I think the 'nc' command you executed was wrong. You have to listen on UDP port 5060.

Quote:
udp 0 0 127.0.0.1:32789 127.0.0.1:5060 ESTABLISHED 11043/nc
Use
Quote:
nc -u -l -p 5060
to listen on UDP port 5060


You are yet to stop the SIP server.

udp 0 0 127.0.0.1:5060 0.0.0.0:* 11008/ser

service iptables check -> stopped
 
is this ok

hi2arun 09-02-2011 08:26 AM
iptables stop is fine.

But did you take care of 'nc' and 'SIP server' as discussed?

maybe ssh redirect might help ??
 
maybe I could use ssh to redirect to eth0

hi2arun 09-02-2011 08:29 AM
Cool. After you got the some message on 'nc' terminal, type something back on 'nc' terminal.

Can you attach packet capture output for this?

gbwien 09-02-2011 08:37 AM
output wireshark trace

Here you can see the message that you typed... so this reached the SIP client.

This means, if you run the SIP server listening on eth0 interface of the Linux instance, things will be fine.

HTH!
