How to remove attribute from SDP ?
by Vitaliy Aleksandrov 14 May '14

14 May '14

Hello list, Can anybody suggest the way to remove a line/attribute from SDP that matches some pattern (regexp), some kind of "grep -v" for SDP ? I'm trying to remove unnecessary ICE candidates from the SDP body and only thing I know is the IP address of the candidate I need to remove. I was trying to use avp_subst() + set_body() or subst_body() but didn't get valid SDP. kamailio-3.2.4.

reg_fetch_contacts for multiple devices registered
by Jonathan Hunter 14 May '14

14 May '14

Hi Guys, I was wondering if anyone could help? I am currently using reg_fetch_contacts to manipulate signaling based on the user agent device being used, therefore I use the result of; if(reg_fetch_contacts("location", "$ru", "callee")){ xlog("callee=>user_agent $ulc(callee=>user_agent)\n");} I then use $ulc(callee=>user_agent) to make routing decisions. This seems to only return the user-agent device being used for the first registration at that AOR, as I have two devices registered, a Cisco, and a jitsi client, and it only returns the user_agent of the jitsi client I registered first. Is it possible to return the user agents of all the devices registered against an AOR so I can manage decisions accordingly? Many thanks Jon

Presence dialoginfo - initial empty NOTIFY
by Ewgeny 14 May '14

14 May '14

Hello list, we're using kamailio presence for BLF functionality, that means lamps on the phone are green when phone is IDLE, blinking RED when - ringing and RED when busy. The problem is - when the phone send SUBSCRIBE first time - presence answers with empty NOTIFY (with no XML info), and lamps on the phone (for some extension) are OFF. The laps will became green only after first call to that extension. How to make non empty first NOTIFY message ? My config: #!ifdef WITH_PRESENCE # ----- presence params ----- modparam("presence", "db_url", DBURL) modparam("presence", "subs_db_mode", 2) modparam("presence", "server_address", SBC_IPADDR) modparam("presence", "max_expires", 60) modparam("presence", "db_update_period", 200) # ----- presence_xml params ----- modparam("presence_xml", "db_url", DBURL) modparam("presence_xml", "force_active", 1) modparam("presence_xml", "integrated_xcap_server", 0) modparam("presence_dialoginfo", "force_single_dialog", 1) #dialog need as dependence modparam("dialog", "dlg_flag", 4) modparam("dialog", "db_mode", 0) #!endif the kamailio 3.3.4 example of initial empty NOTIFY: NOTIFY sip:user_A@192.168.4.2:5064 SIP/2.0 Via: SIP/2.0/UDP xx.xx.xx.xx;branch=z9hG4bK693a.4fc432a84fe66cca11790dc1db4d520b.0 Via: SIP/2.0/UDP 10.10.10.10;rport=5060;branch=z9hG4bK693a.e25d1976.0 To: sip:user_A@xx.xx.xx.xx;tag=1632547193 From: sip:user_A@xx.xx.xx.xx;tag=40b780c8a91f5771f2f8fb63063e8dc6-f960 CSeq: 57 NOTIFY Call-ID: 997810293-5064-30(a)BJC.BGI.E.C Route: <sip:10.10.11.11;r2=on;lr=on;ftag=1632547193>, <sip:xx.xx.xx.xx;r2=on;lr=on;ftag=1632547193> Content-Length: 0 User-Agent: kamailio (3.3.4 (x86_64/linux)) Max-Forwards: 69 Event: dialog Contact: <sip:10.10.10.10:5060> Subscription-State: active;expires=60 example of NOTIFY with XML info: NOTIFY sip:user_A@12.12.12.12:1049 SIP/2.0 Via: SIP/2.0/UDP 10.10.10.10;branch=z9hG4bKb7e2.4fd3e262.0 To: sip:user_A@xx.xx.xx.xx;tag=2032642966 From: sip:user_B@xx.xx.xx.xx;tag=40b780c8a91f5771f2f8fb63063e8dc6-a5e9 CSeq: 195 NOTIFY Call-ID: 734484242-5064-35(a)BJC.BGI.E.C Route: <sip:10.10.11.11;r2=on;lr=on;ftag=2032642966>, <sip:xx.xx.xx.xx;r2=on;lr=on;ftag=2032642966> Content-Length: 327 User-Agent: kamailio (3.3.4 (x86_64/linux)) Max-Forwards: 70 Event: dialog Contact: <sip:xx.xx.xx.xx:5060> Subscription-State: active;expires=60 Content-Type: application/dialog-info+xml <?xml version="1.0"?> <dialog-info xmlns="urn:ietf:params:xml:ns:dialog-info" version="00000000000" state="full" entity="user_B(a)10.10.10.10"> <dialog id="fd72b08c-5603-1232-f192-005056954c8a" call-id="fd72b08c-5603-1232-f192-005056954c8a" direction="recipient"> <state>terminated</state> </dialog> </dialog-info>

How to reply an INVITE with 403
by varun pratapsingh 14 May '14

14 May '14

Hi All, I want to handle a special case in the Kamailio 4.1.3. When I receive INVITE from some UAC I wanto reply it with 403 message. I am using the Kamailio in Proxy mode when the INVITE comes I want to reply it with 403 and do not want to send this INVITE to SIP Server. I expored the Kamailio source code and found that fucntion receive_msg() in file receive.c receives all the SIP messages. I am able to parse the SIP INVITE from such UACs but how to reply them with 403 SIP Code. I am unable to use the t_reply("403","Forbidden") here in this function/file. Also in this function finally the forward_reply(msg); is called which sends the INVITE to the Sip Server. But I dont want to send anything to SIP Server in this case but want to reply the UAC with 403. Can you please guide me how to do and where to do this. I am new to kamailio. Please help. Regards Varun

Issue in Multi Domain Environment
by aawaise 14 May '14

14 May '14

I have deployed two kamailio servers with independent domain names, BOTH sharing the same database. When an "INVITE" packet approaches one server from a user. As per my understanding it checks "Location Table" (containing online users) to find about status (online or not) of called user. If user is present in LOCATION TABLE, kamailio server sends INVITE to callee else it disconnects the call. In LOCATION TABLE, DOMAIN NAME is also mentioned along with user name, I want to extract that domain name of callee user from LOCATION TABLE with every INVITE packet. What variable stores this information ?? How can it be extracted ?? I have tried using "$du". It consumes RURI and gives domain name, it picks domain name from invite packet, which is not required here. Requirement is to pick domain name from LOCATION TABLE, by which user is logged into the system. (In multidomain setup, they both can be different). I have also tried "$td", they also pick domain name from INVITE packet header. I want to print (i.e xlog) value of domain from the LOCATION TABLE. And it is bothering for quite a few days now. Any help will be much appreciated. Thanks. Regards, Aawaise. -- View this message in context: http://sip-router.1086192.n5.nabble.com/Issue-in-Multi-Domain-Environment-t… Sent from the Users mailing list archive at Nabble.com.

SHM error after few days...
by Krishna Kurapati 13 May '14

Hi, After few days of running kamailio (I am using TLS for client), suddenly I see that the connections are being dropped. When I restart kamailio, I see following errors: Stopping kamailio: [FAILED] Not starting : invalid configuration file! 0(20563) : <core> [mem/shm_mem.c:168]: shm_getmem(): ERROR: shm_mem_init: could not attach shared memory segment: Cannot allocate memory 0(20563) : <core> [mem/mem.c:125]: init_shm_mallocs(): could not initialize shared memory pool, exiting...

It started fine initially. However, after I noticed connection drops, I see the above issue. THen I reduced shared memory to 2048M and it started fine. I am under the impression that shared memory is just a filed I/O mapped which can be several hundred gigs. I looked at my filesystem. It looks fine df Filesystem 1K-blocks Used Available Use% Mounted on /dev/sda3 958788080 200734800 709349640 23% / tmpfs 3975996 0 3975996 0% /dev/shm /dev/sda1 495844 37498 432746 8% /boot What could be wrong here? Any help greatly appreciated. Krish Kurapati

RTP ports
by Neville D'Souza 13 May '14

13 May '14

HI , How do I find out which udp ports my kamailio server is using. In Kamailio.cfg I am using socket like below. #!ifdef WITH_NAT # ----- rtpproxy params ----- #modparam("rtpproxy", "rtpproxy_sock", "udp:127.0.0.1:7722") modparam("rtpproxy", "rtpproxy_sock", "unix:/var/run/rtpproxy/rtpproxy.sock") I need to know the exact port range to open ports on my firewall if necessary. Our Kamailio server works just fine outside our network, but when I try to make calls through linphone client using a android device inside our network, as soon as I pick up the call it gets disconnected. The same thing happens when someone from outside tries to call in to our network. Funny part is when I use a desktop client like jitsi the calls between 2 users in the network or with someone outside the network work fine. I am guessing the rtp traffic is being dropped by the firewall when using linphone android client. It was working fine previously but after a firewall OS update it stopped working.
