SDP Payload Types

The configured dynamic payloads are used for outbound calls only where the
SPA9000 presents the SDP offer. For inbound calls with a SDP offer, the SPA9000
follows the caller dynamic payload type assignments.
The SPA9000 uses the configured codec names in its outbound SDP. The
SPA9000 ignores the codec names in incoming SDP for standard payload types (0
– 95). For dynamic payload types, the SPA9000 identifies the codec by the
configured codec names. Comparison is case-insensitive.
