Diversion header authentication
by phillman25 10 Apr '13

10 Apr '13

Thank you Daniel and Morten for your assistance and prompt reply. To use the tobody transformation, i see that i would need to upgrade to 4.1 right? Im currently on 3.3. I tried the below code: $var(i)=0; while($(hdr(Diversion)[$var(i)]) != $null ) { $avp(s:divhdr) = $(hdr(Diversion)[$var(i)]); avp_subst("$avp(s:divhdr)", "/.*sip:(.*)(@.*)/\1/"); xlog("L_WARN", "$avp(s:divhdr)"); if (!is_user_in("$avp(s:divhdr)", "7")) { sl_send_reply("403", "NOT ALLOWED"); exit; }; $var(i) = $var(i) +1; } However, it seems like group module cant parse the output 313 as seen below: Apr 10 13:16:43 SipProxy-Test /usr/local/sbin/kamailio[7471]: WARNING: <script>: 313 Apr 10 13:16:43 SipProxy-Test /usr/local/sbin/kamailio[7471]: ERROR: group [group.c:114]: failed to parse URI <313> Apr 10 13:16:43 SipProxy-Test /usr/local/sbin/kamailio[7471]: ERROR: group [group.c:158]: failed to get username@domain A bigger issue is that a certain client is sending more than one diversion header with different format as seen below: Diversion: <tel:22030009>;reason=no-answer;screen=no;privacy=off Diversion: "Solonas A" <sip:16@10.10.10.22>;reason=unconditional So in this case i cant really know how to extract the diversion number using a static substitution. Is there a way to adapt to different formats to extract the diversion number?

too many hope SIP issue with "Route" header in proxy server
by Youngjin Park 10 Apr '13

10 Apr '13

Hi, I have a problem with "Route" header in my proxy server. Incoming invite has "Route" header with the IP of the proxy. So, the proxied invite from proxy server is looping back to the proxy server. I believe that "Route" cannot be removed or deleted because it is one of system header. Is there any way to avoid this loop? Thanks Young

Operator !~
by Jon Bonilla 09 Apr '13

09 Apr '13

Hi all I was checking for an operator not matching regular expression. Acording to the doc we have =~ and !~ for matching and not matching. http://www.kamailio.org/wiki/cookbooks/3.3.x/core#script_statements I tried this one: if(!is_domain_local("$rd") && $rd !~ "^.+\.local$") Resulting on these errors: root@sp1:~# /etc/init.d/kamailio-proxy restart Not executing command for kamailio-proxy: invalid configuration file! -e 0(1813) : <core> [cfg.y:3549]: parse error in config file /etc/kamailio/proxy/proxy.cfg, line 1067, column 36: syntax error 0(1813) : <core> [cfg.y:3549]: parse error in config file /etc/kamailio/proxy/proxy.cfg, line 1067, column 52: bad expression 0(1813) : <core> [cfg.y:3549]: parse error in config file /etc/kamailio/proxy/proxy.cfg, line 1067, column 52: bad command 0(1813) : <core> [cfg.y:3549]: parse error in config file /etc/kamailio/proxy/proxy.cfg, line 1068, column 2: bad command 0(1813) : <core> [cfg.y:3546]: parse error in config file /etc/kamailio/proxy/proxy.cfg, line 1083, column 2-21: syntax error 0(1813) : <core> [cfg.y:3546]: parse error in config file /etc/kamailio/proxy/proxy.cfg, line 1083, column 2-21: ERROR: bad config file (6 errors) while this one: if(!(is_domain_local("$rd") || $rd =~ "^.+\.local$")) Works perfectly fine. Am I wrong with the usage of !~ operator? cheers, Jon

Contact header from linphone too long to delete
by Ross Kusler 09 Apr '13

09 Apr '13

Hello, We noticed an issue with a bunch of stale entries in the mysql location table recently - all for the same user. It turns out that if you install linphone 2.0.2 on an iOS device (other versions/platforms might also be affected) with the transport mode set to TCP and the 'Push Notification' feature enabled, the client generates very long contact (258+ character) headers. The contact column in the location table is varchar(255), anything longer than this automatically gets truncated upon insert. When the entry later expires and usrloc tries to remove it, it generates a delete query that matches on the entire contact value and not the truncated version. This causes the delete query to fail and the usrloc record gets left behind in the location table. The (truncated) contact header value from the database: sip:22448462@98.248.37.244:52008;transport=tcp;app-id=org.linphone.phone.pro d;pn-type=apple;pn-tok=AA31DC9642E76E7D7DA8A0E419B210E1A00E8DF43A7A77C8CD295 5291E1BAC85;pn-msg-str=IM_MSG;pn-call-str=IC_MSG;pn-call-snd=ring.caf;pn-msg -snd=msg.caf;line=932257155 The failed delete query:. delete from location where username='XXXXXXXX' AND contact='sip:XXXXXXXX@11.22.333. 44:52000;transport=tcp;app-id=org.linphone.phone.prod;pn-type=apple;pn-tok=A A31DC9642E76E7D7DA8A0E419B210E1A00E8DF43A7A77C8CD2955291E1BAC85;pn-msg-str=I M_MSG;pn-call-str=IC_MSG;pn-call-snd=ring.caf;pn-msg-snd=msg.caf;line=932257 155f64767' AND callid='1962857815'; What do you all think the best solution here is? My intuition is to simply increase the size of this column. If this is the right approach then it probably also makes sense to update the .sql file for new installs. Thoughts? Thank you, Ross

Diversion header authentication
by phillman25 09 Apr '13

Dear List I am currently using the group module to authenticate inbound calls using the From header using the below code: if (!is_user_in("From", "1")) { sl_send_reply("403", "NOT ALLOWED"); exit; }; }; I want to now authenticate the Diversion header, when the call is diverted, the same way as above using the group module how could i proceed with this? thanking you in advance Phillip

how to configure presence module with websocket
by אורן אברהם 09 Apr '13

09 Apr '13

hello. I am tring to SUBSCRIBE for presence status of a user on my kamailio server using the sipMl5 (over websockets) but kamailio failes. (more exactly the handle_subscribe failes.) I was told previusly by peter dunkly that it is not a bug, just a configuration problem. I am quoting his answer: "This is a configuration problem not a bug in the software. SUBSCRIBEs are dialog forming requests and NOTIFYs (in this scenario) are in-dialog requests. As such you need to use force_rport(), add_contact_alias(), and handle_ruri_alias() with presence dialogs in the same way you do with media session dialogs." How can i acheve this ? thanks in advance...
