Hello Nicolas,

so it seems that the method call is still returning a value which Kamailio did 
not properly understand. Two ideas:

- enable debugging in Kamailio to get more information about the warning
- look with e.g. wireshark on the line what is actually returned from mysql

Best regards,

Henning

Re: [SR-Users] high availability and load balancing

[Mojtaba]

Hi,
The concept of HA in IMS is a little different in non-IMS network.
In each node of CSCF in IMS, you could do HA separately.
For example in PCSCF, you could use DNS load balancer to select one of
your PCSCF.  Actually the UE just see one domain as PCSCF, while you
may have more than one PCSCF in your network.
In each PCSCF, you could use dispatcher module to load balance all
Registration traffics between ICSCF nodes.  All initiate traffices
(like Invite message and etc) route to specific SCSCF via
service-route header.
In Registration message in ICSCF nodes, you could use HA to load
balance traffics between SCSCF in LIR Diameter message. For example in
LIA Diameter, you could sent a name of SCSCF thet has lower traffics.
finally the HA in IMS is doning some procedure, not only one or two task.
With Regards. Mojtaba Esfandiari.S

[SR-Users] from Asterisk to Kamailio

[Valter Nogueira]

Today, I use Asterisk as a SIP/RTP PROXY

I proxy from customers Asterisks to a VOIP provider, in a multi-homed
server.

Now, I want to move to Kamailio without any rupture in customer's
configuration.

As anyone can imagine I am kind of lost.

USER ACCOUNTS

In Asterisk, I create a dynamic host account named ACCOUNT1 and I receive
in *FROM HEADER sip:ACCOUNT1@customer_ip_address*

In Kamailio, I have to define the account's domain like *kamctl add
accou...@mydomain.com  password. *Kamailio just
accepts a REGISTER/INVITE from *accou...@mydomain.com
*


SIP/RTP PROXY

In Asterisk, I just dialout to the VOIP PROVIDER like *dial
(SIP/VOIP_ACCOUNT/${EXTENSION})*

Asterisk does all the magic (it is a B2BUA). It bridges the new call and
media to the original call. Moreover, user don't know anything about how
call are completed, nor how credentials are setup and soon.

In Kamailio, I guess that I have to use nat, tm and rtpproxy modules and
maybe uac. I am not sure how to setup it.


Can someone send me a clue?


Thank you,

Valter

Re: [SR-Users] high availability and load balancing

[Kjeld Flarup]

Hi Eyas


A typical HA setup has two kamailio proxies with identical setup.

Use keepalived or similar to give the proxies a shared IP.

Because of the shared IP, all traffic will go to one proxy only.

Thus each of the proxies must be able to handle all traffic, mening the 
functionality must be very simple - no media handling.


Then use the dispatcher module to do load balancing.

Re: [SR-Users] Client Registration and Call over Kamailio

[serkan celik]

Hello,
Olle,

I have tried to add PATH header on Kamailio just before sending Register
request but that did not work. Actually Resgistration became succefull but
when I try to make call IMS sent 403 (Not found  You must register first
with a SCSCF)

Yasin,

I could not get what you suggest? during which phase should I change $rU?.

Re: [SR-Users] Client Registration and Call over Kamailio

[YAS0 CANER]

Hello,

Pcscf adds a path header for s-cscf. So s-csxf can return directly p-cscf.

After saving on p-cscf , u can manipulate r-uri address and then t relay. So 
nothing gonna be changed but r-uri.

$ru =“sip:”+$rU+”pcscf.com:4060”
t_relay()

Did you try it?

You may want to look at using the Path header so that the IMS platform - if it 
supports it - routes calls back through Kamailio. If so, you can forward 
registrations as you do.

I don’t really know much about IMS; so see this as a guess. Kamailio supports 
using the path header.

Re: [SR-Users] Client Registration and Call over Kamailio

[Olle E. Johansson]

You may want to look at using the Path header so that the IMS platform - if it 
supports it - routes calls back through Kamailio. If so, you can forward 
registrations as you do.

I don’t really know much about IMS; so see this as a guess. Kamailio supports 
using the path header.

[SR-Users] Client Registration and Call over Kamailio

[serkan celik]

Hi all,

I am using Kamailio as a proxy in front of a 3rd part Open IMS (Not IMS
modules in kamailio).
I have defined Kamailio as an outbound proxy in Soft clients(I have
configured IMS users info in Soft Clients). When I send register from
client to IMS, Register message is sent to IMS over Kamailio. Kamailio
forwards this received Register to the 3rd party IMS. Finally the client is
registered into IMS over Kamailio. However when I try to make a call from
registered users (both registered over Kamailio), IMS sends 403 Forbidden -
"Not Registered! You must register first with a S-CSCF" to Kamailio.
When I debugged the issue I found the reason why IMS sends 403. When IMS
receives an Invite message from Kamailio it checks whether source IP which
Invite is sent registered or not. As I make registration over Kamailio
without changing contact header, IMS registers the user with the contact IP
(which is the client IP).
So to make a call from Soft client (IMS users) over Kamailio I also need to
register Kamailio source IP as well.To deal with the issue I have changed
the contact address of Register message coming from Soft client with
Kamailio IP  on Kamailio. Then IMS registered Kamailio IP as a contact when
registering IMS user. But this time when I make a call from Soft client
over Kamailio, IMS sends Termination Invite to Kamailio. So to finalize the
call Kamailio has to route this termination Invite to the terminating IMS
user .
Is there any better approach to overcome this issue. Which is the better
approach to use Kamailio in front of IMS. I want to both register and make
a call from Soft clients over Kamailio to the IMS.
