Re: [SR-Users] Limit cps per destination gw

Jon,

You can check one of my old blog posts related to this

https://blog.provoip.org/2017/02/kamailio-limit-cpscpmconcurrent-calls.html

It's based on htable and quite easy to implement

Hi,

pipelimit allows dynamic queues from a DB. But if you want to limit
concurrent calls, the best option is probably using dialog profiles with the
dialog modules. For a cps limit you could also just use htable.

Cheers,


Hi Henning

No, concurrent calls is not the issue. CAPS is.

pipelimit seems promising. Don't like the db backend requirement. I guess I can
use dbtext, leave it blank and create pipes on demand with pl_check and read
the limit from a custom header. This system doesn't have db backend as it's a
loadbalancer for multiple kamailio servers and needs to be fast as hell.


thank you

Jon

[SR-Users] Contact header modification - Kamailio

2022-08-01 Thread Ankit Jayswal

Hello Team,

I am in need to modify the contact header in Kamailio before sending an
INVITE request to the SIP trunk provider. Basically the IP address I need
to modify in the contact header. Please suggest a better way to do this.
Below is an example.

*OLD (Existing):*
Contact: 

*NEW (Needed):*
Contact: http://10.52.26.98:5060>*>

I tried various functions from the textops module but no hope.
I am looking for a function that can replace the contact header's value.
Please help me with this.

Hello,

the topos module can do that, among other things. Alternatively there is also 
the topoh module, which do not need any backend storage.

Re: [SR-Users] Newbie - Installation Issue - ERROR: could not load the script in /usr/lib/kamailio//kamctl/kamdbctl.mysql for database engine MYSQL

2022-08-01 Thread Henning Westerholt

Hello,

indeed the package seems not to contain anything related to db_mysql or other 
SQL databases. Maybe somebody that knows more details can comment, it could be 
just not included there.

https://pkgs.alpinelinux.org/contents?repo=main&page=1&arch=x86_64&branch=edge&name=kamailio

Maybe you can just try the official Debian or Ubuntu packages from 
deb.kamailio.org, they should work.

Cheers,

Henning

I suspect this must have been addressed before but I couldn't find a way of

I'm using Alpine Linux.
Used "apk add kamailio"   to install  Kamailio 5.5.4-r1

Following the Instructions on

At the section for "Creating MySQL database"  I modify the file and then run

Re: [SR-Users] Sharing Database between three kamailios

2022-08-01 Thread Henning Westerholt

Hello,

you can share a database between different Kamailio server. Especially if they 
access only read-only, this is pretty much a standard scenario.

Regarding keeping a table for the active calls, the dialog module allows you to 
easily track current calls. It can also save the information in a database.

Otherwise you can of course also do your own solution, e.g. with the sqlops 
module.

Cheers,

Henning

Subject: [SR-Users] Sharing Database between three kamailios

I have three Kamailios in three different servers which are dispatching calls 
to 9 asterisks in three different servers using load balancing. All these 
Kamailios are using databases installed on that servers. As the entries of the 
dispatcher table are the same for all the Kamailio, so I want that these 
Kamailio use a single database installed on one of the servers. All these 
Kamailios instances should use the same database which is common between them. 
And also I want these Kamailios to write into the database by creating a table 
that stores all the active calls in three Kamailios. Is it possible? How can I 
do it? Please guide me with somewhat explanation as I am not this much expert 
in Kamailio.

Waiting for a quick response.

Hello,
Thanks for your reply, but I am looking to replace the value in the Contact

I tried,
*assign_hf_value("Contact", "http://sip:00912269240xxx@10.52.26.98:5060>>");*

But that is not working properly, it assigns value but previous value also
remains in it.

Before you do this, I would ask yourself why you’re doing this, and whether 
it’s a good idea from a technical point of view.

Re: [SR-Users] Contact header modification - Kamailio

Hello,
Yes, actually my call flow for outbound calls is, Kamailio => Asterisk =>
Kamailio (route(PSTN)). SIP trunk is available at Kamailio server.
So, when final outbound INVITE goes to the SIP trunk provider it expects a
particular Contact header IP, instead of Asterisk server IP.

Hi Ovidiu

I have a couple of performance questions.

First, seems like the module doesn't use it's own timer processes. You can set
it to the secondary timer but I don't think it would be a good idea. 

Did you test high load on short intervals? I'm expecting about 1000cps and
about 100 pipes and I'm wondering what interval I could use not to flood the
timer.

The other solution suggested is htable. I wonder which one could be chapest for
load.


thanks,

Jon
