[asterisk-users] How to invoke a binary file from the dial plan?
Hi everyone. I'm new with Asterisk and I have to create a dial plan that will invoke a binary code. That is, asterisk will execute a program in the same machine. How to do it? Let me explain what I have to do: In the project that I am currently working, there is smartphones, SIP servers and doors/gates to be unlocked remotely. When the user executes an application on his/her phone, it will presents a button to unlock a remote gate or door. By pressing such button, the application will send a SIP INVITE to the SIP server (Asterisk). In this moment, a existing dial plan should call an executable hosted in the current machine. In this case I need to know how to program my extensions.conf to let Asterisk invoke another software to me. The another software is the one responsible for unlocking a gate or door. So, how to codify my extensions.conf in order to make Asterisk invoke another software? Is another better way (idea) to implement my project using Asterisk and SIP? If so, comment, please! Any hint will be very helpful! Best regards.

[asterisk-users] Forward loop protection...
Ia had a server overload today because someone did a call forward to their own extension. To do a call forward I write a key called CFWD with the extensión number and number to dial . The main script tests if the key/value exists and dials the number stored in the database.

Right after you have read the number to call forward to, compare it to the number you are call forwarding from. If it matches, play the user an error message and have them try again. And no matter what you do, the dumb people will come up with more creative ways to tank your phone system. A large amount of my dialplan code is taking into account the stupid things they have done and handling it properly if they do it again. I swear, if you could harness their creativity for good you could solve the world's problems 10 times over.-- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?

Any hint will be very helpful! Look into the System() dialplan application. It will execute a command on the system for you. Be aware that it will execute it as the user your Asterisk instance is running as, so permissions can sometimes be a bit finicky to get correct. I do something similar to pop my gate open. It is using nc to make a connection to the device, but same general idea as what you are doing.-- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?

Re: [asterisk-users] RES: How to invoke a binary file from the dial plan?
Ok. Thanks for the hint. But, what exactly is a System() dialplan application? Is it a kind of command that i can call in dial plan? I will look for System() related to dial plans. From the Asterisk CLI type: core show application System It will print out the syntax for the command. One of the easier dialplan applications. exten = 1234,1,System(echo This is a test /var/log/asterisk/test.txt) That line would use the Linux echo command to place the text This is a test into a file named test.txt located in the /var/log/asterisk directory.-- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?

[asterisk-users] Results of security honeypot experiment - scraping for IP's/credentials ?
The results of a security experiment were published this week, in which an Asterisk PBX was set out in the wild to see who would attack it and how: http://www.telium.ca/?honeypot1 What I find particularly interesting is that people/bots are scraping support websites looking for valid IP's of PBX's, and valid credentials! A good reminder to everyone on this list to not publish the IP of their PBX's, or even account names (in postings) as they will be quickly targeted -- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?

Could this possibly mean that any person who has CF set should never be available as CF Destination. Simple db entry/check can have this done.

A little later, we’re in deep doo-do0 when Sue forwards to Bob. Could this possibly mean that any person who has CF set should never be available as CF Destination. Simple db entry/check can have this done. That just goes to show that the problem can get complex pretty quickly. Using the original example above, it might be that you want to allow the Bob to Fred to Sue forwards, but only stop it if the Sue to Bob link is established, thus creating the loop. I wonder if you could do some kind of recursive check where you follow each forward and if you ever come back around to a number you have already checked you know there is a loop. To reuse the example above, on the creation of the Bob to Fred forward, the database is checked to see if Fred has any forwards. He doesn't, so is at the end of the forwarding chain. Now Fred forwards to Sue. Again, she is at the end of the chain, so it is allowed. When Sue goes to forward to Bob, the check shows that Bob has a forward. Not a problem, but we create a temporary list that has Sue's number in it. Then we check the next stage of forwarding. Bob forwards to Fred. Fred's is checked against our temporary list and doesn't match, so we are still good. Bob's number is now added to the temporary list and we check the forward Fred has in place. Fred forward's to Sue. We check Sue's number against the temporary list and it does exist. Thus we have a loop detected and the forward can now be denied. I am guessing with the recursion involved you might want to do the check outside of Asterisk and pass the result back in. I will also state that I have not had to do this deep checking in the past, so these are just some initial thoughts on how I would start approaching the problem. Of course, this also assumes that Bob, Fred, and Sue are all on the same phone system. If you don't have a shared database to look at, the problem just got harder indeed. Classic Centrex forwarding required that the target party answer or that call forwarding is forced by repeating the attempt. If calls were provisionally forwarded and an attempt was made to complete a call from the forwarding party to the target, it wouldn’t be too challenging to see if the forwarded call ends up at the initiating extension. This would be effective even if there were multiple phone systems involved (if caller ID wasn’t messed with). --Don -- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?

Glad it worked for you. I usually leave the number untouched, but will manipulate the name to suite what I want. I have mulitple call queues, so for instance, for my helpdesk lines, I will do something like transform Name to HD:Name so that the person being called knows that the caller dialed the help desk number rather than their direct number. On people who work multiple queues, it is very handy so they can see at a glance what queue the caller is reaching.-- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?
