Workplace CC for Windows supports the Agent Greetings feature. However, it works differently enough from how the J-series phones work that agents cannot move between "devices" and use the same greetings.
1) Workplace only supports UCaaS mode (SET AGTGREETINGSTAT 2), not agent mode (SET AGTGREETINGSTAT 1), for the greetings so the <ext>_CCdata.txt agent greeting config file is named for the station extension and not the agent.
2) When recording a greeting file, Workplace creates a WAV file with the name GREETING_<TIMESTAMP>.wav. The J-series uses <agentID>_<index>.wav. Using the more generic GREETING_<TIMESTAMP>.wav makes wav file management more difficult and increases the likelihood of naming conflict.
