Try to do SIP/IAX2 to: 220.127.116.11
And do a LJ voicepost. (if you have a paid account)
The system is now outside of our network, but is using your LJ pin auth, and we're importing its recordings into LJ's network.
Please report success/failure with method/OS/client/etc.
P.S. It's known to work with iaxComm on Win/Linux/Mac. Username whatever ("guest" or blank), no password. Dial any number (say, "1"), then press "Dial" to connect.
