How to thoroughly test a proxy?
by Steve Davies 22 Aug '13

22 Aug '13

Hi Kamailians, Can anyone on the list point me at a list of call flow scenarios I should consider and test to be confident my proxy setup works properly. I'm not looking at the moment for some sort of SIPit torture test, just a sensible set of scenarios. This is for my client side "outbound sip/rtp proxy" I so far have thought about: Ordinary outbound and inbound calls Holding / unholding "Blind" transfers "Attended" transfers mid-call reINVITEs (session timers?)

Hi All, I'm just trying to setup the TLS on the last Kamailio v4.0.3 on Fedora 18 64bits. Kamailio doesn't start and terminate with the error below: loading modules under /usr/local/lib/kamailio/modules_k/:/usr/lib64/kamailio/modules/ 0(1676) ERROR: tls [tls_init.c:471]: tls_pre_init(): Unable to set the memory allocation functions 0(1676) ERROR: <core> [sr_module.c:600]: load_module(): ERROR: load_module: /usr/lib64/kamailio/modules/tls.so: mod_register failed 0(1676) : <core> … [View More]

Unable to call Extension in Asterisk Server & Vice Versa
by Nishar M.H 22 Aug '13

22 Aug '13

Hi All, I have created a Two VMs for Asterisk & Kamailio. Asterisk IP : 192.168.20.196 Kamailio IP : 192.168.20.208 I have installed both successfully. I have created trunk between two and successfully started kamailio. What i am looking for : 1) Asterisk as media server and Kamailio as SIP Server. 2) Call from Asterisk to Kamailio and vice versa. 3) Enable Outbound call for Kamailio User through Asterisk Server. 4) Inbound call from outside through Asterisk to Kamailio Users. The … [View More]issues i am facing here is : 1) Unable to call Internally. Kamailio SIP to SIP. If i tried to call from 1000 to 1001, "No route to destination. 2) Unable to call from Asterisk to Kamailio and vice versa. Here is the log below: /var/log# tail /var/log/syslog Aug 21 09:37:36 kamailio-VirtualBox kamailio: INFO: <core> [tcp_main.c:4846]: init_tcp: using epoll_lt as the io watch method (auto detected) Aug 21 09:37:36 kamailio-VirtualBox /usr/local/sbin/kamailio[17495]: INFO: rr [../outbound/api.h:49]: Failed to import bind_ob Aug 21 09:37:36 kamailio-VirtualBox /usr/local/sbin/kamailio[17495]: INFO: rr [rr_mod.c:159]: outbound module not available Aug 21 09:37:36 kamailio-VirtualBox /usr/local/sbin/kamailio[17495]: INFO: usrloc [hslot.c:53]: locks array size 512 Aug 21 09:37:36 kamailio-VirtualBox /usr/local/sbin/kamailio[17495]: INFO: <core> [udp_server.c:179]: INFO: udp_init: SO_RCVBUF is initially 163840 Aug 21 09:37:36 kamailio-VirtualBox /usr/local/sbin/kamailio[17495]: INFO: <core> [udp_server.c:230]: INFO: udp_init: SO_RCVBUF is finally 262142 Aug 21 09:37:36 kamailio-VirtualBox /usr/local/sbin/kamailio[17495]: INFO: <core> [udp_server.c:179]: INFO: udp_init: SO_RCVBUF is initially 163840 Aug 21 09:37:36 kamailio-VirtualBox /usr/local/sbin/kamailio[17495]: INFO: <core> [udp_server.c:230]: INFO: udp_init: SO_RCVBUF is finally 262142 Aug 21 09:37:36 kamailio-VirtualBox /usr/local/sbin/kamailio[17507]: INFO: ctl [io_listener.c:225]: io_listen_loop: using epoll_lt io watch method (config) Aug 21 09:39:59 kamailio-VirtualBox /usr/local/sbin/kamailio[17504]: NOTICE: acc [acc.c:275]: ACC: call missed: timestamp=1377063599;method=INVITE;from_tag=ea6d986d;to_tag=;call_id=ZDZhMzkxN2RjZjhhYmJhMmJiNTM0OTRlYzA3NzJkMTA.;code=408;reason=Request Timeout;src_user=1000;src_domain=192.168.20.208;src_ip=192.168.20.186;dst_ouser=1000;dst_user=1000;dst_domain=192.168.20.186 One more thing i have to ask is : 1) Is there any command to check Kamailio has a trunk with Asterisk PBX server ?

Subscribe to a common resource list
by Yufei Tao 22 Aug '13

22 Aug '13

Hi I'm trying to work with RLS. Is there a way of allowing user1 and user2 to both subscribe to a common group of contacts, group.common? Seems that each user can only subscribe to its own resource list and won't be able to subscribe to other user's resource list. For example, both user1 and user2's RLS services documents contain resource-list pointing to group1's resource list, like this: <?xml version='1.0' encoding='UTF-8'?> <rls-services xmlns:rl="urn:ietf:params:xml:ns:resource-… [View More]

options_reply()
by Alex Balashov 22 Aug '13

22 Aug '13

Hello, The options_reply() function does not answer OPTIONS pings that contain a username in the request URI. To its credit, the documentation does say that, too: http://kamailio.org/docs/modules/4.0.x/modules/siputils.html#idp131056 The question is: why not? I do not see anything in RFC 3261 Section 11.1 ("Construction of an OPTIONS Request") that seems to rule out an OPTIONS request with a user part: http://tools.ietf.org/html/rfc3261#section-11.1 Quite a few UAs out there,… [View More]

I've installed Kamailio v4.0.x packages on my Ubuntu 12.04.1 LTS I would like to configure LCR and CARRIERROUTE modules but I don't find sufficient guide to do it properly. Though i am looking to http://kamailio.org/docs/modules/4.0.x/modules/ for the said modules but it's a bit scattered for me. Can anyone give me resources or guide where I can found : - required modparam for LCR and CARRIERROUTE - SQL examples datas for both modules - example of route logic using both … [View More]

Presence: Get number of active_watchers
by Jan Gaida 21 Aug '13

21 Aug '13

Hello, I need to obtain the number of subscribed watchers for a given presentity-uri. I can get it with a SQL Query like "select count(*) from kamailio.active_watchers where presentity_uri = 'test@domain';". But I think there should be a way to get it from within the configuration script.

Enterprise Presence Information
by Ryan C Ash 21 Aug '13

21 Aug '13

Good day, Quick question for the group. I am looking at choosing an open source product to potentially use for enterprise presence. The solution would be on the receiving end of SIP NOTIFY messages from Cisco CUCM clusters. This is a very large enterprise environment. I am hoping to stay on the LAMP stack which leads me a bit away from Mobicents. At this time we aren't looking for much else other than designing an highly available solution that can act as the receiving end of these SIP … [View More]

Is Kamailio's presence modules support pidf-diff+xml format?
by Evgeny Vinnik 21 Aug '13

Is Kamailio's presence module support pidf-diff+xml (RFC 5262 aka Partial PIDF) format? Did anyone tried to implement parsing of such format? It just I have an issue with an RCS client, which updates presence information in the Partial PIDF format.

multihomed Kamailio and enable_double_rr
by Steve Davies 21 Aug '13

21 Aug '13

Hi, I'm having a problem with routing of BYEs in my multi homed Kamailio. My setup is a phone on 172.16.230.1, talking to Kamailio on 172.16.230.128. On the "outside" Kamailio uses 10.64.5.16 and its talking to 41.221.230.60 I'm using the stock Kamailio 4.0.3 kamailio.cfg, with: WITH_NAT defined mhomed=1 Little change in NATMANAGE to do the rtpproxy_manage with ie or ei as appropriate, coming from my previous post and the response from Alex. Here's the invite from the phone: U 172.16.… [View More]230.1:3694 -> 172.16.230.128:5060 INVITE sip:7171001@vc2.connection-telecom.com;transport=udp SIP/2.0.

So that behaviour seems OK. The call does get correctly established and rtpproxy is correctly setup and audio passes in both directions. But when the BYE is sent (from the outside), though, things go wrong: Here's what arrives from upstream. Route: has the two entries per the RR that was sent. U 41.221.230.60:5060 -> 10.64.5.16:5060 BYE sip:2686959@10.64.5.16:5060;transport=udp SIP/2.0. Record-Route: <sip:41.221.230.60;lr=on;ftag=as70703d1c>.

So Kamailio peels off the first route and then sends the BYE actually to itself. With an oddly formed blank Route: header. Tracing through the kamailio.cfg the BYE is processed in WITHINDLG - loose_route() succeeds It logs that 172.16.230.128 "is loose router".

When Kamailio receives the BYE from itself it sends a 404 Not here. Which is forwarded back upstream. This 404 Not here is generated in WITHINDLG too; looks like loose_route() fails (which makes sense since there is nothing in the Route header), and in that case WINTHINDLG only has code for dealing with SUBSCRIBE and ACK.

I tried with enable_double_rr as 0 and that did send only one Record-Route with the relayed INVITE, but the record route uses the inside address of the proxy and so we never even receive the BYE from the upstream system in that case. I'm kinda lost about where this is going wrong - so pointers would be welcome! Thanks, Steve [View Less]
