Here’s the deal. I have an ADSL gateway (ZyXEL2600 series) that supports 4 phone lines. It has a dedicated data input and 2 2 line phone inputs. I’m pretty sure its the way this place is wired, but only 3 phone lines work. Had a guy come in ‘n attempt to get the 4th line working but it killed the DSL connection. The way I have it hooked up only 3 lines work and the DSL connection is solid.
I want to find out how to get all 4 lines working along side the DSL. 1 line is shared with the ADSL line btw. So yah, all lines + DSL working would be phenomenal.
