Unauthorized VOIP telephone call - VoIP General, VoIP News, VoIP Providers, VoIP hardware, VoIP software, VoIP Technology

Hello,

I am new in the Asterisk world and have Asterisk after that Tutorial here on my server with public IP installs. Today I stated that somebody telephoned over to my Asterisk server on an Argentine number.

1. Question
How is that possible? Asterisk configured, as in the Howto with sipgate.de.

Here times the excerpt ausm logs:

"", “300”, “00541143494520”, “default”, """ Jean smith "" <300> “, “SIP/51919-08188150”, “SIP/meine SIP ID-0818d968”, “dials”, “SIP/00541143494520@meine SIP ID|30|r”, “2007-04-16 1
9:24: 15 ", “2007-04-16 19:24: 22”, “2007-04-16 19:24: 33”, 18.11, “ANSWERED”, “DOCUMENTATION”

2. Question
How do I teach Asterisk that only telephone calls are possible into Switzerland and to Germany over sowas in the future to prevent? The call has me fortunately only 5 Ct. cost.

Thanks and greeting
TheChief79

Did you in such a way leave also the password as in the Tutorial? I would change that first times…

Greeting,
Yielding pool of broadcasting corporations

Perhaps even an Guest entrance in the same Context as your normal choice rules?

Rear one,

what stands in the default context in extension.conf?

Because which stands in the default context can for everyone make it does not have not at the Asterisk to be announced.

Greetings

Timm

If longer time in requirement takes (e.g. with larger dial plan), you than high-speed solution can change at least times into the Sip.conf in [general] the section the context. (thus instead of default on e.g. an empty context).
The same naturally for Iax (+ [guest] section), or, if iax one does not use, chan_iax2.so in modules.conf deactivate.

But straight on a VServer you should follow Timmbo advice.

Under default in extensions.conf the following stands:

[default]
would Inc.-load => locally
would Inc.-load => echo test
would Inc.-load => mailbox
would Inc.-load => mailbox_own
would Inc.-load => sipgate_out

How have do I to now change, so that it becomes safe? Habs actually as furnished as in does. The password for the terminal (E60) I naturally changed.

Greeting
TheChief

Thus to mine tightness-guessed/advised times the Context “choice rule” as follows assigned and extensions.conf changed:

[default]

[choice rule]
would Inc.-load => locally
would Inc.-load => echo test
would Inc.-load => mailbox
would Inc.-load => mailbox_own
would Inc.-load => sipgate_out

Can I make in such a way? Function does.

Greeting
TheChief

Hello Chief,

oh that means those all this contexte to use from the outside are.
In the detail you would have all include contexte now posts, then more can be said.
What stands in sipgate_out in it?
That looks me so out as if that the dial plan for outgoing discussions is.

Update after your new Posting:

Stands then in the default nothing more?
That is called which you i.d. sip.conf with the Provider context then also context=wahlregel defined?

Greetings

Timm

Actually only with the terminal.

[30]
...
context=wahlregeln
...

Thus the equipment may choice-regulate over the Context rauswrts telephone, if I understand that correctly.

TheChief

Rear Chief,

is correct.
But if a call of Sipgate comes, must be defined also somehow in the dial plan. How looks with you out?
Me became yours Sipgate out interest, because possibly he raustelefoniert over, because that was in the default confessed.

Greetings

Timm

[sipgate_out]
; We use this Context to select from outgoing
; Call numbers over the Sipgate account

exten => _0., 1, dial, SIP/$ {EXTEN} @MeineSipID|30|r

More does not stand there. Are received and outgoing function. Hope with the change can only none more over mine servers telephone.

TheChief

Rear Chief,

exactly that I imagined.
There each call number stands with 0 begins over Sipgate raustelefoniert and in the default context.
There everyone can telephone from the outside over the Sipgate account at your expense.
And stands in a Tutorial, well my gentleman.
Well stands now in another Context, then hated no more problems.
Like for a long time the plant ran already, because until someone finds out which it over your IP telephone can, goes not directly.

Greetings

Timm

How it have to change ichs does that one may telephone only to Germany/Switzerland or other one free of charge countries? Or isn't that so simple?

Greeting
TheChief

Rear Chief,

thus with me looks so out:

For branch 52

[52]
include=default
include=lcr
include=outgoingsipgate.atmeineID

[outgoingsipgate.atmeineID]
exten => _X., 1, dial (sip/$ {EXTEN} @sipgate.atmeineID, 60, T)
exten => _X., 2, Congestion
exten => _X., 102, Busy

With me context only the choice plans for the call numbers stand in the default, then everyone can call me from the outside, as it were by ENUM. e.g.

[default]
exten => 52,1, dial (SIP/52,25, t)
exten => 52,2, Voicemail (su52@default)

So if you want to select only landtechnically then machs nevertheless so:

[lcr]
exten => _0041., 1, goto (outgoingsipcall.chmeineID, $ {EXTEN}, 1)
exten => _0049., 1, goto (outgoingsipgate.atmeineID, $ {EXTEN}, 1)

etc.
By default thus if none applies lcr entry, then it takes:
[outgoingsipgate.atmeineID]
exten => _X., 1, dial (sip/$ {EXTEN} @sipgate.atmeineID, 60, T)
exten => _X., 2, Congestion
exten => _X., 102, Busy

Everything clearly?

Greetings

Timm

Ah, now I am nevertheless surprised. Thus with my local extensions I and in mine context=default extension.conf am the majority of the choice plans for the Raustelefonieren in the default. All different extensions, over which one clean-telephones, to have than context sip in defines.

I can change that now completely easily, by I default umbenene and extensions change my local, but I understood not yet completely, how someone can telephone there over me. I also in no Tutorial found up to now? Can someone explain to me? How can someone telephone over me?

That would be very interesting…

John

Quotation:

Quotation of jobisoft IE can telephone someone over me?

A detailed call without defined goal context (thus ENUM or a call with direct IP selection) lands by by Asterisk default in default.
Without goal context means, if the call e.g. from Sipgate, lands he comes in your Sipgate context and from the fixed net in fixed net.

However no context is responsible, because the call of another source comes goes the call automatically to the context default.

Everything in the context default is possible which, can the caller.

Example:

You meant in your default a rule in it that 00X. to Provider XY to go is, need I actually only the IP address of your Asterisk, then lead I mean international Handygesprche on your calculation.

Explanation:

I select here 00346123456@deine_ip (Spanish mobile phone is a No.)

The call lands on your Asterisk. I am deposited as senders in no context with you, therefore the call goes into the context default.
There Asterisk looks which with 00346123456 to be done is. If there is a rule, he makes also good. It connects me with 00346123456.

Hello,

I set freepbx with asterisk in the most current versions, which are on the market.
How can I stop the “default” in such a way now the fact that is nothing at all possible which costs cause could?
I do not have it completely despite 2mal to read understood…

Rear one uhd,

simply only your internal branches.
Or the things those are internal.
For the branches you context for each MC one, e.g.

[10]
include=default; so that the 10 also the other MC reaches
include=lcr; if you one leases Cost Routing table to have liked
more include=outgoingprovider; so that the 10 also to outside comes

Greetings
Timm

I have 10 iax branches vom191-200
and 10 sip branches of 771-780

those are itself all among themselves maintained internally

and all raustelefonieren only into German festnetz

as that would have to then look dial flat

I am now totally disconcerted whether I the star still run to let am
none on my server comes

man can close not also by asterisk 0900.0700,0137, 0138, and foreign country 00

thanks for your answer

I hope you can me help

Rear one,

Code:

[default]

 exten => 771,1, dial (SIP/771,60, powerplant)
 exten => 771,102, Busy
 exten => 771,2, Hangup

 exten => 191,1, dial (iax2/119,60, powerplant)
 exten => 191,102, Busy
 exten => 191,2, Hangup




 [119]
 include=default
 include=lcr
 include=outgoingprovider


 [771]
 include=default
 include=lcr
 include=outgoingprovider



 [outgoingprovider]
 exten => _X., 1, dial (sip/$ {EXTEN} more @outgoingprovider, 60, powerplant)
 exten => _X., 2, Congestion
 exten => _X., 102, Busy


 [lcr]
 exten => _0660., 1, goto (outgoingA1timmbo, $ {EXTEN}, 1)
 exten => _5553922,1, goto (outgoingsipgate.de, $ {EXTEN}, 1)
 exten => _1959622,1, goto (outgoingsipgate.de, $ {EXTEN}, 1)
 exten => _1959632,1, goto (outgoingsipgate.de, $ {EXTEN}, 1)
 exten => _211000., 1, goto (outgoingTerraSip21100002300, $ {EXTEN}, 1)
 exten => _1955890,1, goto (outgoingsipgate.de, $ {EXTEN}, 1)

So in approximately should look.

Greetings
Timm

Rear Guard x

are right, had I forwards however then forget to set, sorry.

Greetings
Timm

I was now also very much surprised that a course in highest place is and was not adapted after this Thread the examples there. Unfortunately I understood the concept still too little.

Can one reject calls, which are not to be assigned, not simply, instead of letting it run over “default”?

I built a temporary “pseudo protection” in my test scenario now that one can raustelefonieren only over a preselection. Thus should be prevented nevertheless each after far choice outside, or?

How do I configure that better?

It would be very nice, if someone could amend the Besipiel for 1 Provider meaningfully. I read the Thread several times, but understood unfortunately not to 100%.

If you with your internal Usern a line context=irgendwas insert and your context default in something rename become your Asterisk more surely.
Then you put on still another new context default, in make you only one line:

exten => _X., 1, Hangup

Thank you!

To telephone I can test still and must I that from a friend leave.

Quotation:

Quotation of more kombjuder

exten => _X., 1, Hangup

It is a special situation and I would like that the language box of the VOIP Providers is used, if none is configured locally.

A Softphone is not announced, i.e. the PC is out, then receive I now the message that the call is not permitted and the signal for unknown number follows.

How do I reach that registered Softphones, if they are not announced is led to the language box of the Providers?

Edit Guard x: Contributions united, please “changing” function use!
