I have a very strange issue. The problem is that my asterisk server was working perfectly for 1 year but few days ago it started to loose e1 D-channel,
Telco always says that their side is OK, what should i check from below output ? Where should i find some information in order to make a debug and talk to my telco.
i tried to Recompile/reinstall dahdi i even upgrade dahdi-linux-complete from version 2.2 to 2.4 but no avail
Digium TE420 ,asterisk-1.6.1.6,libpri-1.4.10.2,dahdi-linux-complete-2.4.0+2.4.0, Running on Debian Lenny
