[asterisk-users] Call Termination Provider Madness

[Danny Nicholas]

Two points;  #1 the more ports you have open, the greater your possible
exposure.  #2 AFAIK you should have 4 RTP ports for each line you wish to
use (although you can tweak some parameter to make it 2) so 10000-10100
should actually be 10001-10120.

At this point I only have ~40 extensions, so I took Michel's advise
and set my RTP range to 10000-10100. The default 10000 ports was a bit
more surface area than I want to expose.

 

If you think 100 or 10k RTP ports going to your voice server makes ANY
difference in security, you really need to re-think this and study more. Not
to be a dick or anything, but really, think about it.
