<div class=Section1>
<p class=MsoNormal>In connecting to Nuance Speech Server’s MRCPv2 for
text-to-speech (Nuance Vocalizer) using mod_unimrcp, a single phone call which
has several different TTS phrases should only use up 1 single simultaneous license.
However, I am seeing a call use up 2,3,4 (etc) like it is not releasing the
connection/license.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I looked this up and some forums have noted that Nuance “does
things wrong” and uniMRCP needs to send Nuance the “RTCP BYE”
to tell Nuance that it is done with the synthesizer speech. But I tried
that, and it still eats up the licenses. Within a couple of calls I’m out
of TTS ports and the calls fail (but they clear again after several more
seconds).<o:p></o:p></p>
