 Hi all:
 
I am trying to setup follow IMS test environment:
                                    |----------------|
                                    |   kamailo      |-----------SIP--------->SIP server (10.100.1.12)
   8700                          |        |           |                                       |                                           7700
    UA1----SIP/RTP----> |        |           |                                       |--------------SIP/RTP---------->UA (10.100.1.51)
    10.100.1.41               |        |           |                                       |
                                    |   RTP proxy |------------RTP------->Media Gateway(10.100.1.15)
                                    |----------------|                                       
                                         PC 10.100.1.10
                                       
SIP signaling:
 1.  UA1 send INVITE  to PC 
         message bady :
                         Ower/Creator ,session id:8700 123456 654321 IN IP4 10.100.1.41
                         session name: A conversation
                         connection  information: IN IP4 10.100.1.41
 2.  PC send INVITE to SIP server
         message bady :
                         Ower/Creator ,session id:8700 123456 654321 IN IP4 10.100.1.41
                          connection  information: IN IP4 10.100.1.10
.............100/183--------------------
3.   SIP server  send  200 OK  to PC
        
         message bady :
                         Ower/Creator ,session id:8700 123456 654321 IN IP4 10.100.1.15                         
                         connection  information: IN IP4 10.100.1.15
4. PC send 200 OK to UA1
        
         message bady :
                         Ower/Creator ,session id:8700 123456 654321 IN IP4 10.100.1.15
                         connection  information: IN IP4 10.100.1.10
 
after ACK,  UA1 and UA2 are in calling, but no any voice
 
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
          
How to set PC (RTP proxy)  transfer RTP data packages  to 10.100.1.15( Media Gateway address) ?
 
 thanks !
