Hello Steve,
I also couldn’t find a way to pass CRLF with Kamcmd. However if it it an
alternative for you, you can use jsonrpc instead
(https://kamailio.org/docs/modules/5.5.x/modules/jsonrpcs.html). Then you can
use e.g. curl to trigger a registration like
curl --header 'Content-Type: application/json' --data-binary
'{"jsonrpc":"2.0", "method": "tm.t_uac_start",
"params":["REGISTER","sip:test.net","sip:<YOUR_IP>:5060","udp:<YOUR_IP>:5060","From:
sip:[email protected]\r\nTo: sip:[email protected]\r\n"], "id": 1}'
http://<YOUR_IP>:8080/<YOUR_ENPOINT>
Regards,
Markus
