hi all, hope all are doing well!
i am trying to set up analog phones in asterisk 16, with sangoma a400 + fxs modules, but facing some issues to get them up and working.
kindly help me by taking a look at the following errors and please advice on what i am doing wrong? .
now, when i use a multimeter to check the pins of the card, i am getting output from my a400 card, but when i connect my analog phone via 2-pin rj11, the analog phones never come up.
i am also getting following errors during startup:
[VCSS@localhost ~]$ /etc/init.d/dahdi start
Loading DAHDI hardware modules:
using ‘/etc/dahdi/assigned-spans.conf’
Running dahdi_cfg: DAHDI_CHANCONFIG failed on channel 1: Invalid argument (22)
Selected signaling not supported
Possible causes:
FXO signaling is being used on a FXO interface (use a FXS signaling variant)
RBS signaling is being used on a E1 CCS span
Signaling is being assigned to channel 16 of an E1 CAS span
