Asterisk monitoring not working with monit!?

Question

Asterisk

I set up monitoring of the asterisk service and the use of the file system on several hosts.
monit conf contains:
check process asterisk with pidfile /var/run/asterisk/asterisk.pid
start program = "/etc/init.d/asterisk start" with timeout 60 seconds
stop program = "/etc/init.d/asterisk stop "
if failed host 127.0.0.1 port 5060 type udp protocol sip
with target "localhost:5060"
then alert
check host openser_all with address 93.190.240.70
if failed
port 5060 type udp protocol sip
with target "localhost:5060"
then alert
on multiple servers it works. but on one I get an error
[MSK Jun 29 17:28:14] error : 'asterisk' failed protocol test [SIP] at [127.0.0.1]:5060 [UDP/IP] -- SIP error: Server returned status 404
[MSK Jun 29 17:28 :14] error : 'openser_all' failed protocol test [SIP] at [93.190.240.70]:5060 [UDP/IP] -- SIP error: Server returned status 404
and it should be 200 OK
tell me how to fix this

Answer 1

SIP/2.0 404 Not found - the called subscriber was not found, there is no such SIP number SIP/2.0 404
Undefined Reason - undefined direction
SIP/2.0
there is no gateway in this direction, check the routing configuration in this direction.
Which of the 404 errors occurs in your case?
