Scott, I've read that manual you linked close to a dozen times. I had all the codecs set to G711uLaw. All my other ATA's are set to the same codec. I gave up and bought two 2-port linksys pap2t ATA's and I had them up and running in less than 5 minutes. Like I said, I could get the first FXS port to both receive calls and dial out just fine. The remaining 3 ports just won't dial out, not for love or money. I'm wondering if maybe the firmware is corrupted or the thing is just on the way out. I just could not find any setting that was port specific (as in a non-global) that had anything to do with outbound routing. The ports would register just fine with asterisk, and like I said, receive calls normally. I like to think I'm pretty savvy with this stuff, but that box made me feel like a first grader trying to operate the space shuttle.
