Sipping_flag must also be set, because matching pings when they
return can be<br>
done only if using SIP pings. Did you set it?<span class="HOEnZb"><font color="#888888"><br>

<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">*Hello
all,<br>
<br>
I’m glad to announce a new feature that allows OpenSIPS
to monitor<br>
(via SIP OPTIONS probing) and disable/delete in realtime the
registrations<br>
which are not responding.<br>
The previous approach had two issues when came to so
called “zombie”<br>
registrations (registrations which are not valid anymore):<br>
* resources - such zombie registrations may waste
resources in your<br>
OpenSIPS server (memory, processing time, DB space, useless
NAT pinging,<br>
TCP connect attempts);<br>
* user experience - using the zombie registration to
reach un-existing<br>
users translates into useless calls (calls that will simply
timeout),<br>
giving delays in the call setup (instead of going straight
to VM, you may<br>
burn 5-10 seconds in trying to reach the user);<br>
The main idea behind these features is to delete
contacts that do not<br>
respond to a certain number of SIP pings. The SIP pinging is
provided by the<br>
nathelper module which was enhanced to keep the state of
each pinging requests<br>
(basically, the module is waiting and checking the reply of
each SIP request<br>
sent to the registered users). For registrations detected as
“dead” (not responding),<br>
the nathelper module interacts directly with the usrloc
module in order to<br>
remove the zombie contact.<br>
For usage perspective, the nathelper module now has two
new parameters:<br>
* ping_threshold - timeout to consider a ping as
unanswered;<br>
* max_pings_lost - the number of unresponded pings after
which the contact is<br>
removed from usrloc;<br>
In order to activate this feature, every contact must
have the sipping_bflag<br>
(to be pinged) and remove_on_timeout_bflag (to be deleted on
no-answer) activated.<br>
This means these flags must also be configured in the
nathelper module. [0]<br>
For full documentation of the nathelper module including
the newly added<br>
feature see [1]. Any feedback is highly appreciated.<br>
<br>
Regards,<br>
Ionut Ionita<br>
