Figured out to plug the card and have a running system. Not so.
Elastix hardware detector recognizes the card as "Span # 1: ZTHFC1 "HFC-S PCI A ISDN card 0 ["
but hitting "configuration of span" does nothing.
Futhermore, in System Dashboard, card is "seen" bt "not registered". need the card serial number but have an issure for a missing sql table, cannot "register".
Is there a clean step by step how to have the card up and working as per "elastix certified" ?
great support from Mr. Upper.hua. this has been solved.
to help everyone here are step by step to reproduce it:
login to system tty
tar -zxvf openvox_dahdi-linux-complete-2.8.0+2.8.0.tar.gz
remove this directory:
service dahdi stop
then restart system:
shutdown -r now
