[OpenSIPS-Users] relaying opensips with another sip server

[azza miled]

the two servers are running in separate physical machines. They are
connected via an ethernet network. the ngrep command I'am using is "ngrep
-p -q -W byline host IP_address_of_the_other_server". I don't have any port
mirroring setup. the problem that I don't get that well. The mechanism of
the port mirroring must be installed in the other server, right???
