I know this should be simple, but I unable to find the correct combination. I have a fax line that comes in a FXO port, which is directed to an FXS port which has the analog fax machine connected to it. The inbound works fine. What I am struggling with is outbound, as the requirement is that all calls must go out the FXO port that has the POTS FAX line connected. I also need to remove the need to dial 9 on that line only.
Any configuration examples would be greatly appreciated!!!!
