implementing call-quota with dialog module
by Aft nix 08 Oct '12

08 Oct '12

Hi, I'm trying to implement a "callquota" based on destination domains. The idea is following: every destation domain has a limit of, say 50 calls. As the sip clients are registered with the "destination domains", i've extracted the domain using "$fd" because it results as same value as destination domain. Problem is, i wanted to have separate quota for each domains. But it seems, that the quota is reached "as total" not as per domain basis. Another thing is, the number of calls reported by it is also unusually large than actual calls. This is implemenated as bellow: #!ifdef WITH_CALL_LIMIT modparam("dialog","enable_stats",1) modparam("dialog","dlg_flag", DLG_FLAG) modparam("dialog","hash_size", 4096) modparam("dialog", "profiles_with_value","callquota") modparam("dialog", "default_timeout", 300) modparam("dialog", "dlg_match_mode", 2) modparam("dialog", "detect_spirals", 1) modparam("dialog", "db_mode", 0) #!endif #!ifdef WITH_CALL_LIMIT if (is_method("INVITE")) { dlg_manage(); $var(100) = 0; get_profile_size("callquota", "$fd", "$var(100)"); if ($var(100) >= 50 ) { xdbg("DEBUG: Simultaneous calls limit reached"); sl_send_reply("503","Simultaneous calls limit reached"); exit; } set_dlg_profile("callquota","$fd"); if (get_profile_size("callquota","$fd", "$var(100)")) { xdbg("DEBUG: there are $var(100) total calls for $fd"); } } #!endif Thanks in advance. -- -aft

Newbie question about RLS/XCAP/batch'd NOTIFYs
by Dmytro Bogovych 06 Oct '12

06 Oct '12

Greetings. I try to make iOS voip application with presence information. iOS does not let too frequent network updates from server side when runs in background mode. So I cannot rely on plain PUBLISH / SUBSCRIBE scheme - it leads to restart of application by iOS in many cases. Please see this post for details: https://devforums.apple.com/message/565667#565667 The question. Can Kamailio provide way to reduce the number of NOTIFYs? I see it as 1) iOS application creates & uploads RLS via XCAP 2) iOS application asks server about changes in presence information once per 10 minutes or when application goes to foreground state. The best way is to receive single batch'd NOTIFY answer for all watched peers. Is it possible to implement with kamailio? Thank you :)

compilation warnings

Hi, On a Gentoo Linux system I'm getting the following compile-time warnings (kamailio-3.3.1 ebuild): * python_msgobj.c:529:5: warning: dereferencing type-punned pointer will break strict-aliasing rules * ld_con.c:241:4: warning: implicit declaration of function 'ldap_simple_bind_s' * perl.c:340:2: warning: null argument where non-null required (argument 2) * perl.c:340:2: warning: null argument where non-null required (argument 1) Hopefully I can just ignore these messages. Thanks, Vieri

by Juha Heinanen 05 Oct '12

is Homer Capture Agent 4 hep protocol incompatible with Kamalio 3.3 sipcapture module? in captagent.xml i set core_hep.conf version to 2, but looks like kamailio is not able to parse the messages: Oct 5 12:40:18 siika sip-proxy[6779]: INFO: <core> [parser/parse_fline.c:145]: ERROR:parse_first_line: method not followed by SP Oct 5 12:40:18 siika sip-proxy[6779]: INFO: <core> [parser/parse_fline.c:242]: ERROR:parse_first_line: bad message Oct 5 12:40:18 siika sip-proxy[6779]: ERROR: <core> [parser/msg_parser.c:705]: ERROR: parse_msg: message=<#002#020#002#006#023ĳ��bg#012�bg#012#002�nP#037#035#010> Oct 5 12:40:18 siika sip-proxy[6779]: ERROR: <core> [receive.c:146]: ERROR: receive_msg: parse_msg failed in kamailio config i have modparam("sipcapture", "capture_on", 1) modparam("sipcapture", "hep_capture_on", 1) -- juha

Does Kamailio support ECDHE ciphers for TLS?
by AJ 05 Oct '12

05 Oct '12

Hi, I have Kamailio 3.3.1 working fine with TLS 1.0, running on CentOS 6.3 However, now I want to use some ECDHE ciphersuites, for instance: ECDHE-ECDSA-AES128-SHA I have built an appropriate OpenSSL (1.0.0j) in CentOS to support this, and have generated the appropriate certs: openssl ecparam -out ca-privkey.pem -name secp256r1 -genkey -outform pem openssl req -x509 -new -key ca-privkey.pem -out ca_cert.pem -outform PEM -days 3650 openssl ecparam -out privkey.pem -name secp256r1 -genkey -outform pem openssl req -new -nodes -key privkey.pem -outform pem -out cert_req.pem openssl ca -keyfile ca-privkey.pem -cert ca_cert.pem -in cert_req.pem -out cert.pem However, when I try to connect from my phone I am always getting: Oct 3 20:27:54 /usr/sbin/kamailio[2905]: ERROR: tls [tls_server.c:1190]: TLS accept:error:1408A0C1:SSL routines:SSL3_GET_CLIENT_HELLO:no shared cipher Oct 3 20:27:54 /usr/sbin/kamailio[2905]: ERROR: <core> [tcp_read.c:1127]: ERROR: tcp_read_req: error reading If I use the OpenSSL s_server test-tool, I can connect from my phone just fine with these certs: openssl s_server -accept 8888 -cert cert.pem -key key.pem -pass stdin -CAfile calist.pem -cipher ECDHE-ECDSA-AES128-SHA Does Kamailio support ECDHE ciphersuites? If so, what am I doing wrong? Thanks! AJ

Kamailio question
by Jostein Aardal 05 Oct '12

05 Oct '12

Hi! I am a student at Oslo and Akershus University college of applied sciences. I'm working on a project where I am supposed to setup a kamailio server. Up until now I have been able to install kamailio and add a user. When I use a sip-client I am able to register and authenticate this user. And I am able to make calls between different users, as long as they both are registered on the same server. But when I try to make a call between users that are registered on different servers/proxies I fail to establish the call. When I look at the sip-messages in wireshark, I see that there is a message "407 proxy authentication required". I thought that enabling "multidomain" in kamailio.cfg would fix this problem, but it doesn't. What I have written in the kamailio.cfg-file is: #!define WITH_MYSQL #!define WITH_AUTH #!define WITH_USRLOCDB #!define WITH_MULTIDOMAIN #!define WITH_ALIASDB #!define WITH_DEBUG yours Jostein Aardal Oslo and Akershus University College of Applied Sciences

Client info
by Sangeeta Shah 04 Oct '12

04 Oct '12

Hello All, I am trying to use Kamailio 3.3 configured as a presence server and rls server with integrated XCAP. I am trying to test the presence and rls functionality with clients such as Jitsi (doesn't seem to support rls and doesn't let me specify presence rules per contact) and Boghe (doesn't seem to be behaving as expected!). Anyone recommend other clients that work for the functionality I described above. Thanks, Sangeeta -- Sangeeta Shah

Kamailio LCR - From Uri
by Fatima Chahrour~Vanrise Support 04 Oct '12

04 Oct '12

Dears, Am able to route call using LCR module from anywhere. I need to use certain option in the lcr tables in order to specify the ip of which calls is generated. I suppose that the From_uri column in LCR module meets my requirement, yet am not able to make it work and confused after reading several docs. My question is in what form should the from_uri column be? Is the ip enough? Are the Load params used below missing? modparam("lcr", "db_url","mysql://openser:openserrw@localhost/openser") modparam("lcr","lcr_gw_table","lcr_gw") modparam("lcr","from_uri_column","from_uri") modparam("lcr","priority_column","priority") modparam("lcr","gw_uri_avp", "$avp(i:709)") modparam("lcr","ruri_user_avp", "$avp(i:500)") modparam("lcr", "flags_avp", "$avp(i:712)") modparam("lcr","lcr_id_avp","$avp(s:lcr_id_avp)") What should I change in the routing script to consider the from_uri? if (!load_gws("1")) { sl_send_reply("503", "Unable To lOad GatEwAyS"); exit;} if(!next_gw()){ sl_send_reply("503", "Unable To fInD a gateWaY"); exit;} Thanks in advance, F Chahrour
