Hi!!
We work with ser 0.8.14, and mediaproxy. As clients we are using two
Windows
Messenger 4.7 in two different ADSL (NATed) lines connecting to SER in
a
public Internet address.
The scenario is as follows:
The sip server is listening on 194.179.25.55. The user
chano@ wmserver.hi.inet on the machine sayuritra (private address:
172.26.0.52, public address: 217.125.212.22) calls to the user
raquel at wmserver.hi.inet on hobbes (private address: 192.168.1.34,
public
addess: 80.32.97.245). The messages captured in the sip server are the
following:
