win2003 sp3
4. UA (phone), gateway or other hardware/software involved:
UA:X-lite
5. Select your network pattern from http://www.brekeke-sip.com/bbs/network/networkpatterns.html :
pattern4
6. Your problem:
the LAN1 network is 134.160.X.X(It's defined as public IP address used in AU),It's behind a NAT,and can't change.The phone 101 calls phone 201, after the connection: The phone 201 can receive the phone 101 RTP packets, but the phone 101 can't receive the phone 201 RTP packets.We used Ethereal,it shows that the packets send to LAN 134.160.x.x ,not public IP address.
Ask how to set in the SIP proxy and in detail.

Thanks

An important attribute of connection-oriented protocols is the setup procedure. One endpoint needs to initiate the connection and the other endpoint needs to accept the connection. The direction attribute is used to describe these roles, and the syntax is as follows:

a=direction:<role>

The <role> is one of the following:

passive: The endpoint will accept an incoming connection.
active: The endpoint will initiate an outgoing connection.
both: The endpoint will both accept an incoming connection and will initiate an outgoing connection.

Hello,

Looks like you fell into the same hole I was in when one of my customers used a lan address that was not in the private address space. Your question practically solved your problem. When this happened to me I didn't realize the lan address was using non private number.

please add the line below into the "sv.properties" file then reboot the server computer.
--------------------------------
net.rtp.follow.remoteaddr = true

I would also upgrade to final release of 2.1 that was released today.

I have changed. LAN1'phone and LAN2'phone talks each other is normal.But the two phone talks(RPT packers communications) within LAN1 will authomatic hand up after keeping a few minutes.
why?

Thanks!
