It seems on dahdi digital hardware screen isn’t displaying correctly the setting of dahdi hardware configuration.
Just in case if set CAS mode dahdi digital hardware still showing CCS/CRC4.
It seems dahdiconfig module it refers to framing var item, gathering from dahdi_scan result but the strange point it becomes dahdi_scan it report 2 item refering to frame item, framing_opts=CCS,CRC4 framing=CAS.
So question becomes, what’s wrong? dahdiconfig module it refer to framing var where dahdi_scan it report correct value why it displayed framing_opts value?
