Hello, I have a question about the RTP stream. I made two calls with different devices. One had no problems, the other call made some difficulties. I put an extraction of my traces in attachment. (MGCP device -> Thomson Speedtouch 780WL with a Siemens Euroset 5020 phone) The first one had no problem. When I called the freeSWITCH I had a bidirectional RTP stream. I heard the announcement of the server. I could transmit digits from my telephone to the freeSWITCH which were verified by the machine. (VoATM Device -> Allied Data Copperjet 1616 with a Siemens Euroset 5020 phone) The second call had only a oneway audio stream. When I called the freeSWITCH I heard no announcement of the server which should be actually played. There was only a background noise. I made traces from this example. My suggestion is: In packet 378 the freeSWITCH server wants to sent RTP packets to an suspicious IP. There are over 5 packets in number. Not till then there is the correct destination IP (see packet 386). But this could be the fact that the freeSWITCH produces an error. Does anybody have an idea?
