There may be something else purpose built for this, but you can use<br>
the dialog profiles to track and limit the port usage:<br>
<br>
set_dlg_profile("outcarrier","$avp(out_carrier_id)");<br>
<br>
if ($avp(out_max_call_limit) > 0)<br>
{<br>
set_dlg_profile("profile","$avp(out_qos_profile_id)");<br>
if (get_profile_size("profile","$avp(out_qos_profile_id)","$var(out_gw_count)"))<br>
{<br>
if ($var(out_gw_count)>$avp(out_max_call_limit))<br>
{<br>
xlog("LIMIT: Call $ci - Max call limit hit by<br>
$avp(src_addr) on QosProfile $avp(out_qos_profile_id) to gw<br>
$avp(out_gw_id)\n");<br>
return(-1);<br>
}<br>
}<br>
}<br>
