Help ! 2 X-Lite cannot talk: call failed: 404 not found

Asterisk Asterisk Support
1

Dear All,

I installed an Asterisk on a linux PC, and X-Lite on two Windows

PCs, all in a LAN.

But, when I make phone call from one X-Lite to another, I always get

              Call Failed: 404 not found.


 Here is my sip.conf:

             [Phone1]
             type=friend
             host=dynamic
             ;defaultip=192.168.1.103
             dtmfmode=rfc2833
             context=SIP
             callerid = "Me" <2124>

             [Phone2]
             type=friend
             host=dynamic
             ;defaultip=192.168.1.101
             dtmfmode=rfc2833
             context=SIP
             callerid = "Mini Me" <2123>

        Following is my extensions.conf:
             exten => 2124,1,Dial(SIP/Phone1,20,tr)
             exten => 2123,1,Dial(SIP/Phone2,20,tr)

        Here is the Asterisk Sip debug info:

            Could you help to find out what's my problem?

            Thanks a lot!

Not if you post a great big chunk of debug output like that, no. Nobody’s going to read through that!

The console output with verbose set to 4 would be quite sufficient. But just posting stuff like that doesn’t make many people want to help you. You have to say what documentation you’ve read and what you’ve tried to do to get it to work, for a start.

Hello
I have the same error, my log es

I get the error

[color=green]SIP/2.0 404 Not Found[/color]

My number of softhphone is 1234 and the other is 4321.
In sip.conf I have:

dtmf=rfc2833 or inband

on the other pc

[4321]
type = friend
host=dynamic
context=tutorial

In extension.conf I have

[tutorial]
extent => 1234,1,Dial(SIP,1234)
extent => 4321,1,Dial(SIP,4321)

I have a headache for it…

SIP message 404 means that Asterisk doesn’t believe that the user exists.

In the above cases, I do not see any username= and secret= statements the SIP definitions.

You need to create a username and password to register X-Lite with the server.

Put the username (generally, but not necessarily, the extension) and password in the sip.conf definitions of each extension, and then use them to register your X-Lite software with the server.

You should then be able to place calls between the two X-Lite PC’s.

Hello:

I put the username and secret in sip.conf and I have the same error.
In sip.conf

In extension.conf I have

Did you also setup your softphone to register with the login name and password that you setup in the sip.conf?

When making things work with Asterisk, it’s easiest to think of it as setting up an email system. (Bad analogy, I know, but a client server system is a client server system.) If you don’t login, you can’t use the services.

7

In my asterisk server I look:

CLI> sip show registry
nothing
CLI> sip show subscriptions
nothing
CLI> sip show peers
Name/username Host Dyn Nat ACL Mask Port status
4321/4321 192.168.1.2 D 255.255.255.255 5060 unmonitored
1234/1234 192.168.1.12 D 255.255.255.255 5060 unmonitored

But I have the same error “404 Not found”

The Dial command in your extensions.conf files is mis-constructed.

Change:

extent => 1234,1,Dial(SIP,1234)
extent => 4321,1,Dial(SIP,4321)

To:

exten => 1234,1,Dial(SIP/1234)
exten => 4321,1,Dial(SIP/4321)

Notice that extent is incorrect. It should be exten.

Also, the proper way to address an endpoint, no matter what type it is, station, trunk, line, whatever, is TECHNOLOGY/IDENTIFICATION.

So, proper formats include:

ZAP/1
SIP/201
ZAP/G1

Hope that helps. Don’t be discouraged. Once you learn the basics, it will become easier. No one was born knowing how to configure an Asterisk PBX. (Well, Mark Spencer maybe, but he doesn’t count.)

Thank you

I did the corrections and my pbx is ok
