Hi,

I wrote it ;-)

You could check a branch with some changes regarding CSeq Handling:
https://github.com/kamailio/kamailio/tree/carstenbock/dialog_cseq_update/src/modules

I use my branch to send frequent in-dialog INFO messages (USSD, 
https://github.com/carstenbock/ussd-poc), which works fine. I haven't found the 
time yet to do more testing, so I haven't done a PR for it yet.

Thanks,
Carsten

Hi All,

However when I issue it again, it sends another REINVITE but with the same CSEQ

How can you ensure its incremented or can you set it somehow?



As would like to generate at least 2 reinvites per dialog.

I haven't implemented this function, so I am not sure if it leverages it, but 
the dialog module has a modparam to enable cseq tracking, which is used by uac 
module for auth functionality. If you haven't set that parameter, try with it 
and see if it does the magic.

Cheers,
Daniel

Re: [SR-Users] topos xavu_field_contact_host kamailio 5.5

Hi Karsten,

Ok cool thanks for that I am testing now.

I also have the fun on a NAT’d interface so I am playing with setting 
advertised address as well!

Makes sense thank you for the reply.

Hi Jonathan,


I placed a new route and set the user part


$xavu(_tps_=>a_contact) = "sbc_a";$xavu(_tps_=>b_contact) = 
"sbc_b";

And for special cases I set the to user part to the To user for some silly pbx 
boxes.
Can also be that in this mode without setting a/b_contact the normal contact 
user part passes through, didn't test that.


Kind regards

Hi Karsten,

Thank you for your reply.

Thats interesting I will test it, so I see in the documentation it states;



$xavu(_tps_=>a_contact) = "...";

In your case what did you enter so that it just sets the user part?

I assume I could just set it to $sel(contact.uri.user) for example and it would 
then add that and the appropriate listen/ socket value ?

Many thanks!

In the meantime I assume other approach is hash tables as I have done before?

Yes I conditionally want to set it, I have tried this but not sure it has

Say for example I have request coming in from carrier on 10.10.10.10 interface 
and want to route to subscriber who is registered, so flow is simple its just;

Carrier--->kamailio-->subscriber

On branch route out I have set the contact_host to a particular IP address, 
however on_reply I want to change it again to another IP address, can I do that 
using the $xavu ?

So branch sees contact host as one IP address, and onreply I change it to 
another IP.

As currently if I set the Host it stays the same on both sides.

Does that make sense?

Hello,

There might be a spelling error below, you probably mean:

“$xavu(_tps_=>contact_host) = "2.2.2.2";
And this works fine but obviously sets the contact_host to 2.2.2.2 across both 
interfaces, I ideally want it to change between 10.10.10.10 and 2.2.2.2.”

Not sure if I understand your question correctly. You could just conditionally 
set the contact host to the different values, depending on your configuration 
logic.

Cheers,

Henning

Re: [SR-Users] topos xavu_field_contact_host kamailio 5.5

[Jonathan Hunter]

HI Henning,

Yes sorry late night  and thank you for reply.

Yes I conditionally want to set it, I have tried this but not sure it has 
worked to this point hence why I am wondering if I am missing something.

Say for example I have request coming in from carrier on 10.10.10.10 interface 
and want to route to subscriber who is registered, so flow is simple its just;

Carrier--->kamailio-->subscriber

On branch route out I have set the contact_host to a particular IP address, 
however on_reply I want to change it again to another IP address, can I do that 
using the $xavu ?

So branch sees contact host as one IP address, and onreply I change it to 
another IP.

As currently if I set the Host it stays the same on both sides.

Does that make sense?

Jon

Subject: [SR-Users] topos xavu_field_contact_host kamailio 5.5

Hi All,

I was wondering if anyone can help, and advise me if I am missing something 
when using topos in an environment where I have more than one interface for 
kamailio.

Essentially I would like to set the contact_host to 2 different values 
depending on the flow of the SIP requests, as we have a private LAN 
interconnect for example 10.10.10.10, and a public interconnect using 2.2.2.2 
(for example).

I notice there is xavu for A-side contact and B-side contact, but what about 
just the contact host?

As I have set for example;

modparam("topos", "xavu_cfg", "_tps_")
modparam("topos", "xavu_field_contact_host", "contact_host")
...
$xavu(_tps_=>contact_host) = "2.2.2.2";

And this works fine but obviously sets the contact_host to 8.8.8.8 across both 
interfaces, I ideally want it to change between 10.10.10.10 and 2.2.2.2.

How can I set more than one contact_host $xavu that topos can use? As my 
understanding is you can only set $xavu once, so is there another way to 
manipulate the contact_host on requests coming in and out on different 
interfaces?  I assume I am missing something? :)

Thanks in advance

Jon

Re: [SR-Users] Cockroachdb and kamailio 5.4

[Jonathan Hunter]

Noah,

Completely understand.

Good news however is with 5.4 and secure cockroach, it works for my 
requirements with the postgres api for location and subscriber table 
interaction, having created tables using scripts.

I will be using an API for other routing, and I can make sure of permissions 
and dispatcher files whilst in a containerised environment.

Will let you know if I run into any other issues. Thanks again!

Jon,

Realistically, this is alpha functionality, at best.  If you, and/or your 
organization, do not have the expertise, resources, and/or risk tolerance for 
this, I couldn’t in good faith recommend that you do it.

There are many other clustering technologies for MySQL and PostgreSQL that are 
mature, and *should* be compatible with the existing implementation.  Perhaps 
someone on the list can let us know if they’re using one of the following:

- MySQL Galera
- PostgreSQL replication (either using Pacemaker/Corosync or Zookeeper to 
provide automated failover and/or Master/Master)
- Vitess: 
https://github.com/vitessio/vitess<https://emea01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgithub.com%2Fvitessio%2Fvitess=04%7C01%7C%7C50369d445ce04ed280d608d8da614417%7C84df9e7fe9f640afb435%7C1%7C0%7C637499458574111672%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C1000=pPBfQYkCw801LNTrAj%2FxouPuUH7cClWm1YeyeR9YKAA%3D=0>
- Some other solution not listed here?

That being said, I’ve spend as much time on this as I can.  I solved the 
permissions module issue in this way:

For the schema update, it becomes CockroachDB specific, hence the need to start 
creating CockroachDB specific migration files.  For the  km_res.c change, this 
is where things are probably not ideal.  I’m hoping that Henning and/or Daniel 
can respond.  Essentially, CockroachDB stores all character/string datatypes 
the same way, and then presents this as a TEXTOID datatype.  I think the 
problem with moving this to the DB1_STRING type is that we *could* have memory 
overruns?  That’s just my guess.  Maybe it’s completely safe?

Thanks!

Realistically do you think you will be able to spend some time on this or do

I guess the primary requirements for me are being able to use these modules

I have started to work through it but I am pondering if in the short term I 
need to focus on a support database and look to migrate when available.

https://github.com/kamailio/kamailio/blob/5.4/doc/stylesheets/dbschema/xsl/postgres.xsl<https://emea01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgithub.com%2Fkamailio%2Fkamailio%2Fblob%2F5.4%2Fdoc%2Fstylesheets%2Fdbschema%2Fxsl%2Fpostgres.xsl=04%7C01%7C%7Cfd34312b504a4723068008d8d723ebe4%7C84df9e7fe9f640afb435%7C1%7C0%7C637495896580748983%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C1000=133XFlkVh6RSwjeJJR9rNgxJda%2BHp6kwwCiqjxEBrCc%3D=0>

You basically need to copy it to a new file and adapt the types in it to the 
cockroachdb types. If you execute “make dbschema” in the kamailio source tree, 
it will generate all the SQL files. Then you could generate the appropriate SQL 
files also for your database and it will stay in sync after future changes. 
There might be also a small extension necessary in the Makefile, but we can 
have a look to this later on.

About the questions why the SQL files are then also checked in after creation – 
because otherwise everybody needs to install the xstl dependencies just for 
installing Kamailio.

About the rand()/random() topic – I did not find anything in the LCR module as 
well. It might be obsolete. I would consider dropping this, maybe after asking 
on the sr-dev list for this again.

Cheers,

Henning

kamdbctl.pgsql

- I’ve updated the psql command for my preferences regarding output
- I’ve made the function checking more verbose
- I’ve added the gen_random_uuid() function (by adding pgcrypto to Postgres, 
it’s native in CockroachDB), this isn’t required, but we are using UUID for 
usrloc in production
- I’ve updated the GRANT commands so they’re compatible with both Postgres and 
CockroachDB

Re: [SR-Users] Cockroachdb and kamailio 5.4

[Jonathan Hunter]

Hi Noah,

Hope you are well?

I work as a consultant for a company in the UK, and I am building a new hosted 
telephony platform for them in docker initially, and as we are deploying across 
multiple servers they want to use cockroachdb to allow easy management of a 
cluster environment.

I could see from your posts you got it working using your own branch, and I 
wondered what changes you made to make things work correctly and what would be 
needed to get the kamailio dev’s to accept it into the main stream of code? 
(Happy to help here where I can).

Unless you will maintain your branch forever  Or are the changes small so its 
not too much of a concern? I just want to assess the risk really, and like you 
I think mainly we will just be using userloc and dispatcher for DB interaction 
so its positive to hear they work fine.  We would also be using rtpengine, 
routing data will be done via API so that should be fine. FYI Id like to run 
kamailio 5.4 initially.

I see your comments about table creation (in previous posts), that is the 
initial problem I am seeing when trying to use postgres based commands direct 
from a pgdump to create the kamailio database structure, does your branch 
contain all the creation scripts for the db/tables that I can use for testing?

Thanks again in advance  for the response!

Jon

Re: [SR-Users] kamailio 5.3.5 - none local route header

[Jonathan Hunter]

Hi Daniel,

Thanks for the reply.

I don’t see the CARRIER_IP listed as an alias, and I have only 1 domain listed 
and that’s local. I also toggled the register_myself parameter and it is still 
removing the none local CARRIER_IP.

The route header containing the CARRIER_IP doesn’t contain a from tag, apart 
from that it looks normal and I cant fine any reference to it locally.

I haven’t seen this before, however this is my first time implementing things 
in Azure and on centos 7. Its only on outbound calls as well, what other steps 
do you suggest if any?

Thanks for the reply.

that can happen if you have CARRIER_IP as value for alias global parameter or

Is this normal or configuration related?

Please can someone advise?

[SR-Users] kamailio 5.3.5 - none local route header

[Jonathan Hunter]

Hi Guys,

Sorry if this is too generic or silly a question but I am testing
kamailio 5.3.5 within Azure and its behind NAT.

I am having an issue with passing an ACK from our internal side back out to
the carrier side and it appears having run loose_route a none local 
route-header is
consistently being removed by kamailio at this point.

ie Route: 

Is this normal or configuration related?

As I am unsure within what scenario I would remove a route header which doesnt 
contain the local
Proxy IP.

Please can someone advise?

Many thanks

Jon

Hello,



It should be possible to use e.g. a timer route to periodically fetch the 
status from localhost with RPC commands and to feed this into the counters 
etc.. from xhttp_prom.



But the easier way is probably just to use an external collector.



Cheers,

Hi Guys,



We are running kamailio 5.3 in our dev environment with a view to using the

It works fine in terms of getting all the internal stats and groups, however is 
it possible to grab the dispatcher.list output/stats using the module?



I know there is a collector that does this and provides the dispatcher gateway

Hello,


I didn't spent time on understanding the exact issue, but from database point 
of view, do you want to avoid having two different tables for specific reasons, 
like external applications accessing it?


Have you looked at setting the server_id, maybe that can help to have the 
records grouped by each server.

[SR-Users] VRF routing with kamailio 5.2

[Jonathan Hunter]

Hi All,

Hope everyone in community is well.

I was wondering if anyone could let me know if VRF is supported with kamailio 
5.2 ?

Essentially I am looking to put kamailio between two SBCs and bridge the 
networks together.

So currently Server A 1.1.1.1 connects to Server B 2.2.2.2 and they pass calls 
fine, and I want to add kamailio in between without changing any IPs, so using 
VRF I have one network interface intA with 1.1.1.1 and the other intB with 
2.2.2.2.

What I want to do is listen on both interfaces, which is fine but bridge or 
force traffic between the two.

Is this possible with kamailio?  As doing force socket and listening on both 
1.1.1.1 and 2.2.2.2 kamailio just loops and routes to itself, and force socket 
doesnt help.

Do you have any suggestions?

Would running two instances of kamailio on same server help or even introducing 
to separate kamailio instances and force routing between the two for requests.

I am currently just testing with SIP OPTIONS and it is already proving tricky.

Any help or comments appreciated.

I appreciate this might not be the best solution however we have a lead time 
with providers to make changes which are proving quite slow and impractical so 
just trying to work a solution.

Thanks

[SR-Users] Strongswan on same Server in EC2 as kamailio 4.4

[Jonathan Hunter]

Hi Guys,

I have an issue with sending a BYE message back down a strongswan VPN tunnel on 
a server in the Amazon EC2 environment.

To get the configuration working correctly I have the Public IP address bound 
to a loopback virtual interface, and I also have kamailio listening to it.


Calls establish without issue, but when the called party send a BYE, I cant 
seem to force the SIP message down the correct interface.

Due to client confidentiality I need to be careful what information I send but 
does anyone have a similar configuration set up, and working, I am just looking 
for reasons as to why force_socket and mhomed=1 doesnt appear to force the BYE 
message via the Public Interface but the private IP address on the server as 
its a NAT'd environment.

So essentially call establishes;


CLIENT-(VIA IPSEC)-INVITE->(UDP)KAMAILIO PUBLIC 
IP>(UDP)KAMAILIO PRIVATE IP(TCP)->CLIENT B
   ||  |  |
   |<-(VIA IPSEC)-100 TRYING|<--100 
TRYING---|<--100 TRYING|
   | |  |   |
   |<-(VIA IPSEC)-180 RINGING---|<--180 
RINGING--|<--180 RINGING---|
   |||  
|
   |<-(VIA IPSEC)-200OK |<--200OK 
---|<--200OK |
   | || 
  |
   |--(VIA IPSEC)-ACk-> 
|---ACk->|---ACk-->|


   How can I ensure the BYE is forced out via the PUBLIC IP?

So I do this;
   CLIENT-(VIA IPSEC)-INVITE->(UDP)KAMAILIO PUBLIC 
IP>(UDP)KAMAILIO PRIVATE IP(TCP)->CLIENT B

   |<-BYE (VIA IPSEC)--|<--BYE 
|<--BYE ---|

   As it appears to be going from Private IP and not being pushed down the 
IPSEC tunnel

   CLIENT-(VIA IPSEC)-INVITE->KAMAILIO PUBLIC IP>KAMAILIO 
PRIVATE IP->CLIENT B

   |<-BYE --<--BYE 
|<--BYE ---|


   on the BYE I have tried;

   force_send_socket(KAMAILIO PUBLIC IP);

   However doesnt appear to work, is this an issue for ip routing on the server 
to push the BYE correctly down the IPSEC tunnel? or is it configuration related?

   Any comments welcome if people have had this issue before.


   Many thanks

   Jon

Re: [SR-Users] kamailio 4.4 registering to a SIP trunk provider using UAC then outbound routing to it.

[Jonathan Hunter]

Hi Daniel,


Thanks for the response.


My problem appears to be kamailio proxying the 407 response to the originating 
SIP trunk, which I appreciate it will do as its a proxy.


I presume if I want to absorb the 407 and handle only on the kamailio proxy 
which is the last point to the SIP carrier, this is more B2BUA, as I would 
normally have FreeSWITCH/ASterisk registering with the outbound sip provider 
and proxy the request via kamailio, where as in this case I am registering 
direct from kamailio so making it a little more complex in terms of handling 
the 407.

Normally there is no correlation between REGISTERs (to tell an other
server where to send incoming INVITEs) and outgoing INVITEs. So just do
whatever you normally do and be prepared to respond to a challend (with
auc_auth).

registered my kamailio Server with them using the uac module.

It is registered fine, and I can get inbound calls on the trunk.

My query is the best way to send outbound calls out via the registered sip 
gateway?

I would normally load balance using dispatcher if it was to IP authenticating 
providers, but as they are using registration, what would be best practice to 
send outbound calls via the registration which is establised with the uac 
module?

Is it just a question of doing it within the configuration file, as again they 
will look to auth requests as well with a 401/407 so I assume I can use 
uac_auth() for that.

Just wondering what other people have done if anything, is my other option is 
to register using a B2Bua on the same server, and leave kamailio just as a 
proxy.

Many thanks

Jon
