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 !
