Hello Cisco community I recently purchased six 8861 Cisco phones from Amazon 2 of the devices requiring the license activation code, and the seller is not providing them, I reached out to Cisco they said the customer is not affiliated with them, is there a way to get the activation code from the other devices or each device has it is own license, I am stuck with the devices can't do anything

devices serial number:FCH26372WYL AND FCH26372UEA
please help thank you.
