Asterisk 16.15.1 with DAHDI 3.1.0 on CentOS7; Amfeltec Piranha USB-FXS adapter.
All works nicely if I start Asterisk as root once the system has booted.
But if I start Asterisk from systemd with “asterisk.service”, I find that DAHDI can’t see my FXS channel until I issue “dahdi restart”, either from Asterisk CLI or using asterix -rx.
Anyone know how to resolve this, or work around, so that the DAHDI FXS channel is automatically available? Had a look on the issue tracker and on web, no joy yet.
Transcript below: pretty sure the warnings are harmless (?).
