An originating user equipment (UE) that initiates a communication session as a real time text (RTT)-based communication may be configured to automatically downgrade the communication session in response to identifying one or more attributes of a response to a session request that indicate a communication session cannot be established with a full set of features requested by the user. For example, the originating UE can determine that a response to a session request indicates at least one of (i) an inability to establish the communication session, or (ii) an ability to establish the communication session without support for the exchange of the non-voice content via the RTT media stream. Based on this determination, a communication session can be established that does not support the exchange of the non-voice content via the RTT media stream. In this manner, rich RTT features are sacrificed in order to connect the user.
