RealtimeText IsCompising is not called.
Using the newest core, it seems like IsCompising is not called from the Core when a new RealtimeText character is received. I can however still send over RTP and negotiate RealtimeText over SIP/SDP (t140 and red).
This has been tested with the newest LinphoneCore and on both iOS and Android.
