Hello,
I have a very general question which I am hoping someone can shed some light on. I am really wondering if what I am seeing is normal, or if there is misconfigured hardware somewhere.
I have 2 asterisk servers connected over public internet connections. Multiple carriers in the route between the two. I have both servers configured with
[sip.conf]
tos_sip=cs3
tos_voice=ef
I have done some tcpdump captures and am seeing both asterisk servers sending the IP packets with the approriate DSCP tag. I am also seeing the receiving end with either the QoS headers removed OR modified to a different value.
Is this normal when traversing the public internet? I haven’t done a lot of tcpdumps like this, so I don’t have much to compare to.
thanks.
