I upgraded to Asterisk 13.6.0 compiled with pjproject 2.4.5 (dont know if it’s related). I see those messages in the console:
[Dec 6 10:26:33] ERROR: res_hep.c:517 hep_queue_cb: Error 
while sending packet to HEPv3 server: Operation not permitted
I found nearely no informations about this. Someone has an idea of where it may come from, and how to fix it?
Thanks for any help, regards,
