My DAHDI phones were broken since a recent power outage (which required a reboot). For some reason the Asterisk or DAHDI configuration is messed up somewhere (probably from an update that was applied before the reboot?).I am using a Digium TDM410 card..
If you were asking if E&M over E1 signalling works on top of R2, ISDN and where can you find a sample Dahdi configuration? Then, no it doesn’t. E&M signalling is the same layer as R2 and ISDN. It is an alternative to them, not anot..
