Hello,
All users are one the same domain, and i use powerdns with mysql backend to
provide DNS DID routing to kamailio.
So, when i need to route a DID to one host, i insert NAPTER entry in mysql,
and on next kamailio DNS request, call will be forwarded to the right
server.
Regards.

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.
Cheers,

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.
