Hi Everyone,
I am just tweaking a pfSense router and learning lots about NAT etcI
noticed that each call uses four UDP port for RTP. Here is an example of
port for a call I made:
10200
10201

RTP always uses a random even numbered port, then RTCP will use the next
port, which will always be odd numbered. Symmetric RTP only needs two
ports, while asymmetric RTP uses four.

Thanks guys. I am not sure whether that call was asymmetric or not but I saw
4 ports open. It could be that the other two ports were remnant of another
channel even though I doubt it.
Now, when I tried again, it is only 2 ports that is opened like you
mentioned, even RTP port, and RTP port +1.

It may be a sin here, but it is certainly impolite many places,
You really want to read the LONG LONG signature from some people before you
read the actual latest message? I don't know about thatI guess it's a
preference.
Back to my other questions, now that UDP is clear for me, what ports does
SIP require? TCP/UDP 5060 ? and why are there

Thanks. That is in both TCP and UDP for SIP right? or simply UDP would do it
as well? I am talking strictly in case of Asterisk.
Asterisk 1.6 and newer support SIP over TCP. Older versions were UDP only, IIRC.
