I have he dreaded issue with one way audio till he callis put on hold then off hold. This is for a new set of SBC’s with level 3.
I have a Private connection from level 3. So no Nat.
level3 18.104.22.168 to my ip 10.123.244.169 thats my isp. firewall is off. Ports to L3 open in security group for all nat to here range.
10.123.244.169 to my 10.123.245.18 host. Ports for udp are open in Security groups. No denys in firewalls are found.
my host 10.123.245.18 to my zoiper client.
Call comes, I see the data. I see when I put the call on hold in wireshark I see it does a new invite but the ports stay the same for rtp and now audio. Not sure what I have wrong.
In he rtp data it says I loose a bunch of packets but its the direction I have audio in. so that the only clue I have so far.
