Call problem

[rmilone]

1. Brekeke Product Name and version: Brekeke SIP Server 2.2.6.2 Academic

2. Java version:

3. OS type and the version: Win2000 Professional SP4

4. UA (phone), gateway or other hardware/software involved: X-Lite, Cisco 2621

5. Select your network pattern from http://www.brekeke-sip.com/bbs/network/networkpatterns.html :

6. Your problem:

Hi all, i am doing some test on the SIP Server and all working well but one thing. I explain my network schema:
- Brekeke SIP Server with private IP 192.168.40.x and a static nat from Cisco 2621 with public static IP;
- I can registrar telephone (Linksys, Cisco) and softphone (X-Lite) and others from internet (public IP) and from intranet (private IP, from class 10.x.x.x) with no problem.
So, this is the story.
Now, when I call from indise (private) to indise (private) all is working well.
From indise (private) to outside (public) all is working well.
From outside (public) to outside (public) all is working well.
From outside (public) to indise (private) NOT work.
When I try, the remote doesn't ring and my X-Lite rest in "calling..."
The same thing with other phone (Cisco, other UA).
I have noticed on the SIP Server that when I call, the "active session" page show me the call from "my_number@192.168.40.x:port" to "remote@public_IP" and it doesn't work.
When I try outside-outside call, for example, I see "my_number@192.168.40.x:port" to "remote@192.168.40.x:port" and it work well.
I think the problem is there.
Hope make me clear.
Tnx in advance

At that time,what kind of "Status" can you see in the [Active Sessions] page?
Is it "Inviting"? or Is it "Ringing"?

Hi James, thank you for your attention.
The "status" I see is "Inviting" and nothing else.
My UA/phone remain in "calling..." and remote receive nothing.
Any idea?

[james]

Hi,

It seems the SIP Server didn't receive any response from the destination.

While "Inviting" is shown in the [Active Sessions] page, what kind of Destination IP address can you see there?
Is it correct destination address?

Probably I was not clear in my previous post.
When I said that I see "my_number@192.168.40.x:port" (and I was nat behind a public IP address) to "remote@public_IP", this remote UA is a Linksys SPA941 registred to the SIP server with 103@10.0.1.2:5060 because its local with the server.
The "remote@public_IP" that I see is the static public IP address that I have assigned to the SIP Server.

For best comprehension I put the info like apper to me:

< Registrered Clients >

103 sip:103@10.0.1.2:5060 Expires : 3600
Priority : 1000
User Agent : Sipura/SPA941-4.1.8
Requester : 10.0.1.2:5060

(the "remote" Linksys SPA941 for me)


12345 sip:12345@217.133.47.15:10728 Expires : 3600
Priority : 1000
User Agent : X-Lite release 1100l stamp 47546
Requester : 217.133.47.15:10728

(my X-lite phone)

I did not understand how can, the SIP server, address the "To-uri" field with the public static IP that I assigned to instead to address it with the private one the 101 user registered itself (10.0.1.1)....
Hope that its clear now
Tnx you

[james]

Hi

Does your SIP server have two private IP addresses?
One is 192.168.40.x. Another is 10.0.1.x. Is it correct?

What kind of interface IP addresses can you see in the [Server Status] page?

[rmilone]

[james]

Well.. It is getting clear..

You need to set the global side IP address of the router as the interface at setting of the SIP Server.

Hi James,
that is it. Now it works!
Thank you very much indeed for your attention.
See you
