<P>I am trying to setup follow IMS test environment:</P>
<P> |----------------|</P>
<P> | kamailo |-----------SIP--------->SIP server (10.100.1.12)</P>
<P> 8700 | | | | 7700</P>
<P> UA1----SIP/RTP----> | | | |--------------SIP/RTP---------->UA (10.100.1.51)</P>
<P> 10.100.1.41 | | | |</P>
<P> | RTP proxy |------------RTP------->Media Gateway(10.100.1.15)</P>
<P> |----------------| </P>
<P> PC 10.100.1.10</P>
<P> </P>
<P>SIP signaling:</P>
<P> 1. UA1 send INVITE to PC </P>
<P> message bady :</P>
<P> Ower/Creator ,session id:8700 123456 654321 IN IP4 10.100.1.41</P>
<P> session name: A conversation</P>
<P> connection information: IN IP4 10.100.1.41</P>
<P> 2. PC send INVITE to SIP server</P>
<P> message bady :</P>
<P> Ower/Creator ,session id:8700 123456 654321 IN IP4 10.100.1.41</P>
<P> connection information: IN IP4 10.100.1.10</P>
<P>.............100/183--------------------</P>
<P>3. SIP server send 200 OK to PC</P>
<P> </P>
<P> message bady :</P>
<P> Ower/Creator ,session id:8700 123456 654321 IN IP4 10.100.1.15 </P>

<P>4. PC send 200 OK to UA1</P>
<P> </P>
<P> message bady :</P>
<P> Ower/Creator ,session id:8700 123456 654321 IN IP4 10.100.1.15</P>

<P> </P>
<P>after ACK, UA1 and UA2 are in calling, but no any voice</P>
<P> </P>
<P>I found when PC transfer the RTP packages(from UA1) to Media Gateway ,its destination address is 10.100.1.12. and not is 10.100.1.15</P>
