Dear Kamailio users,
I am trying to use a python script using the module app_python3 to do some
billing calculations.
The only argument i want to pass to the python script is duration which i
calculate in
event_route[dialog:start] {
$dlg_var('call_start') = $TS;
event_route[dialog:end] {
$var('v_duration') = $TS - $dlg_var('call_start');
So my $var('v_duration') has the duration of the call in seconds.
Then i execute from my kamailio.cfg:
python_exec("calculateCost","$var('v_duration')");
The script works randomly - sometimes all is good and sometimes it throw
error :
app_python3 [python_support.c:156]: python_handle_exception(): apy_exec:
calculateCost(4): Unhandled exception in the Python code:
TypeError: an integer is
required (got type NoneType)
The above exception was
the direct cause of the following exception:
Traceback (most recent
call last):
File
"/etc/kamailio/kamailio-python.py", line 282, in calculateCost
duration =
int(duration)
It looks like the kamailio log show calculateCost(4) so argument 4 is
passed to python function but once it executes it appear like there is no
string/integer but NoneType argument.
I cannot figure this out why this randomly happens - maybe it's an
app_python3 module issue?
Looking to hear back from you!
BR,
Tom
Dear,
I am trying to make a test to see how can webrtc work in kamailio and tls.
I was try some link :
1 <https://github.com/havfo/WEBRTC-to-SIP>. https://github.com/havfo/WEBRTC-to-SIP <https://github.com/havfo/WEBRTC-to-SIP>
2. https://telecom.altanai.com/2018/09/04/kamailio-webrtc-sip-server/ <https://telecom.altanai.com/2018/09/04/kamailio-webrtc-sip-server/>
And Generate CA from the link:
https://www.kamailio.org/dokuwiki/doku.php/tls:create-certificates <https://www.kamailio.org/dokuwiki/doku.php/tls:create-certificates>
Then, I tried to login with simpl5 and i got the message back
Disconnected: Failed to connet to the server
I do not know how can i fix that issue, look like TLS configure has issue with that. the log is showing something like
Jul 14 17:56:16 ip-172-31-44-170 sbin/kamailio[13813]: ERROR: tls [tls_server.c:1283]: tls_h_read_f(): protocol level error

My tls.cfg is :
[server:default]
method = SSLv23
verify_certificate = yes
require_certificate = yes
private_key = /etc/certs/my.domain/key.pem
certificate = /etc/certs/my.domain/cert.pem
ca_list = /etc/certs/demoCA/cert.pem
[client:default]
verify_certificate = yes
require_certificate = yes
Please help me to register sipml5 or how can i create CA for TLS in kamailio to use with webrtc.
Thank all.
Hello,
Does anybody know how i could change white filter in siprelpy in sems?
In Kamailio, I got "200 OK" from UE, then add a new header (SBC: mt-reply)
and send it to sems server. The sems server remove it:
[#7f410fbfb700/4560] [inplaceHeaderFilter, HeaderFilter.cpp:226] DEBUG:
erasing header 'sbc' by whitelist
I really don't want to remove it.
Actually if I knew how i active profile for sip replying in sems, I would
be able to solve this.
Thanks with regards.

Hello guys,
do you know if it’s possible for a kemi script to know if a name is defined (with #!define) in kamailio.cfg? It would be useful to modify kemi script logic depending on feature/module presence.
Thanks in advance for your help.
Regards,
Riccardo

Greetings.
I'm trying to set up annoncement playback for both parts of the call. I
have to play the file after the connection is established. Stop_media (all)
must be executed before playing
It turns out the construction:
....
block_media ("all");
play_media ("all file = / etc / kamailio / sounds / mg1.wav");
Can't find a way to do
unblock_media ("all");
after the file has finished playing.
There are no sip messages in this process. The call has already been
established.
Hello,
I have a kamailio cluster with two nodes
kamailio-1.local: 10.101.2.119
kamailio-2.local: 10.101.2.247
with dmq configs:
kamailio-1:
modparam("dmq", "server_address", "sip:MY_IP4_ADDR:5060")
modparam("dmq", "notification_address", "kamailio-2.local:5060")
kamailio-2:
modparam("dmq", "server_address", "sip:MY_IP4_ADDR:5060")
modparam("dmq", "notification_address", "kamailio-1.local:5060")
All works fine, but kamcmd dmq.list_nodes on kamailio-1.local show me:
{
host: 10.101.2.247
port: 5060
resolved_ip: 10.101.2.247
status: active
last_notification: 0
local: 0
}
{
host: kamailio-1.local
port: 5060
resolved_ip: 10.101.2.119
status: active
last_notification: 0
local: 0
}
{
host: kamailio-2.local
port: 5060
resolved_ip: 10.101.2.247
status: active
last_notification: 0
local: 0
}
{
host: 10.101.2.119
port: 5060
resolved_ip: 10.101.2.119
status: active
last_notification: 0
local: 1
}
and kamailio-2.local show me:
{
host: kamailio-2.local
port: 5060
resolved_ip: 10.101.2.247
status: active
last_notification: 0
local: 0
}
{
host: 10.101.2.119
port: 5060
resolved_ip: 10.101.2.119
status: active
last_notification: 0
local: 0
}
{
host: kamailio-1.local
port: 5060
resolved_ip: 10.101.2.119
status: active
last_notification: 0
local: 0
}
{
host: 10.101.2.247
port: 5060
resolved_ip: 10.101.2.247
status: active
last_notification: 0
local: 1
}
So there are only two hosts in the cluster, but there are 4 records in
dmq.list_nodes. Also in sip trace I can see that kamailio send DMQ messages
to itself too (because it ip marked as local: 0 I think).
Is it ok? Is it normal behavior? What should I do to fix it? Should
multi_notify and DNS name with 2 A records fix it (and why?)?

Hi Alex,
By subscriber management I mean, auth_db module which actually works on subscriber table to add or alter sip account for authentications.
Auth_db Module (kamailio.org)<https://kamailio.org/docs/modules/4.4.x/modules/auth_db.html#auth_db.f.auth…>
So, similar like usrloc module which you mentioned having JSONRPC commands to alter Location table.
I am looking for JSONRPC Command for subscriber module as well.
As far as my understanding, currently there is no JSONRPC command available for subscriber table.
So, if this is currently a known not offered feature / limitation shall we raise it as feature request if others also agree to its usefulness.
What I'm seeking is more of an acknowledgment that this feature doesn't exist & have it's benefit. As I can see other community members either ends up directly interacting with DB for subscriber table provisioning. Maybe I can contribute on this too.

I am not 100% sure what you mean by subscriber management, but if you mean what I think you mean, these might be the droids you’re looking for:

Hi Team,
Greetings!
I was trying to use HTTP to do the subscriber management (CRUD operations) & for that I am using JSONRPC-S module (JSONRPC over HTTP). But like other modules e.g. dispatcher, location I am unable to find any RPC commands for doing subscriber management (checked in auth_db) module. So is there a way to achieve subscriber management using JSONRPC over HTTP.
Few HTTP examples which I am using for dispatcher module are given below. Similar commands I am looking for subscriber management as well.
curl http://localhost:8081/RPC -H "Content-Type: application/json" -d " {\"jsonrpc\":\"2.0\",\"method\":\"dispatcher.add\", \"params\":[2, \"sip:127.0.0.1:5061\"], \"id\": \"1\"}"
curl http://localhost:8081/RPC -H "Content-Type: application/json" -d " {\"jsonrpc\":\"2.0\",\"method\":\"dispatcher.remove\”, \"params\":[2, \"sip:127.0.0.1:5061\"], \"id\": \"1\"}"

Hello,
I'm testing DMQ_USRLOC modulo between two Kamailio servers (A) and (B)
The two servers share the same domain and using Amazon Route53 to
distributes 50% requests each Server.
The problem is when I try to make a call from user A (registered on
kamailio A) and the user B (registered on Kamailio B).
The call follow this flow:
User A --> KamailioA --> UserB
go directly to userB because KamailioA know, via DMQ_USRLOC IP and port
of UserB. With some Softphone the call work with audio without problem;
with other Softphone USERB never answer the INVITE sends from Kamailio.
Is it possible use this flow?
USER A --> KamailioA --> KamailioB --> User B
to resolve this kind of problem or is there other available option?
Thank you

Hi to all,
In a scenario, we need to change the destination of users' registration requests when they send the first 'Register' to Kamailio-A and it replies 401 to the user, next time the user sends 'Register' to Kamailio-B.
User------Register-------> Kamailio-A
User<-----401--------------Kamailio-A
User-------Register--------> Kamailio-B
RFC says we can't use the Record-Route for register because it doesn't create a dialog.Is there any option, header that Kamailio-A puts in the 401, and after that users send register to the Kamailio-B?
Thank you.BR,Hossein
Hello,
Kamailio SIP Server v5.4.6 stable release is out.
This is a maintenance release of the latest stable branch, 5.4, that
