Cannot connect to SIP account

Asterisk Asterisk Support
1

Hi,
I’ve installed asterisk 10.7.0.1 and configure my sip.conf as :

[general]
transport=udp

[friends_internal](!)
type=friend
host=dynamic
context=from-internal
disallow=all
allow=ulaw

[demo-alice](friends_internal)
secret=verysecretpassword ; 

[demo-bob](friends_internal)
secret=othersecretpassword ;

and extension.conf as :

[from-internal]
exten=>6001,1,Dial(SIP/demo-alice,20)
exten=>6002,1,Dial(SIP/demo-bob,20)

but I cannot connect to any of these SIP account… There is no out put in the asterisk consol nor in the asterisk log message.
Your help will be appreciate.

Check your firewall and angle the sip debug.

3

My serveur is on internet and My provider has assure me there is no firewall blocking SIP traffic.
regards.

4

In that case, provide the SIP debug output.

5 
asterisk -rvvvvvvvvv
sip set debug on

I try to reconnect the softphone nothing appear in the console and in log message file.
regards.

6

In that case nothing is getting to port 5060 on the Asterisk machine. You need to check firewalls (including on the machine itself, routers, and the addresses used).

7 
[root@vps2708-cloud ~]# telnet localhost 5060
Trying 127.0.0.1...
telnet: connect to address 127.0.0.1: Connection refused

it seem that sip port is not reachable even from the server itself.
regards.

SIP is normally UDP.

(It can be used as TCP, but you need to explicitly enable that.)

Hi, I’ve issue nmap on a linux-pc from my network here is the output:

[root@localhost ~]#  nmap -sU -p5060 serveur_ip

Starting Nmap 5.51 ( http://nmap.org ) at 2014-06-06 15:38 GMT
Nmap scan report for vps2708-cloud (serveur_ip)
Host is up (0.61s latency).
PORT     STATE         SERVICE
5060/udp open|filtered sip

Nmap done: 1 IP address (1 host up) scanned in 8.95 seconds

It seem that SIP port is reachable from my network, so why my softphone cannot connect?
regards.

Maybe your ISP block the regular VoIP ports try to change the defaults and try again.

13

And provide the output of:

netstat -punta from your PBX
iptables -nL from your PBX.
And nmap -sU -p5060 yourpublicip from your PC.

Hi,
I still waiting for solution :cry:

I think you have reached the point where you need to hire a local consultant.
