<p class="MsoNormal">If both Verto/SIP or webRTC/RTP are supported, is either more ideal?

<p class="MsoNormal" style="text-indent:.5in"><u></u> <u></u></p>
<p class="MsoNormal" style="text-indent:.5in">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.<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">I see there are various RFCs for text over RTP and text over RTCDataChannel in webRTC, but not sure if FreeSWITCH supports any of these.<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">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 RTCDataChannel?<u></u><u></u></p>
