provided with the phone.
• Often times using the same port the old Cisco phones were connected too can cause an interference, try to use another available port. 
• Make sure all old Cisco phones and devices are unplugged completely and set aside for later pickup.

New Phone Set Up

• Unpack the phone and connect the base
• Locate the best location to set the phone up that is easily accessible to the sales team
• The only cable that should be connected to the phone is the one coming from the wall (ethernet cord), which should be inserted into the Internet port on the back of the phone. (DO NOT USE THE POWER CORD)
• Give the phone a moment to power up
• The phone should boot up with a green light and provide the store name and extension on the screen
• You’re all set!

Troubleshooting (Phone Alone) 

• Disconnect the power adapter cable from the phone (if power adapter was used)
• Unplug the Ethernet cable
• The only cable that should remain connected to the phone is the one coming from the wall, which should be inserted into the Internet port of the phone.
• Give the phone a moment to power up
• The phone should boot up with a green light and provide the store name and extension on the screen (If the phone does not boot up – the ethernet port is not functioning, locate another available port)

Troubleshooting (With PC)

Still Not Working 

• If the phone fails to power up even when connected to the Ethernet cable leading to the internet port, it indicates that the port is not functioning. If you have no other available ports then a technician will be required to assist. 
• Please attempt a different Ethernet cable that was previously used with the Cisco phone. The phone should power up if connected to the correct Ethernet cable associated with the Cisco phone that was there previously.If the phone still does not establish an online connection or displays a "no service" message, 
• proceed with a factory reset. The instructions for performing a factory reset on Yealink phones are as follows: Menu->Advanced (password is admin)-> Reset Config.
• If the phones are still displaying “No Service” message, kindly contact Akshay Sharma at aksharma@dufresne.ca, providing your store address, availability, and cell phone number.
