[Asterisk-Users] Hint: how to include dialplan files from remotesystems

[Alexander Lopez]

Good Idea. I am doing a similar thing but for a different reason:

 I use the system call to bring in mp3 files for music on hold. We make
custom Music on Hold messages and we store them at our DC. I am also
using this to pull mp3 updates for holiday music.

Try doing any of this with any OTHER PBX!!! Betcha can't!!!!
