 bb> Thank you Gamgee. That is some great information.

 bb> Where you using an ATA device to hook up your modem?

Yes, a Grandstream HT-802.  I did change a few default settings, that I 
can't actually even remember now, but it wasn't too hard, and the info 
was find-able online.

 bb> So I think I'm having some issues with the ATA or Asterisk, maybe both.

The ATA can be quite finicky and sensitive to mis-configuration.  I 
don't have much knowledge on any of that any more.

Sorry I can't be more help... Hopefully you can figure it out.  Seems 
like it might be a modem initialization string issue.

Good luck!
