No CLI output

Asterisk Asterisk Support
1

I have a new Asterisk server (1.6.2.12) up and running, and configured my sip.conf and extentions.conf for two Polycom phones.
The issue I am having is that I do not see any output in the asterisk console when I try to register these phones. Nothing??
I have verbosity set to 7 and have done a core set debug 99.
I can ping the phones from the server.
I have gone over the configs on the phones and server and can’t see any errors.

I am a newbie to * and trying to learn as I go, any help would be great.

Cheers!
Dave

Sounds like a firewall issue is preventing Asterisk from seeing the requests.

3

The thing is the phones and server are all on the same subnet so a FW should not make a difference.
Or is there a FW built in when I install *?

What command do I type to to make sure my server is running?
When I log in with asterisk -vvvvvvr I don’t see any errors.

Cheers!

asterisk -r only works if the server is running.

You need to provide a SIP protocol trace.

5

Good point - are you even looking at the Asterisk CLI? Try asterisk -vvvvvvc

Here is what I see when I run it as per Batrams:

So this would tell me that * is running, right?

When I connect with asterisk -vvvvvvvr and then reset a phone and try a call I get this output:

No output from the console that the phones are trying to register or failed call or anything?

If you see nothing on the command line when the requests are made then I’d guess that they’re not getting there… maybe you have the wrong IP for the server in the phones or a firewall issue for example?

8

So I rechecked that and still not working.
I have the correct IP for the hosts and server.
Server can ping phones. Phones and server are all plugged in to the same switch sitting on my desk, so I know there is no networking issue. I re-checked the switch and they are all on the same vlan.

Still cannot see the IP phones?

Just for fun, try

to rule out firewall issues

I have never used a Linux FW before, how does this look?

Looks like this may be your issue - you can try flushing all the rules and trying again: http://www.cyberciti.biz/tips/linux-iptables-how-to-flush-all-rules.html

Yeah!
Thanks batrams, that was the ticket.

Cheers!

Remember you were all once as green as I am today…but learning!

Sooooo…

Now I have the one phone registered (AAstra) but still cannot get the Polycom to register?

[root@localhost init.d]# iptables -L -n
Chain INPUT (policy ACCEPT)
target prot opt source destination

Chain FORWARD (policy ACCEPT)
target prot opt source destination

Chain OUTPUT (policy ACCEPT)
target prot opt source destination

localhost*CLI> sip show peers

you may want to use ngrep - it traces the packets before the firewall, so you know what’s reaching your nic:

ngrep -d eth0 port 5060

I don’t seem to have ngrep. How do I install it?

[root@localhost asterisk]# yum install ngrep
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile

??

a bit of googling with ngrep & your distro name should help !

maybe there:
packages.sw.be/ngrep/

its a pretty simple package ! no dependencies
