Something's not right here. In 75ms light has just made it from here to the other side of the world. Even a PSTN network will provide a longer delay than that calling across the world. And the time to get a response back will be around twice that, which is well beyond that tolerated range. If you're saying there is a limit to the round-trip-time then within the fax specification is a predefined maximum physical distance you can send faxes. Faxing across the world does work so there is something else going here... -- Martijn van Oosterhout Ecomtel Pty Ltd _______________________________________________ Asterisk-Users mailing list [email protected] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
