Hi Alaa, It's pretty easy to code an announcement system using pjsua, and if you don't want to use pjsua you can look at the pjsua code as a guide. Basically when the call connects you create a wav player object and connect it to the incoming call via the bridge. See the --auto-play option in pjsua. You would use --null-audio option so your server doesn't need an audio device to clock media flow. You can use a single conference bridge and use this for all calls. However you will then be limited to using a single processor core which might be a problem if you want to handle hundreds of simultaneous calls. Creating a bridge for each call is more complicated but will allow your server to take full advantage of multiple cores and hence handle more calls.
