So apparently there is no support at all for the 9971 addon modules for the uc560. So here is a warning for anyone else the runs into this issue. Save yourselves the restocking fees on an un/half supported product.
Here is the response from TAC:
Two types of SIP Phones are supported:
• SIP Phones — CP-8961, CP-9951, CP-9971
These features are supported:
- Topology View
- Voicemail
- Auto Attendant
- Dial by name
- Blast group
- Dial Plan
- Normal Lines
These phones are not supported with Teleworker nor Multisite environments. There is no support for these phones in the Telephony Setup Wizard.
