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).
