This appendix covers call signaling protocols and application protocols included in Cisco CallManager. Call signaling protocols support communication with trunks and endpoints, and application protocols enable the development of additional applications that complement CallManager functionality.
CallManager uses the following signaling protocols to communicate with its devices:
Signaling protocols provide an agreed-upon set of rules that define the format of messages used to transmit information and commands between devices.
This chapter addresses each of the signaling protocols in detail in the following sections:
