Hello, I need to limit the RTP ports used by an asterisk in a client, Actualy the range defined is from 10000 to 20000 udp ports. If I only have 10 local sip extension ?how many ports/range should I set up in /etc/asterisk/rtp.conf? Which is the way to calculate the rtp ports needed on an instalation? Thanks in advance, Voipcrazy.
In my installation, netstat usually indicates 4 ports per extension, so my
assumption is that you would need 40 ports or a range of 10000-10039.

Hello,

Actualy the range defined is from 10000 to 20000 udp ports.
If I only have 10 local sip extension ?how many ports/range should I
set up in /etc/asterisk/rtp.conf?
Which is the way to calculate the rtp ports needed on an instalation?
Thanks in advance,

Also take transfers into account, i.e. phones that run more than 1 call in parallel. Philipp
