Cisco IP Phone-to-Cisco IP Phone Exchange of Skinny Station Messages during Call Flow

The following figure shows a sample exchange of messages between two Skinny Stations. The Skinny Station, or Cisco IP Phone, initiates a connection to the Cisco CallManager, and then Cisco CallManager performs digit analysis before opening a control session with the destination Skinny Station. As the following diagram indicates, the Skinny Station messages are written using simple English so they can be readily understood by end-users. Because of this, these messages are not explained in this section. However, these call flow Skinny Station messages are explained in more detail in later sections when traces are being examined.
