Hi Folks: I am trying to restart a hub node (on a Pi3B).  I am seeing the following errors when manually starting asterisk (asterisk -cvvvv): <snip> [Feb 23 15:16:51] WARNING[1112]: app_rpt.c:22240 rpt_master: rpt_thread restarted on node 2200 [Feb 23 15:16:51] WARNING[1141]: chan_dahdi.c:928 dahdi_open: Unable to open '/dev/dahdi/pseudo': No such file or directory [Feb 23 15:16:51] ERROR[1141]: chan_dahdi.c:7906 chandup: Unable to dup channel: No such file or directory rpt:Sorry unable to obtain Rx channel [Feb 23 15:16:53] ERROR[1112]: app_rpt.c:22223 rpt_master: Continual RPT thread restarts, killing Asterisk </snip> I confess that I have recently installed Mirth Connect on the same Pi (this is the first reboot since doing so).... Indeed there is no folder /dev/dahdi. Any ideas how to recover? OT:  If anyone is using Mirth for any HL7 / FHIR stuff, I am very interested in talking to you! ;) Thanks! Ramesh. VA3UV / KN4RSD
