Hello,
I can't use load balancing feature because location of sip user is
defined.
but then how the DNS is returning the appropriate server? Or each user
has a different domain?
One DID is routed to one server. One to one
relationship.
The probably you can use mtree to associate dids with ip addresses
(or
dispatcher set ids).
So if loadblancer send phone call on one server, but
user is not
registred on this one, call is hangup/lost.
I will use LCR for outgoing call. LCR will "help" CBx to find best
carrier following rules defined by administrators. LCR can probe
gateways ? I have set ping_interval etc but ping is not sent by kamailio.
I don't know if lcr can ping gateways. I know dispatcher does it.

Hello,
dns naptr is ok for locating servers as long as you control the
local infrastructure and make sure dns changes propagation is done
right.
An alternative would be using dispatcher module as a load
balancer. It has a lot of features for this use case, different
distribution algorithms as well as probing the servers (CBx) to
see which one is available.
If the perfomrance is the concern, keeping most of the processing
inside the kamailio is a good choice.
Cheers,
Daniel

Hello Kamailio users,
I'm working on a sip infrastructure, with opensource
technologies, and of course Kamailio will run on my new
infrastructure :)
Kamailio will be my central routing engine, between SBC (running
on asterisk), and somes boxes (asterisk too) where customers will
be registred. Please find below my future infrastructure:
----------
--------------
-------- ----------------
| SBC1 | - - - - - | - - - -| kamailio1 |- - - - - | - - - - - |
CB1 |-----------------| SIPPHONE |
---------- | --------------
| -------- ----------------

| SBC2 | - - - - - | | - - -
- - | CB2 |
---------- |
| --------

---------- | - - - -| kamailio2 |- - - -
-| --------
| SBCn |- - - - - | -------------- | - - - - -
| CBn |
---------- |
| --------
Kamailio high availabality will be done with loopback address and
BGP in two datacenters. SIP carriers will be connected to SBC and
customer to one CB.
I have made some tests with kamailio, and i use LCR to route call
from CB to SBC, using wheigt and prorities to send call to carriers.
Then, when a call arrived from carriers, i use DNS NATPER lookup
to find the right CB box.
CB HA is done using DNS SRV. So user is registred at one
location, and only one. No location sharing beetwen boxes.
I have some question concerning my architecture, and technologies
used to routing call.
Is LCR is the best option for routing call between multiple
carriers ? DNS NAPTER is a modern solution to find an endpoint on
this architecture ? Existing a better way to route call with
kamailio, for exemple rt-json and curl ?
In my point of view, kamailio should be a routing engine, using
internal technologies, to maximise performances. Less work with
kamailio and external app, best performances in sip routing. Is
it the good vision ?
Thanks in advance.
