Hi. My set up is as follows: - several voip phones properly registered in 3cx and working on my internal lan - several POTS phones plugged into an analog external US phone service (Fairpoint) I am trying to add a patton smartnode 4112 to the mix so that my voip phones will be able to access an outgoing line. I gave it a static IP on my lan and I can access it's web config page at that ip address. I then added the patton gateway to c3x by clicking 'add gateway' in the c3x config page, specifying the gateway model and following the defaults. In particular I did specify that this was a US installation. The installation appeared to go fine and generated a config file for the gateway that I then uploaded to the gateway via the gateway's config web page. Everything seemed to go fine, and in the c3x config page when I go to VOIP/PSTN gateway I can see what I added. But when I connect the gateway's fxs 0/0 to my external analog telephone line, it suddenly makes all other POTS phones in my house that are directly plugged into the same analog line unusable (very loud interference…so much noise that I am afraid I will wind up hurting the POTS phones). This is true even though I am not using any voip phone to make an outgoing call, so it's strange (I would have thought that until you try to make an outgoing call through the smartnode 4112 that port would simply be open and thus would cause no interference on my analog line). I then went back to the gateway config web page and when I opened up the fxs port entries I saw that (a) the specified country was the patton default of etsi rather than US and (b) the port was disabled. When I tried switching that to US and enabled the port, plugging it in to my external phone line resulted in a pure short (at least I think that's what it was because when it remained plugged in I was no longer able to hear any dial tone when I pick up the other POTS phones). In adding the gateway, I created an outgoing rule to access the gateway if the user dials 9, but I see that that doesn't work either. In case it's relevant, here's the log entry for when I tried to dial 9 (though perhaps this is telling me nothing more than that I don't yet have the fxs port connected properly to the outside line?): After I ran into these problems the first time around, I deleted the gateway from3cx and added it again (and re-uploaded the new config file to the gateway), but that didn't help...same results. Any thoughts? Thanks!
