[asterisk-users] RTP port ranges

[Jonas Kellens]

Hello,

I have defined that I want to receive audio (RTP) on port 11500 till 
11954 (rtp.conf).

The same range I have defined in my firewall.

I now see that an IP-address gets blocked by my firewall because there 
are packets coming onto port 11955.


How come the client sends audio on port 11955 when I clearly define in 
my SDP-body that I want to receive audio on port range 11500 till 11954 ?

What makes the client choose this port number when it is not allowed ?



Kind regards,
Jonas.
