[Asterisk-Users] AGI Questions
Hi I'm trying to integrate Arabic numbering in asterisk I've been using agi->stream_file(FILENAME) , but it seems that it doesn't like to send the filename with path Like agi->stream_file(ar/filename) Anyone knows if it is built this way?

One of the great things about PHP is that you can just get one download, compile and install it and it has everything you will probably want for web use built in. No need to mess around downloading lots of CPAN things. Okay there might not be as many libraries available, but for web stuff it keeps life simple. Personally I write in either Perl or PHP depending on the job. Programs I run from the command line are written in Perl and web things in PHP. However I feel both products have things to recommend them. In PHP functions and classes are defined in a more conventional way, none of this pass a stack and pop things off to get your function arguments. Perl feels like it was more carefully thought out. Everything is done in relatively generic and flexible ways. Database support is just fine in PHP but audio would admittedly be less supported.

Familiarize yourself with buffered output. Basically, buffered output is there so the kernel can get a large enough block of data to work with to be efficient when it does the context switch to the app receiving the data. The problem is these buffers are usually around a half k or more in size and not line oriented. You need to flush the buffer through to the other application(AGI) to make sure it gets the whole line to process with the line terminator so AGI knows to start working on the command. the flush command takes care of that for the buffers you are writing to. I'm not too sure about the buffers you will be reading from. > >All of them are passed via the stdin at the beginning, some will vary > >depending on what is available on your channel.

Yes and no. You can set the priority, extension, and context of the dialplan to resume at when you exit. You can even dial out, but at the moment you dial, the AGI app will no longer be in control. > Thanks for any help..

I think calling it Perl lite is justified. It does a lot of what perl does, but without some of the bloat that comes with perl. I write all our web apps in php specifically for the speed in which I can write them, and the speed in which they run. I write non web app applications in perl because of the extended functionality. I think calling it perl lite is less belittling than the comments I hear regularly which is perl--. It has been commented by many people out side of this forum that php tries real hard to not reinvent perl, but they tend to do it that way anyways after a while because it is easier. I don't know if that is true or not. I do see how easy it is to copy php code to perl and barely have to change anything to make it function. This is because perl, for the most part, is a super set of php. As for the helping WipeOut, I thought I was, I answered his questions.

Re: [Asterisk-Users] AGI questions..
Are there corresponding AGI commands for the Asterisk commands?? eg a command to dial instead or using the Asterisk "Dial" command.. Not one-to-one correspondence. Some of the basic ones you need are there. ANSWER AUTOHANGUP CHANNEL STATUS [] EXEC GET DATA [] [] GET VARIABLE HANGUP [] RECEIVE CHAR RECORD FILE [BEEP] SAY DIGITS SAY NUMBER SEND IMAGE SEND TEXT "" SET CALLERID SET CONTEXT SET EXTENSION SET PRIORITY SET VARIABLE STREAM FILE TDD MODE VERBOSE WAIT FOR DIGIT See here: http://www.voip-info.org/tiki-index.php?page=Asterisk+AGI for an overview On that page you'll find a pointer to http://home.cogeco.ca/~camstuff/agi.html which is a good, but a bit out of date, documentation. Here you'll find examples and advice on how to programme in C, Java, perl and python - not PHP, but I think you'll grasp the stuff anyway and is able to adopt it to PHP. One of the commands is EXEC which deliver the power of all your registred applications. I believe that there are samples in the distribution as well as in the Perl library, which you'll have to download from another site (referenced on the Wiki). Even though you won't develop in Perl, those are good examples to read through. I hope this helps. When you're done, I hope that you add some experiences and examples on how to do AGI apps in PHP to the wiki :-) /O ___ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users

I agree that perl is very powerful but our inhouse skills are in PHP.. So if possible I would prefer to do it in PHP..

Re: [Asterisk-Users] AGI questions..
Hi, I'm trying to use the h extension for postprocessing, but for now I couldnt do it, it runs, but lacks debuging output; well, to tell you the thruth, I didnt try to hard to make it work from the "h" extension. What I do is this: the script is for controling prepaid accounts. I do the post-call processing at the beginning of the script (that is, calculate the cost of the pending processing calls and substract the amount to the account, *before* placing a new call). So, the last call is not processed until the user tries to make another one. It works perfectly well in this way, but I think its cleaner to calculate the cost after the user hangs ups. > >Hi, > > > >I use asterisk-perl and when I execute Dial from my script, it stops > >procesing it and I cannot perform cleanups or post call operations in that > >script.
