One of the tricks I always do with my asterisk systems, once I have pretty much finalized my dialplan is to thin out the unnecessary modules from asterisk. This helps to reduce its memory signature. I did that with my test VICIDIAL system today and thought I would share my modules.conf. Now this is a test system so I am not sure if I miss something that is vital. The asterisk version I am using is 1.2.14.

Here is my modules.conf file:

Does anyone see a modules that I might have missed and could need, or any that I have loaded that are not necessary?

Does everything work?

What kind of trunks do you use?

What kind of memory reduction do you get with this over default?

Every system is different, and some of the things you commented out are needed for functionality on some systems, like codecs for example and callerID modules.

As far as I can tell everything is working. The system is a test dialer that just runs the performance testing loop. This is why I asked if anyone saw something I missed.... It is using IAX to connect the "agents" and to the "phone company" which are actually the same box. As far as memory reduction see for yourself.

These were both taken after a fresh reboot. There are currently no active campaigns either.

I realize that every system is different. Which is why I plan on going a bit more in depth in the process of doing this once I am sure I have all the core required moidules.
