Hello,
I'm interested in using the htable and/or mtree modules to keep my
aliases and did lookups in memory to minimize the amount of SQL lookups
that are being performed. It's easy enough to use htable to cache a
single value after it is retrieved but what I'm not clear on is how I
can do it when SQL returns multiple destinations. Consider the following
query and returned results:
SELECT username,domain,CAST(q_value AS CHAR) FROM aliases where
alias_username = '10001' AND alias_domain = 'us.sip.globeop.com' AND
active = '1' ORDER by q_value;
+----------+--------------------+-----------------------+
| username | domain | CAST(q_value AS CHAR) |
+----------+--------------------+-----------------------+
| 8500 | us.sip.globeop.com | 1.000 |
| 3874 | us.sip.globeop.com | 1.000 |
| 7050 | us.sip.globeop.com | 1.000 |
| 2100 | us.sip.globeop.com | 1.000 |
In my existing script I just append the results as branches and all
works well but I end up with a lot of unnecessary SQL traffic. I see the
htable supports array but I'm not sure how to go about assigning
multiple values to a single key to use later. How can I take the above
results and store them in memory for use by other transactions?
Thanks,
Bob

Hello,
during the testing period of Kamailio 3.1.0, while running it at
voipuser.org, I had the chance to watch live and analyze a SIP scanning
attack. Yesterday I noticed another one by looking at Siremis 2.0
charts, therefore I wrote an article with some hints about what you can
use to protect your SIP services within Kamailio configuration file.
You can read it at:

Hope is going to be useful for many of you!
Cheers,
Daniel

Hello,
I'm having problems with my kamailio, my phones are unable to register into
the Proxy. I have been checking with ngrep-sip and all i'm receiving is many
REGISTER from the phones but never getting some response from the Proxy
The Proxy has a public IP and the phones are behind NAT. The weir thing is
that my logs are not showing any output...and as you can see on the script,
i have a section to receive REGISTER requests....
if (is_method("REGISTER")) {
if (!save("location")) {
sl_reply_error();
}
exit;
}
Thanks in advance for your help
Hi all,
I want to enable pike module based on IP addresses. I mean ... I don't
want to check if requests from some specific IP addresses trigged the
Pike's threshold. but for all other IP addresses I want to check it.
I was thinking about using some kind of IP addresses' whitelist. The
userblacklist module has some whitelist but it's based on
username/domain not IP addresses.
Can someone please give me some advice how to implement it properly. Is
there any module that will allow me to do it properly?
Best Regards,
Miguel Baptista
Dear all,
Does anyone can explain how Dispatcher module is sending calls to the
gateways in the different states?
I mean if I have 3 gateways and the one of them is in Probing mode why
Dispatcher is continuing sending there calls? Why this gateway is not
changing from Probing to Inactive since is not replaying to OPTIONS messages
send by Kamailio?
Configuration:
modparam("dispatcher", "flags", 2)
modparam("dispatcher", "ds_ping_interval", 5)
modparam("dispatcher", "ds_probing_mode", 1)
modparam("dispatcher", "ds_probing_threshhold", 2)
modparam("dispatcher", "dst_avp", "$avp(s:dst_avp)")
modparam("dispatcher", "grp_avp", "$avp(dsgrp)")
modparam("dispatcher", "cnt_avp", "$avp(i:202)")
modparam("dispatcher", "ds_append_branch", 0)
using db for gw:
setid 123,destination sip:xxx.xxxx.xxx, flag 0 ...
in ROUTE:
if(ds_select_domain("$avp(s:disp_dstgrp)", "4"))
in Failure Route
if(!ds_next_domain())
I want Dispatcher when it sees a node gateway that is dead , to Not send any
other calls.
Thank you in advance

Hello all,
I am conducting some load testing and need to create 50,000 accounts on kamailio.
I want to write a shell script to add 50,000 users. Kamctl add [user] [password] prompts for a password and I checked kamctl -help and there is no option for providing password along with the command.
Is is possible to disable password and run my script?
Thanks
Sid

Hello SER Team,
We have made SER listen on two ports via adding this command
(listen=eth0:5060 eth0:5062) in ser.cfg file. Now we are able to get
the server listening on two ports as 5060 & 5062 and it is sending 200
OK for the user agents which try to communicate on both the ports. SER
is able to register two user agents, one on 5060 and one on 5062. But
when we are trying to make a communication between the two registered
user agents (i.e. one on 5060 and other on 5062) then no communication
is possible (i.e. we cannot make calls and chats). Though when the two
user agents are registered on same port (i.e. both UAs on 5060 or both
UAs on 5062) then communication is possible between the two clients
(i.e. we can make calls and chats).
Can you people please guide me through that how can I make the 2 UAs
registered to SER on different ports (i.e. one on 5060 and other on
5062) communicate with each other (i.e. they can make calls and
chats).
I have attached a log as well which shows the same problem. This is a
wireshark captured output on the machine which has SER installed.
Thanks and Best Regards

Hi All,
Asterisk><kamailio 3.0.2><sip carrier
I see normal tansactions until the carrier send back a '486 Busy Here'
then kamailio sends an 'INVITE SDP', then I get a '100 trying' from
the carrier then a '482 Loop Detected" from the carrier.
Shouldn't kamailio relay the 486 to the original invite server and not send SDP?
I'm guessing I'm not handling 486 propperly in my config:
http://pastebin.com/crfMe81D
Here is a pastebin of the call graph:
http://pastebin.com/rnQZDyFU
I was thinking about including this in my failure route:
if (t_check_status("486")) {
append_branch();
t_relay();
}
Would that do any good?
Thanks.
