Hello!
I'm facing an issue 2/3 times a day with the following errors in the logs:

Hello,
during the Kamailio Developers Meeting 2023 in Dusseldorf that took
place last week, it was proposed to obsolete modules that seem to be
unmaintained and no activity about them was noticed during the past
years. It is quite some overhead in packaging them and trying to keep
them compiling when they have external dependencies, therefore such step
should spare some resources in the future.
The list (see below) was built based on the options of those present at
the meeting, now we want to discuss it on the larger communities of
developers and users. If you are using any of these modules or you think
any of them worth keeping, reply with the names of the modules that you
want to be kept.
The proposed action is to relocate the obsoleted modules to a new git
repository "kamailio-obsolete" to still keep some visibility to them and
in the eventually of future interest on any of them, it can be
reintroduced in the main repository.
Next is the initial list of modules proposed to be considered obsolete:
- app_java
- app_lua_sr
- app_mono
- app_python
- app_sqlang
- auth_identity
- call_control
- db2_ldap
- db2_ops
- db_cassandra
- db_perldvdb
- dnssec
- domainpolicy
- h350
- mediaproxy
- osp
- peering
- print
- print_lib
- pua_xmpp
- ratelimit
- uid_auth_db
- uid_avp_db
- uid_domain
- uid_gflags
- uid_uri_db
- uri_db
- xmpp
- xprint
Cheers,
Daniel

Hi,
Setup: kamailio acting as a UAC needs to register with a server whose
outbound proxy is DNS SRV based only, there's no A record on the proxy's
FQDN. The provider advertises two SRV records.
;; ANSWER SECTION:
_sips._tcp.sip.provider.com. 10 IN SRV 10 50 5061 sip11-sip.provider.com.
_sips._tcp.sip.provider.com. 10 IN SRV 15 50 5061 sip10-sip.provider.com.
Everything was working fine, until the provider changed the SRV priority,
putting a lower priority on the host that is actually down at the moment.
In this case, sip11-sip.provider.com is DOWN and sip10-sip.provider.com is
UP.
Now, what's happening is Kamailio tries to REGISTER with the lower priority
host, gets no reply back (TCP connection doesn't get established). It then
takes 30 seconds for Kamailio to try the host with the higher priority,
registering successfully. And so it goes for every re-register: failure =>
30 seconds => register OK.
The same happens for INVITES to the downstream: INVITE => timeout => 30
seconds => INVITE (other host 200 OK).
I've tried to play with TCP and DNS params, but so far no luck: no matter
what I did - it took the same 30 seconds for Kamailio to detect failure and
retry the secondary host.
Any suggestions will be highly appreciated.

Hi, I am trying to register an endpoint as follows:

Note that the Authorization username differs from the To-From username. This is intentional, as I am testing use of randomly generated credential .
This worked with this endpoint directly against Asterisk, for instance.
However, registering against Kamailio now, I am getting:
Nov 16 21:24:26 vs-rs01 /usr/sbin/kamailio[584855]: DEBUG: {1 2067 REGISTER 2053687751-32761-1(a)EH.BJI.BAE.HG} auth_db [authorize.c:503]: auth_check(): authentication username mismatch with from/to username
Even though I have this set in the config:
if (!auth_check("$fd", "subscriber", 0)) { // default 1, change to 0 to skip check
0 is supposed to mean no user checks performed.
I am doing this because I want to use the complex credentials for authentication, but want the endpoint to tell me the phone number in an INVITE to/from, instead of putting in the extremely long credential.
Is there a way to get Kamailio to accept different SIP User ID and Authentication ID fields?
Thanks,
Jawaid
Hello all,
I'm using the following Lua script to fetch data from Redis, which is in form of list:
function split(str, delimiter)
for token in string.gmatch(str, "[^" .. delimiter .. "]+") do
return token
end
end
function contains(mainString, subString)
return string.find(mainString, subString, 1, true) ~= nil
end
function longest_match_acode()
local currentSeconds = os.time()
local milliseconds = os.clock() * 1000
local ddate = os.date("%Y-%m-%d %H:%M:%S", currentSeconds) .. string.format(".%03d", milliseconds)
KSR.xlog.xinfo("starting date:" ..ddate)
local size = 0
local result
local acode = "29192"
local inputbcode = "4474173"
local delimiter = ":"
while size == 0 do
local currentSeconds = os.time()
acode = string.sub(acode, 1, string.len(acode) - 1)
KSR.ndb_redis.redis_cmd("srvN", "LRANGE price:" .. acode .." 0 -1", "r")
size = tonumber(KSR.pv.get("$redis(r=>size)"))
end
local left = 0
local right = size - 1
while left <= right do
local currentSeconds = os.time()
local milliseconds = os.clock() * 1000
local ddate = os.date("%Y-%m-%d %H:%M:%S", currentSeconds) .. string.format(".%03d", milliseconds)
resultRight = tostring(KSR.pv.get("$redis(r=>value[" .. right .. "])"))
resultLeft = tostring(KSR.pv.get("$redis(r=>value[" .. left .. "])"))
local bcodeLeft = split(resultLeft, delimiter)
local bcodeRight = split(resultRight, delimiter)
if contains(inputbcode, bcodeRight) then
KSR.xlog.xinfo("Input bcode contains bcode value from Redis: " .. resultRight .. " at index: " .. right .. " with date: " .. ddate)
end
if contains(inputbcode, bcodeLeft) then
KSR.xlog.xinfo("Input bcode contains bcode value from Redis: " .. resultLeft .. " at index: " .. left .. " with date: " .. ddate)
end
left = left + 1
right = right - 1
end
local currentSeconds = os.time()
local milliseconds = os.clock() * 1000
local ddate = os.date("%Y-%m-%d %H:%M:%S", currentSeconds) .. string.format(".%03d", milliseconds)
KSR.xlog.xinfo("ending date:" ..ddate)
end
function ksr_request_route()
if KSR.is_INVITE() then
longest_match_acode()
KSR.sl.send_reply("404", "Not found");
end
end
I'm getting the following warning in the log : WARNING: LUA {INVITE}: <core> [core/pvapi.c:340]: pv_cache_add(): pv cache limit is going to be exceeded - pkg memory may get filled with pv declarations
I think the issue is in the following lines:
resultRight = tostring(KSR.pv.get("$redis(r=>value[" .. right .. "])"))
resultLeft = tostring(KSR.pv.get("$redis(r=>value[" .. left .. "])"))
the list coming from Redis has around 30k items, which I'm iterating through using value[x] which is exhausting the pv declaration as per my understanding.
How to overcome this issue? Is it possible to save the list as an array variable and then iterate through that array?

Hi All,
I am playing around with the dlg_req_within to send a REINVITE to toggle some rtpengine parameters and this works fine.
The first time I use the command after tracking the dialog, it sends a REINVITE with an incremented CSEQ value.
However when I issue it again, it sends another REINVITE but with the same CSEQ value, so again 2 for example.
How can you ensure its incremented or can you set it somehow?
As would like to generate at least 2 reinvites per dialog.
Many thanks
Jon

I think it occurs only if $uac_req(evroute) is set to 1 and I define the event_route[uac:reply] route.
My uac_reply route is easy:
if ($uac_req(evcode)==200) {
xlog("L_INFO", "Registration for user $fU has been refreshed successfully.");
$sht(vtp=>asterisk_restarted) = $null;
route(SAVE_REG);
}
else {
xlog("L_INFO", "Registration failed: $uac_req(evcode)");
}
the SAVE_REG route is the following:
route[SAVE_REG] {
xlog("L_INFO", "Saving pbx registration...:$fU");
$var(maxExpiry) = MAX_PBX_REG_EXPIRY;
route(GET_CLIENT_ID);
sql_pvquery("ca", "select count(*) from pbxusers where user = '$fU'", "$var(pbxusersCnt)");
if ($var(pbxusersCnt)>0) {
if ($var(clientId) == 0) {
sql_query("ca", "update pbxusers set expiry = TIMESTAMPADD(SECOND, $var(maxExpiry), SYSDATE()), online=1 where user = '$fU'");
}
else {
sql_query("ca", "update pbxusers set client_id = '$var(clientId)', expiry = TIMESTAMPADD(SECOND, $var(maxExpiry), SYSDATE()), online=1 where user = '$fU'");
}
}
else {
sql_query("ca", "insert into pbxusers (user, expiry, client_id, online) values ('$fU', TIMESTAMPADD(SECOND, $var(maxExpiry), SYSDATE()), '$var(clientId)', 0)");
}
}
And GET_CLIENT_ID route is:
route[GET_CLIENT_ID] {
$var(clientId) = 0;
if (is_present_hf("X-AT-ClientId")) {
$var(clientId) = $hdr(X-AT-ClientId);
}
}
Any idea, is it a bug or I do something wrong in config files?

Hello Daniel,
I do not see any “failed to send request with authentication”.
The next CRITICAL log appears after calling uac_req_send():

Now we use kamailio 5.7.2 and no crash has come, but the critical logs above exist.
I saw a ticket in github: https://github.com/kamailio/kamailio/issues/3522, may the crash be similar or the same to that?
I will make a try next week with downgrading to 5.6.2 and try to reproduce the crash.

Hello,
do you also get error log messages that include "failed to send request with authentication"?
Which CRITICAL log appears when you call uac_req_send()? You pasted a couple of them in the initial email?
Cheers,

Hello,
I used kamailio version 5.6.2. I refreshed to 5.7.2 today.
As I remember it was in kamailio long time ago therefore I could skip evroute route.
But this CRITICAL log appears always when I call uac_req_send().
I call it with settings:
$uac_req(auser) = $var(username);
$uac_req(apasswd) = $var(password);
Where username and password are retrived from web service before call.
In event_route I got first 401 after 200.
