after connecting a phone to the pxs ports, there is no dial tone and i cant dial either. If i dial the box, there is an activity in the box and it is providing me a ring tone after reading the logs. However, i cant hear anything from it.
Im suspecting that there is a problem with the fxs ports.
Again, I cannot say for sure without looking at that unit. I can say that since working with Quintum units from 1999 I think I have only ever seen a FXS port go bad once. I am not saying that is not the problem, but just really have not seen it enough to say. I have seen many FXO ports go bad.
