So, my final configuration is:
One domain with AWS Route53 same weight configuration: 50% server1 and
50% server2
The user register over the domain.
Two Kamailio Servers with DMQ and DMQ_USRLOC modules configured; 1.2.3.4
first server IP and 5.6.7.8 second server IP
Most important configurations *Server1*:
/*listen=udp:1.2.3.4:5060
listen=udp:1.2.3.4:5222*/
/*# ---- dmq params ----
modparam("dmq", "server_address", "sip:1.2.3.4")
modparam("dmq", "notification_address", "sip:5.6.7.8")
modparam("dmq", "multi_notify", 0)
modparam("dmq", "num_workers", 4)
modparam("dmq", "ping_interval", 30)
# ---- dmq_usrloc params ----
modparam("dmq_usrloc", "enable", 1)
modparam("dmq_usrloc", "sync", 1)
modparam("dmq_usrloc", "batch_size", 10)
modparam("dmq_usrloc", "batch_usleep", 1000)
modparam("dmq_usrloc", "batch_msg_size", 60000)
modparam("dmq_usrloc", "batch_msg_contacts", 50)
modparam("dmq_usrloc", "usrloc_domain", "location")
modparam("dmq_usrloc", "replicate_socket_info", 0)
modparam("dmq_usrloc", "usrloc_delete", 1)*/
before the block begin with:
/*$avp(oexten) = $rU;
if (!lookup("location")) {*/
I put
/*if (!dmq_is_from_node()) {*//*
*//*if(reg_fetch_contacts("location", "$ru", "contacto")) {*//*
*//*if($(ulc(contacto=>socket))) == 0 {*//*
*//*rewritehost("5.6.7.8");*//*
*//* }*//*
*//* route(RELAY);*//*
*//* }*//*
*//* }*/
If the socket value is null (0) means the user is registered on the
second Kamailio so send INVITE to second Kamailio
/*route[AUTH] {*//*
*//*#!ifdef WITH_AUTH*//*
*//*
*//*if (dmq_is_from_node()) {*//*
*//* $ru = $tu;*//*
*//*return;*//*
*//*}*/
If INVITE comes from other DMQ node don't need authentication but I have
to change RURI with To URI because I work in a multidomain setting and
I'm using the does_uri_exist function to know if the request is local
or not.
*Server2*:
/*listen=udp:5.6.7.8:5060
listen=udp:5.6.7.8:5222*/
/**/
/*# ---- dmq params ----
modparam("dmq", "server_address", "sip:5.6.7.8")
modparam("dmq", "notification_address", "sip:1.2.3.4")
modparam("dmq", "multi_notify", 0)
modparam("dmq", "num_workers", 4)
modparam("dmq", "ping_interval", 30)
# ---- dmq_usrloc params ----
modparam("dmq_usrloc", "enable", 1)
modparam("dmq_usrloc", "sync", 1)
modparam("dmq_usrloc", "batch_size", 10)
modparam("dmq_usrloc", "batch_usleep", 1000)
modparam("dmq_usrloc", "batch_msg_size", 60000)
modparam("dmq_usrloc", "batch_msg_contacts", 50)
modparam("dmq_usrloc", "usrloc_domain", "location")
modparam("dmq_usrloc", "replicate_socket_info", 0)
modparam("dmq_usrloc", "usrloc_delete", 1)*/
before the block begin with:
/*$avp(oexten) = $rU;
if (!lookup("location")) {*/
/**/
/*if (!dmq_is_from_node()) {*//*
*//* if(reg_fetch_contacts("location", "$ru",
"contacto")) {*//*
*//* if($(ulc(contacto=>socket))) == 0 {*//*
*//* rewritehost("1.2.3.4");*//*
*//* }*//*
*//* route(RELAY);*//*
*//* }*//*
*//* }*/
If the socket value is null (0) means the user is registered on the
first Kamailio so send INVITE to first Kamailio
/*route[AUTH] {
#!ifdef WITH_AUTH
if (dmq_is_from_node()) {
$ru = $tu;
return;
}*/
If INVITE comes from other DMQ node don't need authentication but I have
to change RURI with To URI because I work in a multidomain setting and
I'm using the does_uri_exist function to know if the request is local
or not.
LIMITATIONS:
* works only with a device for user. If a user registered from two o
more devices I don't know how achieve the same behavior
* works with Two Kamailio due to rewritehost function...
* maybe the routing can be better

<p style="margin-left:106.2pt"><span

I'd like to achieve:</span><o:p></o:p></p>
<p style="margin-left:106.2pt"><span
style="font-size:10.0pt">I have two Kamailio using DMQ
and DMQ_USRLOC modules so each REGISTER is replicate on
each Kamailio. I'm using DNS weight to distribute the
REGISTERs between the 2 Kamailios.</span><o:p></o:p></p>
<p style="margin-left:106.2pt"><span
style="font-size:10.0pt">The only difference I have seen
in the location data, with
<b>kamctl ul show</b> command, is the Kamailio receives
REGISTER have socket parameter with transport, ip, y
port like udp:1.2.3.4:5060 where 1.2.3.4 is Kamailio
public IP; the other Kamailio have this field \
empty.</span><o:p></o:p></p> <p style="margin-left:106.2pt"><span
style="font-size:10.0pt">When a call arrive to one
Kamailio, querying the Socket field I can known if I
have to send the INVITE locally or forward the INVITE to
second Kamailio.</span><o:p></o:p></p>
<p style="margin-left:106.2pt"><span
style="font-size:10.0pt">I don't know if there is other
way to achieve this goal.
</span><o:p></o:p></p>
<p style="margin-left:106.2pt"><span
style="font-size:10.0pt">I think PATH protocol not apply
here because If I reply the REGISTER to the second
Kamailio adding path header, I don't need \
DMQ_USRLOC.</span><o:p></o:p></p> <p style="margin-left:106.2pt"><span
style="font-size:10.0pt">The idea is to take advantage
of using these DMQ related modules.</span><o:p></o:p></p>
