Classes

RttParameters

RttReceiver

This class handles Real Time Protocol (RTP) packets containing Real Time Text (RTT, RFC 4103) and notifies the user of this class when complete messages are available. A complete message may be one character or several characters.

This class handles RTT redundancy as specified in Section 4.2 of RFC 4103 and is capable of recovering the original message even if there are dropped RTP packets.

This class supports receiving characters from a mixer-aware remote endpoint as described in RFC 9071 RTP-Mixer Formatting of Multiparty Real-Time Text.

RttSender

This class manages the sending side of a RTT media session. See RFC 4103. This class manages the transmission of redundant or non-redundant RTP packets containing RTT payloads based on the timing requirements specified in RFC 4103.
