Re: [SR-Users] MSRP question

[Daniel-Constantin Mierla]

If the config file is too big, then it is not easy to analyze anyhow.

Can you try to run with debug=3 in conifiguration file, then generate
some msrp traffic to see if you can spot some hints of what happens from
syslog messages?

Cheers,
Daniel

Re: [SR-Users] Stateful Outbound Proxy...

[Daniel-Constantin Mierla]

Hello,

yes -- if you use t_relay() to send out the SIP requests, then kamailio
acts as a stateful proxy.

If you use record_route() and loose_route() in kamailio.cfg (the default
kamailio.cfg uses them, so you can look at it if you started something
from scratch), then requests within dialog end to proper asterisk.

Cheers,
Daniel

I guess nobody from dev team needed transaction operations for sqlite, I
expect that most of us use a larger sql server (mysql, postgres) if they
have presence services...

Your contribution to add them will be very welcome, of course!

Re: [SR-Users] stateful messages in a dialog

Hello,

transaction stateful relaying is done by using t_relay().

For handling them with dialog, use dlg_manage() for those requests.

Re: [SR-Users] How can I send 404 to the caller instead of BYE?

[Daniel-Constantin Mierla]

Hello,

not sure I understand properly, but it seems you want to send a response
(404) to caller, but the caller hasn't sent any request. Even you would
be able to do that, is useless, the caller won't do anything with it.

Again, might be my misunderstanding, so re-phrase if you meant something
else.

Daniel

Re: [SR-Users] HOW send 4XX to the caller when the callee response to bye is 481 Call leg/transaction does not exist

[Daniel-Constantin Mierla]

Hello,

the 481 is sent by the caller, meaning it doesn't know the call anymore.

To help troubleshooting, you have to send the full sip trace of the
call, from initial invite to the bye, including the responses, taken on
sip server, in both directions.

You can use ngrep, like:

ngrep -d any -qt -W byline "sip" port 5060

Daniel

Re: [SR-Users] Framework/Lib to create SIP packets

[Daniel-Constantin Mierla]

Hello,

to add a bit more to the suggestions offered by the others ... if you
have the sip packet in a file, you can send it over with protoshoot
(included in kamailio at utils/protoshoot/).

Maybe more useful will be sipsak, it allows to do a lot of sip stuff
from command line -- this should be packaged on most linux distros, if
not, it is hosted on github by the author Nils Olhmeier:

  * https://github.com/nils-ohlmeier/sipsak

If you need to send over websocket, a while ago I wrote a small tool in
go - wsctl:

  * https://github.com/miconda/wsctl

Daniel

I want to use Kamailio to load balance traffic across multiple asterisks.The 
problem is that my SIP traffic is related to conference, so if a SIP callfor a

[SR-Users] Acc INVITE dialog start timing difference

[Dirk Teurlings - Signet B.V.]

Hi,

I'm seeing a difference in timestamp for acc modules recorderd INVITES
and the dialog start event.


This is the log entry:
Apr  1 12:55:59 host /usr/sbin/kamailio[15642]: INFO: 

[SR-Users] Make Kamailio Great Again!

[Alex Balashov]

For immediate release:

ATLANTA, GA (1 April 2016)--Alex J. Balashov, a self-styled
businessman based in Atlanta, Georgia, USA, has a plan to "Make
Kamailio Great Again".

"Evariste Systems is huge. My name is on the building," said
Balashov of his iconic VoIP consulting brand.

"And you know what, I have been very successful. Everybody loves me."

Balashov has capitalised on a contentious election cycle marked by
deep political polarisation, growing income inequality and geopolitical
challenges such as global terrorism. And his sharp message of alarm
about the declining influence of the Kamailio SIP server project has
resonated with increasing numbers in the CxO suite, vaulting him to
the lead in the race for the IETF SIP Working Group nomination,
according to recent polls of primary voters.

He has been quick to tout his competitive credentials in a tough
global open-source ecosystem. At a recent colloqium on unified
communications, he asked:

"When was the last time anybody saw us beating, let's say, OpenSIPS
in Git commits? They kill us. I beat OpenSIPS all the time. All the
time."

As Balashov sees it, a major cause of the beleaguered Kamailio
project's woes lies in its liberal patch acceptance policy and
lax scrutiny of third-party contributions:

"When GitHub sends its people, they're not sending their best.
They're not sending you. They're not sending you. They're sending
people that have lots of problems, and they're bringing those
problems. They're bringing drugs. They're bringing crime. They're
rapists. And some, I assume, are good people."

He has proposed a controversial solution that has drawn ire from
liberal ranks in the open-source community, but has also attracted
applause and standing ovations at his speaking engagements:

"We have to have a firewall around the Kamailio source code. We
have to have an access control list. And in that firewall, we're
going to have a big fat door where commits and pull requests can
come into the master branch, but they have to come in legally.
The firewall will go up, and GitHub will start behaving."

Balashov's firewall proposal has been met with scorn from critics who
deride it as impractical and quixotic. In particular, commentators
have raised questions about funding and resources as well as GitHub's
willingness to entertain a boundary around a project in its vicinity.
Balashov isn't concerned, however:

"I will build a great firewall--and nobody builds firewalls better
than me, believe me--and I'll build them very inexpensively. I will
build a great, great stateful packet inspection wall on our border
with GitHub, and I will make GitHub pay for that wall. Mark my words."

He has also been rebuked by rival IETF leadership candidates for his
often acerbic Twitter remarks directed at Lennart Poettering and the
developers of "firewalld". As he sees it, however, the network effects
of social media are a strength:  "My Twitter has become so powerful
that I can actually make my enemies tell the truth." He scoffed at
the suggestion that his characterisations of industry actors behind
the RedHat-led "systemd" movement are misleading:

"RedHat was the worst Steward of Linux in the history of the kernel.
There has never been a Steward so bad as RedHat. The source code
blew up around us. We lost everything, including all synergies.
There wasn't one good thing that came out of that administration or
them being Stewards of Linux."

Balashov's idiosyncratic campaign is not standing still. He has proven
to be a capable populist, adapting rapidly to an evolving sense of the
kinds of pronouncements that activate his swelling crowds of devotees.
Along the way, he has deftly deflected calls to subject his policy
proposals to expert review.

"I know what I'm doing, and I listen to a lot of people, I talk to
a lot of people, and at the appropriate time I'll tell you who
the people are. But I speak to a lot of people, but my primary
consultant is myself, and I have a good instinct for this stuff."

At a recent gathering of SIP stack interoperability specialists,
Balashov the latest pillar of his platform to "Make Kamailio Great
Again", in view of growing security vulnerabilities in the latest
Kamailio modules:

"Alex J. Balashov is calling for a total and complete shutdown of
commits entering the master branch from the territory of the European
Union until our project's representatives can figure out what's going
on. According to Netcraft, among others, there are a lot of buffer
overflows in Kamailio by large segments of the EU population."

Re: [SR-Users] Load balancing traffic based on SIP URI

[Alberto Sagredo]

I have done something similar as follows


if($rU=~"^[0-3][0-9][0-9]$")
{
$var(valor)=1;
}

And later..

if(!ds_select_domain("$var(valor)", "4")) {
sl_send_reply("500", "Service Unavailable");
xlog("L_INFO","[$fU@$si:$sp]{$rm} Sin destinos disponibles
para $rd \n");

exit;
}

That could be one idea to do that...

On your load balance table you have to use 0 -> All

1 -> Destination 1

2 -> Destination 2

an so.

[SR-Users] pseudo variables in strings

[Juha Heinanen]

If I have a string that contains pseudo variables, e.g,,

$var(uri_pattern) = "sip:$f...@tutpro.com";

is it somehow possible to replace them with their values, something like:

$var(uri) = eval("$var(uri_pattern)");

Re: [SR-Users] pseudo variables in strings

[Alex Balashov]

‎Juha,

Yes, either by separating the PV elements, e.g.

$var(x) = $fU + "abc";

... or with the newer $_s() PV created for this purpose:

$var(x) = $_s($fUabc);

[SR-Users] about xml rpc response behavior

[Yasin CANER]

  
  
Hello;
      Xml rpc is useful module for kamailio that improve flexibility
  and can help to addons. But there is a little problem about it
  when use non-value response that reply  empty xml or no response
  so there isnt ack about what happened after command sends. at
  least need a "OK" for acknowledgement. i can accept that there is
  a fault reply and it is useful with return code and description.
  after looking http://xmlrpc.scripting.com/spec.html webpage ,
  there isnt any spec about "OK" . if you ask where it uses; For
  example , after module reloads or terminating dialog which callid.
  I think it is good when realtime reload in Kamailio Version 5 can
  be reload by remotly. it can reply which module reloaded correctly
  , which doesnt.What do you think about it?
  
  Thanks

Re: [SR-Users] Load balancing traffic based on SIP URI

[Federico Cabiddu]

Hi,
if I understand correctly your problem is that the first INVITE for a
specific URI will go to a server and the conference will be instantiated
there. Then you must route all the INVITEs from the other participants to
the same server, is it right?
If this is the case why not use algorithm 3 in ds_select_ds (or
ds_select_domain) which does hashing over Request-URI?
(
http://www.kamailio.org/docs/modules/devel/modules/dispatcher.html#dispatcher.f.ds_select_dst
)

Federico

Re: [SR-Users] Load balancing traffic based on SIP URI

[Alberto Sagredo]

Hi Federico. In mi case i have to force some RURIs to a determinate
Asterisk . There was some logic to do that instead letting kamailio to
handle that situations

I haven't tested option 3 , but it must do what you expect i think. Maybe
you would need to adjust
 ds_hash_expire

[SR-Users] Kamailio as a presence server

[Igor Olhovskiy]

Hi!
I want to create custom Presence server. Main idea - phones subscribes to
it (for ex, extension 100@domain). This subscription actually lit BLF
button on a phone.
But main idea - change status of BLF can arrive from different locations
via PUBLISH, I assume.
Problem - phones has different type of SUBSCRIBE, like
dialog(application/dialog-info+xml) or presence(application/pidf+xml). Some
of phones are not fully follow RFC (Like using in SUBSCRIBE R-URI not
domain, but IP, but in From or To - domains are used)
Phones are registered elsewhere, not on Kamailio. After reading RFC
(especially event:dialog part) I’ve found about SIP-If-Match part, but
problem about sync this data across multiple PUBLISH locations.
Can be Kamailio be a presence server in this scenario?

For ex, SUBSCRIBE

SUBSCRIBE sip:212.232.26.232:5060;transport=udp SIP/2.0

[SR-Users] KAMAILIO tcp_send query, connection problem

[Ed Todd]

KAMAILIO tcp_send query, connection problem
I have a KAMAILIO SIP server on a static IP from Comcast, using a modem/router 
Cisco DPC39412B.

I have a PC application server which is successfully signing on to the SIP 
server, via a LAN cable on the same network as the SIP server (Cisco). 

In my second test, the PC application server is connected to the internet via a 
ZTE Falcon Z-917. In a third test, the PC application server is connected to 
the internet via a Talk-Talk fiber broadband. The connection does not occur.

[SR-Users] Multiple Registrations - Overwrite oldest contact

[Bruno Emer]

Hello all.

I have problem here and I tried to find a solution and search over
internet, but without success.

My scenario is the following: I have an application that must be registered
in Kamailio when a user logs in the web interface, so he can get calls
(something like a web softphone using webrtc). At this point, we are OK,
and everything is working fine.

To get these register functions I am using the parameter "save("location",
"0x04")" as described in the REGISTRAR module documentation, so if a user
logs in another web browser or computer, only the last one will continue
registered and all calls will be forwarded to him.

The point is that now we are creating a phone app that will do almost the
same thing as the web interface, allowing users to receive calls using the
mobile device, and here is my problem: I want to allow my users to be
registered on two devices at the same time, but if a user logs into another
device, I don't want to reply with a 503. I want to allow the user to
register again, deregistering the oldest contact.

I saw that there is a module named "ims_usrloc_scscf" and on its
description it says "implemented overwrite oldest contact behaviour", but I
couldn't find any documentation about it.

So, is there a way to get this working today?

There is a modparam to register the amount of contacts per AOR - which would do 
what you need.

Hello, *Olle!*

(actually I wasn't even expecting to get an answer today).*


*I know the max_contacts parameter. But the problem is that if I set the
max_contacts to 2, when the user tries to register again, he gets an error
message 503. The point is that I want to get the user registered, and
replace the oldest location entry for the newest one.*

THen you need to check the parameters to the save() command on the same 
documentation page:
"
0x04 - store and maintain one contact per AoR. If there are other contact 
addresses for AoR not matching current registration, remove them. This mode 
ensures one contact per AoR (user).

Re: [SR-Users] Multiple Registrations - Overwrite oldest contact

[Bruno Emer]

This is my problem... I want to have 2 contacts for AOR, and not only one.

When the 3rd arrives, it must remove the oldest and continue with 2...

*If I am using the 0x04 parameter, it will save just one contact, and the
user will not be able to get the Invite both, in the mobile device and web
interface.*

Re: [SR-Users] Multiple Registrations - Overwrite oldest contact

[Olle E. Johansson]

That requires a bit more of reading the same doc page, but I still think you 
can do it.

Run reg_fetch_contacts and check how many you have. Loop through them and 
unregister by the ruri (id) of the one that expires first
if you have too many.

We’ve made this function to make the location database handling very 
transparent to the script writer that wants to go beyond 
the ordinary and do some fun scripting :-)

http://kamailio.org/docs/modules/devel/modules/registrar.html#registrar.f.reg_fetch_contacts
http://kamailio.org/docs/modules/devel/modules/registrar.html#registrar.f.unregister

Kamailio is cool, isn’t it? :-)

Re: [SR-Users] Multiple Registrations - Overwrite oldest contact

[Bruno Emer]

Sure it is!

This is exactly what I was looking for! Actually I wasn't able to see that
there was a way to perform this action!

Thanks for your help, Olle!

I will try to create this, and when I have it done, I will post my script
here, so if someone else need the same problem I can help.

Now, I have just one more question about my scenario: when I register a
user, is there a way to create something like a "custom field" on the
location? To explain better: If possible, I can add something like a custom
header that says if the user is registered from a phone device or the web
interface, then I can perform the loop and replace only the oldest contact
using that device...

I had filed a bug upstream with Fedora 
https://bugzilla.redhat.com/show_bug.cgi?id=1301301 which eventually helped me 
to find that the Makefile for Kamailio's TLS module is using:

LIBS += $(shell pkg-config libssl --libs)

which only returns '-lssl':

# pkg-config libssl --libs
-lssl

It seems that in order for the version detection to work properly, it also 
needs '-lcrypto'

Perhaps the TLS module Makefile might need to add libcrypto just as the CRYPTO 
module Makefile does:
https://github.com/kamailio/kamailio/blob/master/modules/crypto/Makefile
