SIP IP-Trunk to be authenticated based on username and password, not IP address
Hi List; How can one Asterisk Box A to send a SIP call for another Asterisk Box B, and that call to be authorized based on the username and password, and not on the IP (as the IP address of the source is not known because it keep changing)? I think the trick in the Dial command, how to write it properly in a way that other Asterisk Box can recognize the sip username and password which are existed

Does anyone have ever heard of a bug with this function or did I do something wrong? Greeting, Johan Wehrli

[LLVMdev] LLVM instrumentation
Hi everyone, I would like to instrument my code in order to know the number of times a function is called and its execution time. After some research, I find several leads in llvm/lib/ProfilData/ and llvm/lib/Transform/Instrumentation/ but nothing conclusive. Does anyone know if this is already possible with LLVM or has a good suggestion for the beginning? I saw the -fprofile-instr-generate,

Sipura SPA-841 Volume Oscillation Problem
Hi all, The problem is on the volume of the voice sent by the SPA-841. I think the echo cancel algorithm sets a limit to the microphone when detects sounds or noise from the earphone. This problem generates an oscillation on the voice volume sent by the phone and even turns it off completely for very little lapses of time making the communication very uncomfortable. I manage three different

It's a fair point, though I'm not sure how much of that work would be thrown out (some of it would be reusable - since it'll force the front end to track type information wehre it might've previously been relying on the IR types). Reckon it's worthwhile? (I can certainly see that side of it - throwing all this churn in when we don't quite know how it'll play out in the end seem risky, but it seemed like those who're invested in this stuff felt pretty...

Transfer information IR to binary
Hi, I want to know if it is possible to pass information from IR to the final binary (like a constant value)? I have a module pass in IR who make some transformation and, once the compilation is finished, I need to apply a post-processing. The post-processing need information from the IR part.

PHP/AGI Problem
Hi I am currently developing a IVR application using PHP/AGI. I am using the PHPAGI class at http://phpagi.sourceforge.net/ to handle the commuication with my *. The application basically asks a caller to enter in some information which is then processed and a answer is read back out to them. I want the application to loop back to the beginning after giving the answer so they can try another
