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.
