Support for Cisco Unified IP Phone 6901 Cisco Unified IP Phone 6901 is a new IP phone with keypad similar to other basic Cisco IP phones but this phone does not have display, speaker phone, or head set jack. This phone supports only SCCP protocol. Features such as Park, Unpark, Call Pickup, Group Call Pickup, Direct Transfer, Call Forward All, and Join are not supported as softkeys are not provided for these features. These features are supported only from Cisco Unified Communication Manager. Cisco Unified IP Phone 6901 is a one line device and can support two calls per line. So, features such as Join Across Lines and Direct Transfer Across Lines cannot be supported by these devices. One of the limitations of this phone is that to intiate or answer a call, the phone must be off-hook. If the phone is on-hook and the user initiates or answers a call, JTAPI throws InvalidStateException to the application with error code as CiscoJtapiException.OPERATION_NOT_AVAILABLE_IN_CURRENT_STATE. Another limitation is that Cisco Unified IP Phone 6901 does not accept XSI objects from applications, but if the application calls sendData() API for these phones, JTAPI throws an exception for the request to the application with the error code as CiscoJtapiException.COMMAND_NOT_IMPLEMENTED_ON_DEVICE.
