All,

I've put a new asterisk server at another location and can't seem to get
it working. What's the best strategy to debug connections?

I'm doing inbound SIP only and have installed the server in the same way
as I did on my DEV server. Running an nmap on localhost shows the port
listening:

----------
[asterisk]/> nmap -sU localhost

Starting Nmap 4.11 ( http://www.insecure.org/nmap/ ) at 2008-06-19 21:12 CDT
Interesting ports on localhost.localdomain (127.0.0.1):
Not shown: 1476 closed ports
PORT STATE SERVICE
...
5060/udp open|filtered sip
...
----------
[planet]/etc/asterisk> nmap -sU localhost

Starting Nmap 4.11 ( http://www.insecure.org/nmap/ ) at 2008-06-19 20:11 CDT
Interesting ports on localhost.localdomain (127.0.0.1):
Not shown: 1484 closed ports
PORT STATE SERVICE
...
5060/udp open|filtered sip
...
----------

Is there a command-line tool I can run that will attempt a SIP
connection to a SIP server and provide some diagnostics about whether it
could authenticate or even connect?

Most SIP clients have a logging ability.. you can use those.. but
turning on debug on the server is the best mechanism, as its whats going
on there that counts.

sip set debug <options>

And if you want to get really into the lower levels, then tcpdump will
let you capture the packets for offline analysis in wireshark.

Nmaping against locahost wont tell you much other than an app has 5060
open.. it wont tell you if firewalls are blocking things, or if NAT is
an issue.

All,

I did finally get my server up and running. I thought I'd share some
tools I used.

1) use this to see if asterisk is even listening on port 5060 with UDP
