I have Issabel installed on a Centos 7 Linux Server.
I configured 2 IAX2 extensions.
But I don't know why I cannot set up an account on my terminal connected to that server.
With a previous installation (almost the same configuration like this) I was able to connect properly, but I don't know why I cannot do it now.
When I run (to check UDP opened ports):
$ sudo nmap -sU -O localhost
I get:
Starting Nmap 6.40 ( http://nmap.org ) at 2017-11-24 05:01 CST
Nmap scan report for localhost (127.0.0.1)
Host is up (0.000057s latency).
Other addresses for localhost (not scanned): 127.0.0.1 127.0.0.1 127.0.0.1
Not shown: 995 closed ports
PORT STATE SERVICE
68/udp open|filtered dhcpc
69/udp open|filtered tftp
5000/udp open|filtered upnp
5060/udp open|filtered sip
5353/udp open|filtered zeroconf
Too many fingerprints match this host to give specific OS details
Network Distance: 0 hops
As you can see, the 5060 port (SIP) is opened but the port: 4569 port (IAX2) is not.
Any idea on how to troubleshoot this?
Thanks!
