Kamailio presence (NAT, XCAP)
by Radu Vatav 18 Jul '14

18 Jul '14

Hello, I'm just trying to use SIP as a replacement for Skype, nothing more than that. All is working except of presence. Using Jitsi 2.4.4997 (Windows x64) from home behind NAT and kamailio 4.1.4+wheezy on a rented server somewhere. My biggest problem is that I don't know exactly how it is supposed to work. Ok, this is what I understood so far: the clients connect via SIP to the server and can call each other, but for some reason the server can't notify them via SIP of presence changes when they are behind NAT. So the clients also connect to the built in xcap-server, register themselves as presence "watchers" and the xcap-server notifies them via udp/tcp of presence changes of the other users which are watched. All is very nice but it's not working and I don't know where to look for the problem. Which are exactly the steps in communication and what data exactly is there sent which way (when working correctly, which it doesn't) - no clue. I somehow put the configuration together from the 2-3 examples I found on the internet, I don't know if it is ok to attach something to this email, so here it is: https://vatav.cc/kam/kam_cfg.7z Here is the network activity on the server: https://vatav.cc/kam/kam_ngrep.7z So me ("radu") and "alice" are home behind the NAT, one is online and wants to see how the other one goes online and offline. I don't know what exactly to look for, but it doesn't look to me like there is anything sent to one user when the other one goes on-/off-line (there is a lot of "proxy authentication required" which drives me nuts, again I don't know if this is correct or not; Jitsi seems to be connected to the XCAP server, if I type in a wrong address for "XCAP server" Jitsi complains it can't connect). Some other things: - "kamctl online" shows almost real-time who is logged-in, so this works - siremis shows a bunch of users in "watchers list", but none in "active watchers list" - actually when a user goes online it contains the contacts of that user, but only briefly, when I refresh the view, the list is empty again. I don't know if this is how it is supposed to work, anyway, Jitsi doesn't show any change of the status of the user who changed status at all. Any help would be appreciated. It's sad something this simple as I need (basic Skype replacement) is so difficult to get working. Maybe this is why there is relatively low interest in SIP and everybody stays with MS/Google/... because "there isn't something else". Best regards, Radu Vatav

Groups in Kamailio vs Freeswitch
by Peter Villeneuve 18 Jul '14

18 Jul '14

Hi guys, I'm designing a new service for a client and I was wondering what your opinion is of the 2 options I'm considering to separate users on the server. Basically I want to create closed groups where each user can only call and receive calls from members of the same group (single domain install). Initially I was thinking of just forwarding all the invites to FS and using the dialplan to enforce this segregation, but now I realize there is a groups module in kamailio too. Which 2 courses of action do people recommend? I'm more familiar with FS than Kamailio, so it would be easier for me to just forward everything to FS, although that will be more expensive and probably unnecessary if I could do it all in Kamailio with Siremis. Would kamailio's group module do the trick? Are there any tutorials out there I can follow? Cheers, Peter

Re: [SR-Users] how to remove non-digits using dp_translate
by Daniel-Constantin Mierla 18 Jul '14

18 Jul '14

Hmm, I see there is none inside dialplan for the moment. The option would be to do it in config file with a function from textops. Also, check if regex module is a good alternative for you: - http://kamailio.org/docs/modules/stable/modules/regex.html Cheers, Daniel On 16/07/14 16:50, Henry Fernandes wrote: > Can anyone show me how to use the regexp global flag using dp_translate? > -H > > From: Henry Fernandes <henry(a)usinternet.com <mailto:henry@usinternet.com>> > Reply-To: "Kamailio (SER) - Users Mailing List" > <sr-users(a)lists.sip-router.org <mailto:sr-users@lists.sip-router.org>> > Date: Friday, 11 July, 2014 4:18 PM > To: <miconda(a)gmail.com <mailto:miconda@gmail.com>>, "Kamailio (SER) - > Users Mailing List" <sr-users(a)lists.sip-router.org > <mailto:sr-users@lists.sip-router.org>> > Subject: Re: [SR-Users] how to remove non-digits using dp_translate > > I don't know how to apply the global flag in Kamailio.

Some of the calls drops after 15 minutes + some seconds
by Andras FOGARASI 18 Jul '14

18 Jul '14

Hi, I have a simple kamailio install (2 servers, using location service and a failover node with dispatcher, STUN, clients behind different NATs), without rtpproxy, only peer-to-peer RTP and TURN server if the connection is really messy (it's not relevant here). Signaling is over TLS. Both of the clients are behind NAT. Basically everything works, but some of the calls are dropped after 15 minutes and some seconds, for me it seems the RTP connection is dropped but not sure. I cannot find find out wether it's a kamailio problem or client/NAT problem. Has anyone idea what is going on? Thanks, Andras

Really need help on kamailio-snmpstats module
by Allen Zhang 17 Jul '14

17 Jul '14

Hi This is a re-post. I'm desperate. What I'm trying to do: Use rpmbuild to build kamailio rpms from source code. We made a lot of changes in the kamailio code. I can't use the rpms from the build service. The plan is to push these changes to kamailio but that's not done, yet. The problem is when I try to install kamailio-snmpstats module from the rpm built, it reports error: Error: Package: kamailio-snmpstats-4.0.0-0.el6.x86_64 (company_name) Requires: net-snmp-agent-libs I've installed net-snmp on the build machine and the machine that needs to install kamailio-snmpstats. I have tried to use the kamailio.spec file from kamailio build server but it didn't solve the problem. Can anyone help, please? Regards, Allen

Condition Statements - How many levels
by Joel White 16 Jul '14

16 Jul '14

I was wondering how many levels deep in conditional _if_ _else_ statements can go. I need to create a statement that has 4 possible outcomes and need to know if this is possible. I have two variables I want one thing to happen if only the first variable is present Another if only the second variable is present Yet another if they are both present And a fail over if None of the variables are present I do see that is can be done with 3 conditions using _if_ _if else_ _else_ how can I accomplish 4 conditional statements? Thank you in advance Joel
