After trying MRCPv1 - I don't think anybody out there is using Nuance for TTS remotely / externally! The audio is always blank / silence(both Nuance and FreeSWITCH seem to think it is working ok). I can get it to work with Nuance on localhost/127.0.0.1, but I believe there is a problem with FreeSWITCH/UniMRCP determining the correct rtp-ip when in MRCPv1 mode when using a server other than localhost. As shown in earlier posts in this thread, I can get it to work with MRCPv2 on the same external server. Regardless of all of these settings (client-ext-ip , client-ip , rtp-ip , rtp-ext-ip being set to an IP address other than 127.0.0.1, RTP is still trying to use 127.0.0.1, although RTSP is using the external IP address provided. mpf_rtp_stream.c from uniMRCP returns several references to 127.0.0.1 although it should not: mpf_rtp_stream.c:495 () Close RTP Receiver 127.0.0.1:4018 <- 10.0.0.67:7914 [r:0 l:0 j:0 d:0 i:0] and mpf_rtp_stream.c:1294 () Send Compound RTCP Packet [BYE] [76 bytes] 127.0.0.1:4019 -> 10.0.0.67:7915 mpf_rtp_stream.c:1306 () Failed to Send Compound RTCP Packet [BYE] [0 bytes] 127.0.0.1:4019 -> 10.0.0.67:7915 I believe this explains why I cannot hear the audio that is generated, as it should be using a 10.0.0.x IP address to receive and sent over RTP. To be safe I also changed the external_rtp_ip in vars.xml, but that hasn't fixed the issue either. Does anybody know where mpf_rtp_stream.c is getting this RTP IP Address from? Why does it insist on 127.0.0.1 despite all settings saying otherwise?

You can also try MRCPv1 (RTSP) and see if there is better performance. Using SIP to set up an MRCP session is silly.

However, I am seeing a call use up 2,3,4 (etc) like it is not releasing the connection/license. 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). <!-- enable/disable rtcp support --> <param name="rtcp" value="1"/> <!-- rtcp bye policies (rtcp must be enabled first) 0 - disable rtcp bye 1 - send rtcp bye at the end of session 2 - send rtcp bye also at the end of each talkspurt (input) --> <param name="rtcp-bye" value="2"/> <param name="rtcp-tx-interval" value="5000"/> Ideas?
