Need Help

Hi List,
Good Day.
I m doing my final year project work.I need to focus on bellow things.

Design Pattern.

For VOIP i have heard lot about Asterisk.I m intrested to know what design patterns are used in code base and possibly any link from where i can find about popular design patterns used in voip/telecom with example

I m sorry if this is not right place to ask .Any pointers or link would be of great help to me.


What do you man by “design pattern”?

In any case, the source code is available, so you can look for yourself.

Details about the internal structure of commercial products is unlikely to be available.
