Configure the SDP Payload Types
Configured dynamic payloads are used for outbound calls only when the Cisco IP Phone presents a Session
Description Protocol (SDP) offer. For inbound calls with an SDP offer, the phone follows the caller's assigned
dynamic payload type.
The Cisco IP Phone uses the configured codec names in outbound SDP. For incoming SDP with standard
payload types of 0-95, the phone ignores the codec names. For dynamic payload types, the phone identifies
the codec by the configured codec names (comparison is case-sensitive).
