SDP Payload Types

The configured dynamic payloads are used for outbound calls only where the IP
phone presents the SDP offer. For inbound calls with a SDP offer, the IP phone
follows the caller dynamic payload type assignments.
The IP phone uses the configured codec names in its outbound SDP. The IP phone
ignores the codec names in incoming SDP for standard payload types (0 – 95). For
dynamic payload types, the IP phone identifies the codec by the configured
codec names. Comparison is case-insensitive.
