Hello,
I'm using the dialog module to control the maximum number of calls allowed to be
passed through.
Is it possible to share the dialogs stored in memory with multiple instances of kamailio?
So if both kamailio instances process calls, and the maximum is set to a global of 10,
both combined should never let more than 10 calls through.
Regards,
Grant

Hello,
Currently, this is work in progress. But in the meantime, it is possible to
achieve using htable with dmq enabled.
I can post an example later if required.
Cheers,
Charles

Hello,
hmm, I thought there was already a patch from Alex Hermann, might be
just early for me here and that was just in the plans, because he
changed how the profiles are stored to allow mixing from different servers.

Hi Daniel,
Alex's work is still in a personal branch since he ran out of time to
finish, IIRC. I have plans to look at it over the next week or so, unless
Alex has other ideas.
Perhaps he can comment?
Best,
Charles

I couldn't get the dialog+dmq+tm combination in a stable state, it kept
crashing on me. Accounting for packet loss and out-of-order events required
changes to the dialog module which might have caused the issues. Because i ran
out of time i had to abandon that route and went for a quick mod_perl script
to send events to an external counter process.
I still think the concept is ok and i probably need to take another stab at
it, but i have no estimate yet of when that might happen.
If anyone wants to pick up, please do.

Hello Charles,
I’ve looked at the htable and dmq modules, but I don’t understand how to integrate this
with the dialog module.
Could you post an example please?
Thanks!

Hi Grant,
There is no integration with the dialog module directly - that is coming
soon - but for now you can track call profiles across the cluster by doing
something like:
loadmodule "dmq"
loadmodule "htable"
...
modparam("dmq", "server_address", "sip:MY_IP_ADDR:5080") #
<--- make sure
you listen on a separate, restricted port!
modparam("dmq", "notification_address",
"sip:REMOTE_DMQ_ADDR:5080") # <---
we just need to tell DMQ about one other node - it will learn about any
others itself
...
modparam("htable", "enable_dmq", 1)
modparam("htable", "htable",
"call_profiles=>size=7;autoexpire=3600;dmqreplicate=1;")
...
route {
if (method == "KDMQ" && $Rp == 5080) {
dmq_handle_message();
exit;
}
# handle requests within SIP dialogs
route(WITHINDLG);
...
# on INVITE, add the call to one or more "profiles"...
$sht(call_profiles=>$ci) = "external:" + $fu; # you can append more
if required (+ ",international:" + $fu + ",outgoing:" + $fu...)
t_on_failure("FAILURE");
...
}
route[WITHINDLG] {
...
if (is_method("BYE")) {
$sht(call_profiles=>$ci) = $null;
}
...
}
failure_route[FAILURE] {
...
$sht(call_profiles=>$ci) = $null;
...
}
Now, any time you need to, you can get the current count of calls in any
profile for any user by doing...
$var(count_external) = $shtcv(call_profiles=>external:$fu);
$var(count_outgoing) = $shtcv(call_profiles=>outgoing:$fu);
The above offers flexibility of adding calls to multiple profiles, but if
that is beyond your requirements, you could equally just
increment/decrement a counter for each user with:
$shtinc(call_count=>$fu)
$shtdec(call_count=>$fu)
I put this together quickly, so please excuse any typos or omissions, but
it should hopefully be enough for illustration purposes.
Regards,
Charles

Hello,
in 4.2.x should be dialog profile replication on top of dmq, added by
Alex Hermann. I haven't played myself with it yet.
In the past versions, I used various mechanims, like shared database
with queries, notification from config file (park the invite,
uac_req_send() with the local number of dialogs, then wait for response
from the peer to allow the call or not) or relying on htable (which has
alse replication via dmq).
Cheers,
Daniel
