I am using a 1760 router equiped with FXO interfaces as VoIP Gateway connected to 2801 CCME router.
The problem I am having is this: When I plug the line from the DSL splitter to the FXO port, calls from the PSTN don't get trough but you get ringback tone when calling. For testing purposes when I connected the incoming PSTN line that goes to the splitter straight to my FXO port, then PSTN calls come in all right.
To summurize, PSTN calling works without DSL splitter and doesn't with the splitter.
Thanks for helping me in knowing what the problem is and how to solve it!
