Got an odd issue. We have an FXS card with our fax number of 0267. When we call the number, it will go to a general greeting. I don't know why the line is being forwarded to the general voice greeting. We haven't messed with any settings on the FXS but we did create a new auto-attendant recording for our general number. However, we were careful not to use any number that was using the 0267 number.
I have attached a doc that shows the setup.
I just realized that you are using an FXO port. Typically these are used to connect POTs lines to your infrastructure. Are you trying to connect an inbound DID from a PRI or SIP trunk and route it to an analog fax machine or something else?
Are you trying to use FXO port to connect the FAX ? if yes you should use FXS to connect the FAX.
If your PSTN FAX lines are terminated on FXO, you need to check the FXO port configuration. Most probably there could be a Plar configuration on FXO port. May be it match your new AA pilot. That could be the reason for getting the greeting.
See the call flow.
Do you have the IOS Gateway configuration that properly for your mgcp Gateway?
I am also curious if you have traced the physical wiring. Do you have a standard analog telephone that you can plug directly into the interface card on the router? If so, do you get dial tone and can you place a call? Can you receive a call directly on the analog phone?
I am not sure where you left those check boxes, but you do need to make sure that all of the forward to voice mail boxes are unchecked.
