SIP peer problem

system · January 17, 2012, 5:42pm

Hi
I have a SIP trunk that i should register on server with my public ip address
my asterisk registered successfully on sip server, but i can’t have outgoing call! and the SIP peer is unreachable!
My sip.conf:

[general]
register => my_sip_user:my_sip_passr@server_ip ~400
localnet= server_ip/255.255.255.255
nat=yes
externip=my_public_ip

[mysipuser]
type=peer
dtmfmode=rfc2833
host=server_ip
user=my_sip_user
secret=my_sip_pass
context=incoming
disallow=all
allow=ulaw
qualify=yes
deny=0.0.0.0/0
permit=server_ip/32
insecure=invite,port

with this configuration, i can see my user status in “sip show registry” => Registered
but in “sip show peers” my user status is UNREACHABLE
incoming call are accepted successfully, but i can’t have outgoing call!

localnet should be something like 192.168.1.0/255.255.255.0. It should not be anything to do with the service provider.

Most people do not need nat=yes.

Most people do not need insecure=port.

You don’t seem to have disabled allowguest.

(Edit: Full address with /32 was OK.)

hi
none of these configurations changes the status!
I set allowguest=no but nothing happened
I configure this sip account on my 3CX softphone, it works perfectly! But in my asterisk some thing is wrong but I don’t find it!

david55 · January 18, 2012, 8:05am

allowguest=no improves security. It doesn’t fix NAT problems.

I think you need to provide a clear a diagram of your network and the output resulting when you use sip set debug on.

system · January 18, 2012, 8:30am

My linux connects to internet through a PPPoE connection that gets the public ip address!
The provider provide me a publice ip address as my sip server but i think the real SIP server is behind a firewall!
i enable debug on my peer and get these messages:
SERVER_PUBLIC_IP=> IP address of my provider (i think the ip of provider’s firewall)

There are no REGISTER or INVITE transactions in that trace.

system · January 18, 2012, 9:56pm

My registration doesn’t have any problem! “show sip registry” shows that my account is “Registered”,I have problem with outgoing calls only! “show sip peers” shows peer "UNREACHABLE"
I just get those messages in a loop!!

david55 · January 18, 2012, 10:15pm

The OPTION packets are the result of the qualify option.

You need to have a trace of an INVITE dialogue, and possibly also a REGISTER one, to see which addresses are actually being passed.

system · January 20, 2012, 10:31pm

Hi
I set qualify= no and enable debug on my peer! I find one other public ip address in logs!!
MY_SIP_USER : my sip trunk user name
PUBLIC_IP1: my public ip address
PUBLIC_IP2: public ip address of provider
PUBLIC_IP3: the new ip address I find it i don’t know where is it!!
These are logs of about 10 minutes:

I think you may have the type of ISP that doesn’t want you to run servers, at least not on a cheap account, and deliberately makes changes to the dynamic address.

I asked my provider about your idea, but they said that we don’t have this policy! And they didn’t know about the PUBLIC_IP3!
Also I have a question is there any way to separate asterisk server from soft-phone?! Why 3CX soft-phone works perfectly but asterisk no?!
Is there any difference between packets that soft-phones sends to provider and asterisk packets?!
Is there any solution that for example asterisk acts like a soft phone?
