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£º

1. UA1 send INVITE to PC

message bady £º

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 £º

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 £º

Ower/Creator ,session id:8700 123456 654321 IN IP4 10.100.1.15

4. PC send 200 OK to UA1

message bady £º

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 !
