These things are extracted from the accounting.cdr table, which are
populated up to 30sec after a call.

There's currently no prepared way to do what you want, but there are
tools on the platform to query real-time call infos, e.g. you can do it
manually like this:

root at spce:~# ngcp-sercmd proxy
sercmd 0.2

sercmd> dlg.list

sercmd>


The above output shows a situation where one single call was running,
and with the from_uri or to_uri you could filter your subscriber info.

You can access the same info via XMLRPC, e.g. like this in
/usr/share/perl5/Sipwise/Provisioning/Voip.pm:

my $dispatcher = Sipwise::Provisioning::XMLDispatcher->new;
my @result = $dispatcher->dispatch("proxy-ng", 1, 1, <<EOF);
<?xml version="1.0" ?>
<methodCall>
<methodName>dlg.list</methodName>
<params/>
</methodCall>
EOF
# filter you call in @result here


Hope this helps to get you going,
Andreas
