CDRs for failed calls
by Mickael Marrache 28 Jan '15

28 Jan '15

Hi, Is there a way to write CDRs for failed calls? I tried calling the acc_db_request command from my script, but it inserts a transaction log not a CDR. Thanks, Mickael

Hi, Is it possible to save user location data in a MongoDB database? If not, are you guys using p_usrloc in your projects? Can you please give me some feedback? Thanks, Mickael

How to run Kamailio as a stateful proxy
by Thomas Bäumer 28 Jan '15

28 Jan '15

Hello all, we are are a small network-provider and selling internet via FTTC and FTTH. To complete the portfolio we also sell telephony via a rented ClassV Service with provisioning API, but its not our system and not in our network. To get more informations about Registration-Status and calls I have now installed a kamailio as a statefull proxy between the subscriber and the softwitch: |----------| |subscriber|\ --------- |----------| \ /| Mobile| \ -------------- / --------- |----------| \ ------------ | Class V | / -------- |subscriber|---------| Kamailio |--------| Softswitch |-------| PSTN | |----------| / ------------ | | \ -------- / -------------- \ --------- |----------| / \| World | |subscriber|/ --------- |----------| I am really new in kamailio, so I just use the configuration named "Edge Proxy Configuration" shown in the documentation to the outbound module, see http://kamailio.org/docs/modules/4.2.x/modules/outbound.html example 1.1. We dont need NAT and STUN because all our subscribers get official IPv4 addresses. Outgoing calls (subscriber -> PSTN) are working fine, all SIP messages pass the Kamailio Proxy. But incoming Calls (World -> subscriber) miss the proxy and will be routed directly from the Softwitch to the subscriber. I think because of the Contact-Header in the subscriber REGISTER: Contact: <sip:49xxxxxxyyyyyy@134.xx.yy.zz;uniq=E41120B46C92D3818E72B> This is the IP of the subscriber FritzBox. So I just added some lines to replace the Contact-Header in the REGISTER to get all incoming Calls from the Softswitch to the Kamailio: if (is_method("REGISTER")) { if (src_ip==CUSTOMER_NET) { remove_hf("Route"); add_path(); $du = "sip:REGISTRAR_IP:REGISTRAR_PORT"; if ($ct != $null) { subst('/^Contact:(.*)@[a-zA-Z0-9.]+(.*)$/Contact:\1@KAMAILIO_IP\2/ig'); } } } and now the Contact-Header looks better: Contact: <sip:49xxxxxxyyyyyy@KAMAILIO_IP;uniq=E41120B46C92D3818E72B> Now the subscriber is registered on the Softswitch with the IP from the Kamailio. And now the Kamailio get the incoming Call, but directly route it back to the Softwitch and the call failed. Now my questions: - Is the "Edge Proxy Configuration" right for this setup? - How the Kamailio keep all registered IPs and Lines to route an incoming Call to the right subscriber? - Why the Kamailio route an incoming call directly back to the Softswitch? Thanks a lot. Regards Thomas

Can't start Kamailio with both db_postgres and tls
by Øyvind Kolbu 28 Jan '15

28 Jan '15

Hi, I'm trying to add tls to our services, but seem hindered by "something". When enabling the tls module it seems to turn off the SSL setting in postgresql, and since we require SSL on our postgres servers Kamailio can't connect and it fails to start. If I disable WITH_TLS it will start. If I comment out the sqlops modparam it will also start.

Trouble getting start time / call duration from dialog module
by Will Ferrer 28 Jan '15

28 Jan '15

Hi All I am in need of being able to see what the duration of the call was at the time of hang out. I tried turning on the dialog module, but the result is that the values I need are either null or always show as zero. I tried to follow the suggestions in the thread about this here: http://lists.sip-router.org/pipermail/sr-users/2010-October/065889.html In the end my config looks like this: loadmodule "dialog.so" ... modparam("dialog", "dlg_flag", 4) modparam("dialog", "dlg_match_mode", 1) ... request_route { if (is_method("INVITE") && (! has_totag() ) ) { dlg_manage(); } if (is_method("BYE")) { $var(elapsed) = ( $TV(s) - $dlg(start_ts) ); xlog ("L_INFO", "request_route DIALOG TEST: Completed $dlg(from_uri) to $dlg(to_uri), elapsed: $var(elapsed), now seconds: $TV(s), dlg start time: $dlg(start_ts), DLG_lifetime: $DLG_lifetime"); } .... Note that I put at the top of the request route just for testing purposes The result I get in the log is this: INFO: <script>: request_route DIALOG TEST: Completed sip:willf1976Test@develop-sbc.switchsoft.com to sip:+18054515526@develop-sbc.switchsoft.com, elapsed: 1421305210, now seconds: 1421305210, dlg start time: 0, DLG_lifetime: <null> I was wondering if any one could point out to me what I have set up wrong. Thanks in advance All the best. Will Ferrer Switchsoft

GeoIP Module and IPv6 seems not to match
by Jöran Vinzens 28 Jan '15

28 Jan '15

Hi All, i'm trying to get GEO IP Location for an IPv6 Setup. We downloaded the GeoLiteCityv6.dat from maxmind and referred to it in modparams of geoip. If i now place a call from an V6 User and do something like: if(geoip_match("$si", "src")) { xlog("L_NOTICE", "Call comes from IP '$si' ($gip(src=>cc)) CID=$ci F=$fU URI=$ru\n"); append_hf("X-GeoIP: $gip(src=>cc)\r\n"); } it will not match for any reason if i xlog the src IP it look like: "Src IP = 2A01:abc:321:123:0:0:0:2" so it should match to the GEO IP Database. In CSV version of geo IP database there is an entry for my IP Address. Since the Module is not that verbose, i cannot tell whether the entry exists or not. Just the result in my "if" is False. Has anybody experience with GEOIP and IPv6? thanks Best regards, Jöran

Rpc question
by Pars3c 27 Jan '15

27 Jan '15

Hi, I need to request to kamailio the list of all the active dialog (with some dialog variable). Now , i'm doing it with a program that call the proxy with the xmlrpc module. The problem is that when it arrive to 350-400 calls, the reply fail because it has no memory free. Now ,i have setted the pkg memory to 12MB but at peak it reply with error. Now i shoul increase it. Is there another method to optimize the request of these data, to avoid every time to increase the memory parameter? Thanks to all

Re: [SR-Users] Need help on WebRTC with Kamailio as proxy
by rahul.ultimate 27 Jan '15

Kamailio is just acting as a proxy and protocol modifier so to say. It is workin with rtpengine from sipwise to handle media as evident from he logs. This architectue uses a TURN server and the browser is chrome with latest updates. The only thing whih I haven't done is enable TLS in kamailio and create certs. (which I'm not completely sure how to do).. Also, does it necessitates to have Apache ruuning https on 443 ?
