We should not do flood detection on video RTP streams. Video RTP streams are very bursty by nature. They send out a burst of packets to update the video frame then wait for the next video frame update. Really only audio streams can be checked for flooding. The others are either bursty or don't have a set rate. * Added code to selectively disable packet flood detection for video RTP streams.

; Enable strict RTP protection. This will drop RTP packets that do not come

|
; from the recoginized source of the RTP stream. Strict RTP qualifies RTP
|
|
; packet stream sources before accepting them upon initial connection and
|
|
; when the connection is renegotiated (e.g., transfers and direct media).
|
|
; Initial connection and renegotiation starts a learning mode to qualify
|
|
; stream source addresses. Once Asterisk has recognized a stream it will
|
|
; allow other streams to qualify and replace the current stream for 5
|

[ice_host_candidates]
|
|
;
|
|
; When Asterisk is behind a static one-to-one NAT and ICE is in use, ICE will
|
|
; expose the server's internal IP address as one of the host candidates.
|
|
; Although using STUN (see the 'stunaddr' configuration option) will provide a
|
|
; publicly accessible IP, the internal IP will still be sent to the remote
|
|
; peer. To help hide the topology of your internal network, you can override
|
|
; the host candidates that Asterisk will send to the remote peer.
|
|
;
|
|
; IMPORTANT: Only use this functionality when your Asterisk server is behind a
|
|
; one-to-one NAT and you know what you're doing. If you do define anything
|
|
; here, you almost certainly will NOT want to specify 'stunaddr' or 'turnaddr'
|
|
; above.
|
|
;
|
|
; The format for these overrides is:
|
|
;
|
|
; <local address> => <advertised address>
|
|
;
|
|
; The following will replace 192.168.1.10 with 1.2.3.4 during ICE
|
|
; negotiation:
|
|
;
|
|
;192.168.1.10 => 1.2.3.4
|
|
;
|
|
; You can define an override for more than 1 interface if you have a multihomed
|
|
; server. Any local interface that is not matched will be passed through
|
|
; unaltered. Both IPv4 and IPv6 addresses are supported.
