Have heard the same, and it is common knowledge on Whirlpool forums
when people have this problem, DSCP is the first culprit.<br>
<br>
I have only seen the complaint about Telstra/Bigpond services
myself, so yes I do believe it may be them implementing it.<br>

<p class="MsoNormal">Something I discovered after an extensive
tshooting. Telstra service on NBN ( TID Service ) actually
drops all non 0 marked DSCP markings. They say it’s actually
NBN doing that, but I do not see this on other providers. I
had phones trying to register across the IPsec through that
NBN, that were failing to do so as long as they were sending
marked packets (phones mark it EF by default ). Once I
remarked the voice traffic to DSCP 0(default), the SIP
registered immediately. Some heavy traffic manipulation or
what? <span style="font-family:Wingdings">J</span> So much
for unhindered transport from A to B.
<o:p></o:p></p>
<p class="MsoNormal">Interesting part was also, even though the
voice traffic is inside the ESP packet, those packets get
dropped, I am guessing due to size+DSCP marking copied to ESP
packet. Anyone seen this before?<o:p></o:p></p>
