1. An originating user equipment (UE) comprising:

  • a processor; and

    memory storing computer-executable instructions that, when executed by the processor, cause the originating UE to;

    receive user input requesting to establish a communication session that supports an exchange of (i) voice content via a voice media stream and (ii) text content via a real time text (RTT) media stream;

    send, over a telecommunications network, a session request to establish the communication session;

    receive, over the telecommunications network, a response to the session request;

    determine that the response to the 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 text content via the RTT media stream;

    establish, without user intervention, a new communication session or a downgraded version of the communication session, wherein the new communication session or the downgraded version of the communication session does not support the exchange of the text content via the RTT media stream and instead supports an exchange of the non-voice content via an alternate form of text messaging, the alternate form of text messaging being a form of text messaging different from RTT; and

    display, on a display of the originating UE, a visual notification indicating a lack of support for the exchange of the text content via the RTT media stream.
