Which Asterisk cheat script are you referring to?
Does your system provide user access through a website interface inputting data into forms, or are you logging into the server and writing actual Asterisk code?
I'm assuming that this PBX probably runs on some form of Linux, so here are some things you can try:
1. Determine the server's IP address by using the ifconfig shell command.
2. Using an SSH client, you should be able to SSH into the system using
[email protected]. You can use Putty on Windows, or just the regular old Terminal app on Mac OS X. Unless SSH is disabled...
3. Once you are into the system, connect to the Asterisk shell using the command "sudo asterisk -rvvvv" (The V's are for the verbosity level, add or remove them as you please)
4. Once you're in the Asterisk shell, you can run the command "sip show registry" which will tell you whether or not your PBX registered with the far end SIP server at Flowroute. If this isn't happening, something is wrong with your configuration or a password is wrong somewhere. You can also use the help command to retrieve a whole list of all the commands the shell understands. The only ones I ever really need start with "sip."
Check this out.
At the end of the forum post there's some information about using Flowroute, and the specific settings you need.
In addition, if you could post a dump of the Asterisk log, I may be able to pinpoint where the issue is.
