You can always use an outside service, which communicates with Kamailio asynchronously via a variety of channels. See the various message brokers, EVAPI, etc.

@Alex Balashov 

I thought about EVAPI but I'm afraid it will bring a lot of unnecessary CPU
overload, and in my case I need to have maximum CPS on this server (used
for as STIR/SHAKEN with a REST API...)-
Will have a try with EVAPI.

[Sergio Charrua via sr-users]

@Ben Kaufman :  thanks, I will try that!

@Nick Digalaks : isn't that necessary to have a correct http async
transaction? the async_http module does make/need the TM module to be
loadedand all examples I got for the async_http module had t_newtran()
method added prior to executing http request

The term 'stateless' in the scope of a SIP proxy doesn't mean to keep track of 
the session (or the dialog).  It means tracking the state of the transaction.  
In order to pause the current transaction and resume it (using 
http_async_query()), a stateful transaction must be created within Kamailio - 
and you've done this when you call `t_newtran()`.  As a recommendation, rather 
than using `sl_send_reply()`, `t_reply()`, or `t_send_reply()`, just  use 
`send_reply()`, which will send the reply statelessly if there's no 
transaction, and statefully if there is a transaction.


If you want to make your replies LOOK stateless to request source, disable 
automatic 100 Trying from the TM module.

Hi all!


For testing purposes, while I am waiting for the ST/SH REST API to be available 
from other teams, I developed a small python REST API that returns a mockup of 
a JSON object with some of the required values.
The kamailio script, completely stateless as I do not need to keep track of the 
sessions, iterates through one of the JSON branches and adds the destination 
URLs to the Contact header and replies a SIP 300 Multiple Choices.
This works: the UAC does receive the SIP response with the Contacts , but it 
also receives a SIP 500 error message right after, and I can't figure out why. 
And i bet this is simple to solve
Any clue? I'm aware I'm not processing ACK messages, but the sl_send_reply 403 
should do the trick right? ... at least while testing

Also, as this is a stateless script, is there another way of using async http 
or making http requests to a REST API without having to use TM Module?

Thanks in advance.

[SR-Users] Solution found: Race condition in dialog on 422 reply deletes variables.

[Benoit Panizzon via sr-users]

Hi all

I have found another solution:

Don't use: setflag(FLT_DLG);

call dlg_manage() on every message entering request_route before trying
to set dlg_vars.

On a 422 reply I now get two CDR, but that is OK as long as I have
correct dlg_vars on the second almost identical call (endpoint
immediately re-sending the invite with smaller session timer) which is
then connected and which I need for billing.

Mit freundlichen Grüssen

-Benoît Panizzon-

[SR-Users] Re: Kamailio Admin Book email

[sadik.oualla.mohamed--- via sr-users]

Hello Daniel,

Following your feedback regarding the incomplete address in my  request, I have 
resubmitted the form with the corrected address format and included "N/A" for 
the VAT number, as I am located outside the EU (in Morocco).

I think that the updated details meet the requirements, but please let me know 
if there's anything further needed from my side to process the purchase 
successfully.

Thank you for your attention to this matter, and I look forward to your 
confirmation.

Sincerely yours, 
Mohamed.

[SR-Users] Re: Kamailio Admin Book email

[Daniel-Constantin Mierla via sr-users]

Hello,

as you can see on the page with the form for requesting to purchase the
book, incomplete requests are not making it through:

"The requests with invalid or incomplete values for the required fields
are ignored."

Searching over the discarded requests, the provided address in your
message is incomplete. Those details are required by Eu/German laws for
invoice and income taxes.

Cheers,
Daniel

[SR-Users] customizing the ds_ping_interval dispatcher parameter for destination

[Giuseppe Pandolfi via sr-users]

Hi,
I have one question about dispatcher module in kamailio V.5.3.1.
Why the ds_ping_interval parameter is only global value? Is it possible 
introduce the customization value for single destination?
Customization from destination is already possible for ds_ping_from parameter 
using special attributes in destination list file or db table, is it possible 
introduce the same management for ds_ping_interval?

Thanks,
Giuseppe
