Skinny Station Registration Process
Cisco IP Phones communicate with Cisco CallManager using the Cisco Skinny Station Protocol.
The registration process allows a Skinny Station, such as a Cisco IP Phone, to inform
Cisco CallManager of its existence and to make calling possible. The following figure shows the
different messages that are exchanged between the Cisco IP Phone (the "station") and the
Cisco CallManager.
