Hello, it is now one month till the 10 years SER event in Berlin. I am thinking to collect few statistics about usage of SER-based code at this moment (SER, OpenSER, Kamailio, OpenIMSCore ...) and present them during the conference and publish on the web. Everything is going to be like a combined report, not individual listing. Therefore, if you want to participate, your name or company won't be mentioned. Here are the stats I thought of: - type of usage: production, evaluation (testing), research - number of subscribers (phone lines) - percentage of phones behind NAT - number of calls per month - number of call minutes per month I am not looking for exact numbers, but rough estimation (e.g., about 10 000 phone lines, ...). Of course, some of the metrics don't apply always (e.g., if you do termination routed through SIP server, you don't have subscribers, but just calls traffic). Those doing deployments, can make one summary of statistics for all instances. You may send other statistics you think they worth publishing. Again, this is voluntary, naming is not required. I hope only those giving real number will write back -- I will try anyhow to figure out if someone is just dumping fantasy numbers. If privacy is really a big concern, from case to case, everything can be done under NDA.

Celebrating 10 years SER SIP Router in Vienna: 8th September 2011

by Klaus Darilion

Hi! If you haven't noticed yet, SER (the mother of the SIP proxy projects Openser, Kamailio, sip-router, opensips, ....) is celebrating their 10th year. There will be a main event happening in Berlin (http://sip-router.org/10-years-ser/). For those who can not travel to this event, there will be some smaller events around the world. In Vienna, this will happen on the 8th September at 7pm in the evening, organized by Andreas Granig and myself. We do not plan to have a big event with speaker, it is just an informal come together to meet with other SER-interested[1] guys, having some techie talks, maybe getting some business contacts and drinking some beers. Drinks will be sponsored by http://www.ipcom.at/ and http://www.sipwise.com/. The event will happen in the city center of Vienna. The location is not fixed yet, it depends on how many people are going to attend. Thus, please let us know if you going to attend (send us a short e-mail) and spread this e-mail to interested people you know. Cheers Andreas and Klaus [1] User's of all SER-flavors are welcome

Kamailio setup help - needed in Hamburg / Germany

by Rene Bormann

Hello SR List, our background is classic telephony with E1 interfaces, active telephony-cards etc. We now got our telephone-plattform transformed for SIP, but all behind a firewall. Actually we receive calls from some carriers throu the firewall on our Asterisk, which has E1 links to the IVR -Plattform. Now we want to eliminate Asterisk as kinda internal PSTN gateway and direcly route the calls throu Kamailio to our IVR services. So we thought, hey Kamailio can't be that complicated to setup, but now we have to admit - that we are kinda "LOST". We are located in Hamburg / Germany and need HELP. Is on this list anyboy - who can help us, maybe from around Hamburg? Get us on the kamailio train or maybe help us on a continous bases? Thanks from Hamburg, René

Kamailio 3.1.1 snmpstat help!!

by Stephen Dodge (Bistech)

Hello, I am having difficulty running the snmpstats module. We are running CentOS 5.6 and Kamailio version 3.1.1 (i386/linux). I've tried a fresh install of Kamailio, installing net-snmp from source but I can't seem to get it running - I've seen a couple of posts regarding the issue but nothing seems to work for us!! The issue I get when I start Kamailio is: 0(27523) ERROR: <core> [sr_module.c:523]: ERROR: load_module: could not open module </usr/local/lib/kamailio/modules_k/snmpstats.so>: /usr/lib/libnetsnmpagent.so.10: undefined symbol: hosts_ctl Any help would be much appreciated. Also, if anyone has any suggestions on how best to get either Solarwinds or PRTG to monitor our Kamailio servers that would be good. Thanks.

registered("location") not working

by Skyler

Hi all, I am attempting to only reply to NOTIFY when the request is originating from a user/device that is authenticated on kamailio already. There are 2 ways I've tried (below) but neither will work. Any idea on what I am doing wrong or suggestions on how to do it right? TIA, Skyler if(is_method("NOTIFY") && is_registered("location")) { route(ROUTE_NOTIFY); } OR .... if(is_method("NOTIFY")) { # We only reply OK if coming from authenticated users or trusted peers if(!registered("location") || !from_any_gw("$avp(s:ip)")) { sl_send_reply("503", "Service Unavailable"); exit; } xlog("L_INFO", "Friendly Peer Poke - M=$rm F=$fu R=$ru\n"); sl_send_reply("200", "OK"); exit; }

Re: [SR-Users] Kamailio as simple SIP proxy between client and SIP server.

by Edson - Lists

Hi, Henrik... Please, never, ever, forget to copy the list in a thread initiated there... other may be "curious" on it... ;) About your configuration, it seems that you just need a 'simple forward' server. It's very simple to accomplish... Make a simple forward configuration script (you can start with the provided one and cut all registration and whistles). Just be aware of all security issues binded to this choice. Ok... you still can load any of the control modules (pike, p.ex.) and have some prevention, but even so it's not your best choice. Edson.

Kamailio as simple SIP proxy between client and SIP server.

by Henrik Aagaard Sørensen

This is my current setup, which works: SIP client <-> SIP server. As I've currently moved to another country I would like to be able to do the following setup: SIP client <-> Kamailio SIP proxy <-> SIP server. As the SIP server only accept packets from specific IP's. Is it possible? I've managed to setup a simple Kamailio installation on my server, which does have a valid IP for the SIP server. With the Kamailio installation I've also enabled NAT with RTPProxy. My problem is now, that the Kamailio installation doesn't work as a simple proxy, but actually takes registrations etc. and acts as a "full-blown" SIP server. It should only take SIP messages and transfer them between clients and server. Any ideas?
