We recently upgraded a server with dahdi card from CentOS 8 and ASTERISK 18 to Oracle 8.5 and ASTERISK 20. The E1s were up but the LED indicators in the ports of the dahdi cards are all off. After doing a hard reset on the E1 cable (pullout and insert), the PRI status became down and won’t go up. We tried to do dahdi restart, asterisk reload and even reboot of the server but the issue persisted.
Is there any known issue with dahdi cards on Oracle 8? Or do we have to adjust any configuration for dahdi/PRI?
