I can see the point you're making here, but what's going to
do this after 30 <br>
*minutes* of normal call?<br>

<div>Have seen plenty of ALGs do weird things like this. 30
minutes is a nice number, and nice enough that I'd go
hunting for ALG issues. It's a good multiple of 3 minutes,
and quite possibly is some big number someone thought to set
in something that "no one would ever hit".</div>

<div>A tcpdump would probably show you what's going on if the
logs are otherwise unclear, and you could also make sure you
have sensible RTP timeout rules.</div>
