We are wondering if FreeSWITCH supports sending andreceiving text messages between Verto/webRTC to/from backend SIP/RTP systemsthat conferenced together?   1)     We want to use this to send commands from theweb browser to the backend systems, for example: a.       “heybackend system, please turn on the ASR to start listening.”   2)     We also wonder if FreeSWITCH supports sendingcommands from the backend to the frontend (web browser), for example: a.       “heyavatar, here are some visemes to tell you how you should move your lips, arms,… at the same time as playing this audio”   If both Verto/SIP or webRTC/RTP are supported for sending text, is eithermore ideal?    For instance, if the text/commandsare over RTC then maybe we can use one clock for all RTP streams and/or RTPsessions and use the RTP timestamps to synchronize the commands withaudio/video.  Or maybe Verto/SIP is better for commands.     I see there are various RFCs for text over RTP and text over webRTC, but not sure if FreeSWITCH supports any of these.   I also see FreeSWITCH mod_verto  support text messages,but not sure if FreeSWITCH sends these to/from SIP (e.g. maybe via SIMPLE SIP)or via text over RTP?     Robert
