[SR-Users] (Kamailio/RTPproyx) Public -> LAN -> Asterisk (1, 2, .., n)

This is Asterisk LAN IP (just nit changed by me before postin here to
2.2.2.101 for better reading WAN/LAN table).


> Also your Kamailio just sends the c=IN IP4 1.1.1.1 for the very first
incoming call that tells me that RTP proxy function is either running on
1.1.1.1 only or if its in bridging mode then you're not using the right
flag combination to use the 2.2.2.2 IP.

> Is your kamailio set to have "mhomed=yes"; just wanted to know.

I have (thinking yes=1):

mhomed=1

So, Kamailio have WAN interface (in my example 1.1.1.1 public IP), and LAN
- 2.2.2.2.

When I set "IE" on Kamailio in your Echo() test on Asterisk:

if (!(isflagset(FLT_NATS) || isbflagset(FLB_NATB)))
        return;

        rtpproxy_manage("IE");


I have RTP from LAN Kamailio IP - but no sounds:

Sent RTP packet to      2.2.2.2:47274 (type 00, seq 065027, ts 020800, len
000160)
Got  RTP packet from    2.2.2.2:47274 (type 00, seq 008881, ts 020960, len

In "EI" combination - there are no RTP traffic on Asterisk side.
