Re: [asterisk-users] Voicemail- Recorded Mesage Low Volume
Hi Daniel, I'm intrigued by this and wanted to try it out - but I'm wondering how you get Asterisk to call sox at all during Voicemail()? Our server doesn't even have sox installed, so I'm not sure how to go about tricking Asterisk into running a different one. To do anything useful you would have to get sox installed on your server. But to get asterisk to run a different/fake sox, just install whatever you want to run as /usr/local/bin/sox and then edit your safe_asterisk script as I mentioned below. Asterisk runs the program 'sox' using the first match in your $PATH, so by updating the $PATH before asterisk runs you can direct it to run a different sox program. Be aware that this could pose a security issue as some systems allow regular users to modify /usr/local/bin. So people could install other programs that asterisk runs into that directory as well to get elevated privileges. For me it is not a concern as the machine is used only for Asterisk and only accessed by our IT department.

I think this is a bad approach. It's going to be a big gotcha down the road for somebody :) Agreed. :) It would be nice if there was something similar to externnotify that was not just a notification but a pipe that you could modify/filter etc the audio file before it continues on its merry way. Asterisk runs the program 'sox' using the first match in your $PATH, so by updating the $PATH before asterisk runs you can direct it to run a different sox program. A quick grep through the Asterisk (1.2.28) sources shows res_monitor using soxmix if the channel variable MONITOR_EXEC is not defined -- but nothing in app_voicemail. Am I missing something? It is possible this is a 1.4.x feature, and specifically it is for the e-mail sending system which as I am thinking about it is a 1.4 feature. I don't use 1.2.x and never have, I started with 1.4. The other option, again I don't know if this is available in 1.2, is to use the externnotify option. When a voicemail is left this script/ program is called with the context, extension and number of new voicemail messages. With a little bit of shell scripting you could walk the list of all messages and process any left (modified) within the last 20 seconds via sox. It is a little more iffy and prone to race conditions, but it should work. Unfortunately I couldn't give you a specific example of doing it this way as I use the e-mail style.
