<p class="ydp6c058c94yiv7784026944ydpcc87bb17MsoNormal">We are wondering if FreeSWITCH supports sending and
receiving text messages between Verto/webRTC to/from backend SIP/RTP systems
that conferenced together?</p>

</span></span></span>We want to use this to send commands from the
web browser to the backend systems, for example:</p>

backend system, please turn on the ASR to start listening.”</p>

</span></span></span>We also wonder if FreeSWITCH supports sending
commands from the backend to the frontend (web browser), for example:</p>
<p class="ydp6c058c94yiv7784026944ydpcc87bb17MsoListParagraph" style="margin-left:1in;"><span><span>a.<span style="font-style:normal;font-weight:normal;font-stretch:normal;font-size:7pt;line-height:normal;font-size-adjust:none;"> </span></span></span>“hey
avatar, here are some visemes to tell you how you should move your lips, arms,
… at the same time as playing this audio”</p>
<p class="ydp6c058c94yiv7784026944ydpcc87bb17MsoNormal"> </p>
<p class="ydp6c058c94yiv7784026944ydpcc87bb17MsoNormal">If both Verto/SIP or webRTC/RTP are supported for sending text, is either
more ideal? </p>
<p class="ydp6c058c94yiv7784026944ydpcc87bb17MsoNormal" style="text-indent:.5in;"> </p>For instance, if the text/commands
are over RTC then maybe we can use one clock for all RTP streams and/or RTP
sessions and use the RTP timestamps to synchronize the commands with
audio/video. Or maybe Verto/SIP is better for commands.

<p class="ydp6c058c94yiv7784026944ydpcc87bb17MsoNormal">I see there are various RFCs for text over RTP and text over webRTC, but not sure if FreeSWITCH supports any of these.</p>
<p class="ydp6c058c94yiv7784026944ydpcc87bb17MsoNormal"> </p>
<p class="ydp6c058c94yiv7784026944ydpcc87bb17MsoNormal">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?</p>
