Hi Michael/Chris Did you find out what the problem was? We're seeing something similar. Thanks in advance David On Mon Mar 14, Michel Habib <michelhabib at gmail.com>wrote:

Sorry for the delay and thanks Chris, Please find attached logs: http://www.mediafire.com/?8thg9ey7kd26882 sip client ip 192.168.1.202 freeswitch ip 192.168.1.35 mrcp connector/speech server ip 192.168.1.32 i have attached 3 logs - freeswitch log file, wireshark on freeswitch server, wireshark on mrcp connector/speech server. my script simply plays back audio from wave [basic freeswitch function], then plays back audio from TTS [which cannot be heard]

Thank you, Michel.

Yes, I get the Audio from FS in regular calls - I already disabled all possible firewalls - all 3 machines [softphone, freeswitch, Speech Server (and mrcp connector) ] are on a switch. 192.168.5.107 is the freeswitch server 192.168.5.110 is the MRCP-Connector/Speech Server 2007 server I made too many iterations on the configuration below:

Show me the MRCP profile configuration and your FreeSWITCH logs during the call.

Hello All, I have MS OCS Speech Server 2007 [working correctly, as i can make SIP calls and use its ASR and TTS Services successfully] I am also using MRCP Connector from AumTech - which allows me to use ASR and TTS Services through an MRCP Client . Now, i am using Freeswitch mod unimrcp to use ASR and TTS.

for TTS, I can successfully make the call, the Audio RTP of the TTS voice is transferred succesfully from Speech Server [through MRCP Connector] back to the Freeswitch Server. However, Freeswitch is not sending back the Audio RTP to the SIP client.

for ASR, I can successfully define the grammar and start recognition, but the audio RTP sent to speech server [through MRCP Connector] is silent [empty].

I am suspecting something is wrong with the RTP Configuration - can you help me?

Let me now if you need any specific logs/scripts/configuration?

Thank you, Michel.
