check if outbound udp port is accessible


Hi,

I've got a server from which i'm trying to connect on SIP port 5060 to my sip provider through Asterisk. My asterisk settings is 100%, so my question is not related to this.

I'm thinking that port 5060 is either redirected or blocked somewhere between my server and the one i am trying to register to.

How can i check this, i.e some kind of traceroute or telnet or somehting similiar that will work on a port level for udp traffic.

Thanks

nmap will do

Code:
nmap -sU host -p port
