I am running V11 on a Windows 7 machine. I just put in a new Netgear router (UTM5) and I am setting up the QoS profiles. The router comes with no defined QOS profiles. I noticed that my Aastra phones already mark the RTP and SIP packets with defaults of 46 and 26 for the DSCP service. Wireshark shows the differentiated services field for all SIP and RTP packets originating from the 3CX PBX is zero. Now I don't care about the data between the PBX and the phones. But it seems odd that the phone sends the information to the 3CX PBX and the 3CX PBX remarks it to zero before sending it onto the UTM5 router. I know I can and have remarked them in the router. Wouldn't it be better if the default for 3CX was not to remark them? Or have 3CX mark zero fields to some non-zero industry standard for voip? Is this just a quirk of my system configuration? Did I miss something in the configuration of the 3CX software? Thank you.
