Re: [SR-Users] tcp_accept_haproxy questions
Hello Grant, Activating it should not affect UDP transport – in fact these different protocols are done from individual Kamailio process (children). About the WebSockets Question – it should work but I am not aware that this was tested so far. Give it a try and please report back to the list.

I assume UDP is unaffected and both proxyprotocol and udp may live side by side? Also, does this play nicely with WebSockets? Taking into account the Websocket connection being setup through a proxy protocol supporting proxy.

Re: [SR-Users] Call limit through shared database
Hello Olli,
you can synchronize dialog profile information between Kamailio servers with
the DMQ replication mechanism. You basically load and configure the DMQ module
and activate it also in the dialog module.
Cheers,
Henning

Subject: [SR-Users] Call limit through shared database
Hello,
I have 2 kam instances using one shared database and both kam servers running
the same routing logic code. Kamailio servers are configured to use the same
database as dialog backend.
I am limiting the concurrent dialogs in the following way but it seems that
kamailio is using its own memory to read profile size rather than the db.
Second kam is not aware of the dialog profiles that the first kam wrote to the
shared db. Is there a way to get multiple kam instances to read profile size
from the same database when calling the get_profile_size function?
modparam("dialog", "profiles_with_value", "concurrent_calls")
modparam("dialog", "dlg_flag", 4)
modparam("dialog", "db_url", DBURL)
modparam("dialog", "db_mode", 1)
route[LIMIT_CALLS] {
if (!dlg_isflagset("1")) { # $td – gateways, $fu - user
if (get_profile_size("concurrent_calls", "$fu", "$avp(calls)")) {
if ($avp(calls) >= 3) {
xlog("L_INFO", "Concurrent calls $fu at limit");
send_reply("503", "Calls limit reached"); exit;
} else {
dlg_manage(); dlg_setflag("1");
set_dlg_profile("concurrent_calls", "$fu");
}
}
}
}
Cheers,
Olli

[SR-Users] BLF 'NOTIFY' not working
Hi
I am using Kamailio 5.2 with the following PRESENCE modules and parameters:
loadmodule "presence.so"
loadmodule "presence_xml.so"
loadmodule "presence_dialoginfo.so"
loadmodule "presence_reginfo.so"
modparam("presence", "db_url", DBURL)
modparam("presence_xml", "db_url", DBURL)
modparam("presence_xml", "force_active", 1)
modparam("presence_xml", "disable_bla", 0)
modparam("presence_xml", "integrated_xcap_server", 1)
I have a Yealink T28P phone which has two lines/extensions successfully
registered with Kamailio 5.2. When I setup the BLF light to monitor one of the
extensions, I get the correct SUBSCRIBE record but the NOTIFY record is sent
over and over again until it fails.

When I register the phone with Freeswitch instead and run the same test, the

Should the message coming from Kamailio contain more data or is that not the
issue. Should I be including other modules also?
All guidance would be appreciated.

Have you tested with a lower value of
https://kamailio.org/docs/modules/5.1.x/modules/dialog.html#dialog.p.update_period
I have it set to 5, but for some reason I'm not using get_profile_size
For inbound:
$var(maxchannels) = 0;
sql_xquery("ca", "select count(id) as c from dialog where xdata like
'%maxchannels%$rU%' and timeout>unix_timestamp()", "ra");
$var(maxchannels)=$xavp(ra=>c);
sql_result_free("ra");
For outbound:
sql_xquery("ca", "select count(id) as c from dialog where xdata like
'%maxchannels%$au%' and timeout>unix_timestamp()", "ra");
$var(maxchannels)=$xavp(ra=>c);
sql_result_free("ra");
Pasting the code here I see this isn't that secure since a user foo also
gets the number of calls for foobar counted against him! Off to put a "
before/after the username.

[SR-Users] Branching 5.3
Hello, if there are no strong opinions against, then it is time to branch 5.3 on git repository. I am considering to do it by the end of the day on Wednesday, October 2, 2019. After that, the master will be again open for new features, while 5.3 branch will continue to get the only fixes and improvements to documentation and tools. 2-3 weeks later we should release v5.3.0, the first stable version in 5.3.x series.
