Asterisk doesn't listen to port any port

[rashadmlk]

Listing ss or netstat doesn’t show asterisk on list

sudo nmap -v -sU X.X.X.X -p 5060

The asterisk CLI, doesn’t show any message but tcpdump shows incoming packets fully.

Works for me.

• What does pjsip show transports show?
• Are you running nmap on the same machine?
• If not, from a machine on the same network?
• Are there firewalls involved?

What’s the output of ip a|grep x.x.x.x ?

1. No objects found
2. Yes

4.Yes and allowed as 5060 SIP, udp SIP, tcp SIP

If no objects found, that means transport doesnt loaded successfully?

[rashadmlk]

I think the problem was i put encryption on file via vim. That is why it didn’t load transport. After recreating new file, asterisk started showing packets. To verify i redo same thing but now pjsip module doesn’t load entirely.

No such module ‘res_pjsip.so’
No such module ‘res_pjsip_authenticator_digest.so’
No such module ‘res_pjsip_endpoint_identifier_ip.so’
No such module ‘res_pjsip_mwi.so’
No such module ‘res_pjsip_notify.so’
No such module ‘res_pjsip_outbound_publish.so’
No such module ‘res_pjsip_publish_asterisk.so’
No such module ‘res_pjsip_outbound_registration.so’

Update: Yes , problem was file encryption. And thanks for Pjsip fails, cannot be reloaded - #22 by gjoseph , and this. @gjoseph
