Hello,
I noticed that when i do calls behind NAT i'm getting this error when i
call fix_nated_sdp() :
"nathelper [nathelper.c:1659]: replace_sdp_ip(): can't extract 'a=rtcp'
IP from the SDP"
As far as i can see, all the ips on SDP are correctly replaced to a public
IP, so i don't understand the origin of this error.
This is the SDP received by Kamailio :

Best Regards,
Has anyone ever implemented DMQ replication of TOPOS data between
kamailio servers?
I'm trying to find the easiest (to maintain) way to implement this
replication, possibly without using an external database.

Hello, all have a problem with Kamailio presence, I have configured my
kamailio.cfg to handle dialog presence and facing issue in case of
subs_db_mode = 2 in case of mode 2 facing the following presence issue.
1. after hangup presence is still up
2. sometimes stuck in a ringing state
3. sometimes presence not came..etc
but in the case of subs_db_mode = 3 (DB ONLY) mode presence working fine
not facing any issue with this mode.
I noticed that sometimes Kamailio will throw the following message during
PUBLISH processing and it will not generate appropriate NOTIFY I also
verify inactive watcher subscription is there for that user and also a
proper entry in the dialog table.
MSG during PUBLISH processesing and it will not generate appropriate NOTIFY

Hello Kamailions,
I am running into the following issue.
The same setup I had working on 5.0, now I am using a 5.4 version of
Kamailio, but I do not believe it has to do with the version, more with
my ability to make errors...
I am trying to limit incoming calls by using the dialog module. The max
concurrent calls value I retrieve from a database.
But when I try to start Kamailio it will not because the dialog profile
is not defined...
These are my configured Dialog parameters:
# ---- Dialog params -------------
modparam("dialog", "default_timeout", 7200)
modparam("dialog", "db_mode", 0)
modparam("dialog", "dlg_flag", DLG_FLAG)
modparam("dialog", "hash_size", 4096)
#modparam("dialog", "detect_spirals", 1)
modparam("dialog", "profiles_with_value", "callee")
My check on the concurrent inbound calls:
route[CONCURRENT_IN]
{
#Add call to callee profile
#Check if callee has not reached inbound call limit
#Get max concurrent calls
sql_query("cc", "select max_calls_in from calllimit where
cust_id='$avp(custid)'", "ra");
$avp(maxcalls)=$dbr(ra=>[0,0]);
sql_result_free("ra");
$avp(concurrent) = 0;
get_profile_size("callee", "$avp(custid)", "$avp(concurrent)");
if( $avp(concurrent) = $var(max) )
{
xlog("L_INFO"," Call limit reached for customer
$avp(custid)\r\n ");
sl_send_reply("503", "No Lines Available");
exit;
}
set_dlg_profile("callee", "$avp(custid)");
return;
}
And the kamailio log error:
Dec 3 09:12:08 proxy01 kamailio[74102]: INFO: <core> [main.c:2833]:
main(): processes (at least): 21 - shm size: 67108864 - pkg size: 8388608

[core/route.c:1166]: fix_actions(): fixing failed (code=-6) at

Is someone able to see where I go wrong and point me in the right direction?
Thank you.

Hello!
I'm using a $TF variable in my config for some logging purposes. It was
providing the correct string with Kamailio version 5.3.8 on CentOS 6 and 8.
After updating to Kamailio version 5.4.1, the variable started to show
something else.
I also tried versions 5.4.2 and development 5.5.0 on CentOS 6 and the
problem still persists. With version 5.5.0_dev3 this variable shows "pG▒"
for me.
I was wondering if someone else is using it too with Kamailio version 5.4.1
or newer on different platforms and has this issue.
Thanks!

Folks,
I have a weird situation, when I enable Path header, kamailio behind a
Path proxy,
that kamailio doesn't recognise the ACK to CANCEL and tries to forward it.
Test scenario:
- voice.example.com is a stateless proxy with TLS/UDP bridging to kamailio.
- on the UDP leg to kamailio it will add a Path: header to REGISTER
UA1 = david is calling UA2 = charles and UA2 is sending 603
1 . UA1: preloaded route set (outbound proxy)
# this is the Path proxy
Route: sip:voice.example.com;transport=tls;lr
2. UA2: sends CANCEL 603
- kamailio immediately sends its (per-hop?) ACK
- kamailio forwards CANCEL to UA1
kamailio sent this (per-hop?) ACK
- the Route header is the internal UDP interface of the Path proxy
ACK sip:charles@192.168.1.7:37309;transport=TCP;ob SIP/2.0
Via: SIP/2.0/UDP

3. UA1 sends ACK
kamailio sees this
- top Via is path proxy
- 2nd Via is UA (caller)
- CSeq correctly matches the INVITE
- kamailio does not recognise this ACK from UA1(caller),
tries to forward it, and also resends 603 to UA1(caller) 3 times

Now kamailio should absorb this ACK, as it has already sent its
per-hop ACK. Instead I see
ERROR: <core> [core/forward.c:541]: forward_request(): cannot forward
to af 2, proto 3 no corresponding listening socket
I don't expect kamailio to forward anything at this point. The route
block is route[WITHINDLG] and it calls t_relay() normally.
route[WITHINDLG] {
if (!has_totag()) return;
# sequential request withing a dialog should
# take the path determined by record-routing
if (loose_route()) {
route(DLGURI);
if (is_method("BYE")) {
setflag(FLT_ACC); # do accounting ...
setflag(FLT_ACCFAILED); # ... even if the transaction fails
} else if ( is_method("ACK") ) {
# ACK is forwarded statelessly
route(NATMANAGE);
} else if ( is_method("NOTIFY") ) {
# Add Record-Route for in-dialog NOTIFY as per RFC 6665.
record_route();
}
route(RELAY); # we should absorb this ACK, no?
exit;
}
4. If I remove the Path proxy and kamailio is the TLS proxy at
voice.example.com the call flow works perfectly.
The ACK from caller (david) is absorbed.
5. Regular calls, when UA2 accepts the call, work fine. In-dialog
requests for BYE, from both UAs, work
correctly with this Path proxy. Each UA has the complete 5 element
route set( 2 x Path proxy + kamailio + 2 x Path proxy).
The working route set looks like this:
BYE sip:david@192.168.1.17:44925;transport=TCP;ob SIP/2.0
Via: SIP/2.0/TLS

Hello,
I note that I can use the ndb_redis server config parameter to specify connection details for my redis servers; I also note that the connection string can specify a “db” parameter which can be set from 0 to 9, with the default being 0.
I am looking for a way to dynamically set the db parameter. I do not which to add the same server with different names N times just to select a different db and having N times more connections to it than necessary.
It looks as though I can call redis_cmd(“svrN”, “SELECT dbN”, “init”); but will that propagate properly and set the correct db for all connections to my redis server for the lifetime of the request?
Ideally, I’d like to be able to specify an avp for the db, or have a function to set the db per request.
With every blessing,

Hi,
I want to remove some "Allow" features from my Kamailio SBC like I want to keep following only
Allow: OPTIONS, NOTIFY, INVITE, ACK, BYE, CANCEL, UPDATE, PRACK, REGISTER,
How can I achieve that?
Thanks,
