[Kamailio-Users] Problem starting Kamailio
by Sara EL KABIRI 09 Mar '09

09 Mar '09

Hello, I've installed kamailio 1.4.3 (without tls) on ubuntu by following the provided INSTALL guide. I want to use it as a presence server but i've got some problems creating the MySQL database: I got this error : *ERROR* *1105* (HY000): *MyISAM* *table* ‘version′ *is* *in* *use* (*most* * likely* *by* *a* *MERGE* *table*). *Try* *FLUSH* *TABLES*… Could anyone help please? -- Sara

[Kamailio-Users] lcr-module, ping and load_gws_from_grp (kamailio 1.5)
by Stefan Prelle 09 Mar '09

09 Mar '09

Hi, I just noticed something weird when working with the lcr module. My setup has 5 gateways - 4 in group 1, one in group 2. The lcr-table has an entry for each group, both reacting on the same prefix. I am using load_gws_from_grp("1") to get a gateway for a target. This usually works fine. If now all 4 gateways in group 1 ar disabled because the alive check failed, load_gws_from_grp("1") returns the gateway from group 2 (or other groups where the prefix from the lcr-table matches. I would consider this a bug, since I explicitly requested gateways from a specific group. Regards, Stefan

[Kamailio-Users] Send a status from reply route
by Kévin L'heveder 09 Mar '09

09 Mar '09

Hi, I work with Kamailio as Proxy and a call manager. From a MI_datagram script I manage kamailio. My script check the current data rate on different links. So if the max data rate is reached my script must cancel the call. That works good because I can use t_reply or sl_send_reply from request route and send cancel or status error. But in one case I need to cancel the call after receiving the trying (after INIVTE) from the call manager (because the call manager could preempt a call to free some space one the link) My trouble is that i can't use t_reply or sl_send _reply from REPLY_ROUTE and to cancel the call properly i need to send a status error, so i can't use t_uac_dlg from my management interface (because this function sends request only). I didn't find out a solution to do this, so is someone have one ...?

[Kamailio-Users] reseting of t_on_branch, t_on_reply and t_on_failure
by jh＠tutpro.com 09 Mar '09

09 Mar '09

i have noticed that i need to call again t_on_branch, t_on_reply and t_on_failure in failure route before calling again t_relay, i.e., successful call of t_relay resets these settings and they need to be re-armed. how about if t_relay fails and transaction is not created? are the t_on_X calls still in effect or do they need to be re-armed again? i haven't found in tm/README any discussion about when the t_on_X calls get reset. -- juha

[Kamailio-Users] SIP Re-Routing using Private Header
by Geoffrey Mina 08 Mar '09

08 Mar '09

Hello, I have a problem which I am not sure the best way to solve with Kamailio. I have many asterisk servers which use Kamailio as their outbound gateway to route calls to the PSTN. This works great, I use the LCR engine to control routing. What I want to do is have the ability to dial a random SIP URI from my asterisk servers, but route the call through my Kamailio server for accounting and security purposes. My asterisk servers are not allowed SIP messaging from anything other than my Kamailio gateway. What I am considering doing is something like this: Since asterisk is fairly limited in your ability to route calls, I need to do a little magic to make the call route through a proxy. Maybe I'm wrong, but I haven't yet been able to figure it out. My theory is that I will add a special header at the asterisk level and send the invite to Kamailio. [test] exten => 1,1,SipAddHeader("P-Forward-URI: bob(a)somedomain.com") exten => 1,n,Dial(SIP/forward@kamailio,30) [From Asterisk To Kamailio] INVITE sip:forward@10.1.1.1 SIP/2.0 Via: SIP/2.0/UDP pc33.atlanta.com;branch=z9hG4bK776asdhds Max-Forwards: 70 To: <sip:forward@10.1.1.1> From: "" <sip:5555551212@pc33.atlanta.com>;tag=1928301774 Call-ID: a84b4c76e66710(a)pc33.atlanta.com CSeq: 314159 INVITE Contact: <sip:5555551212@pc33.atlanta.com> Content-Type: application/sdp Content-Length: 142 P-Forward-URL: bob(a)somedomain.com if(is_present_hf("P-Forward-URL")){ //what do i do here to rewrite the To and INVITE parts before doing record_route() and t_relay() } Maybe I'm totally off track here, but this is all I have come up with so far! Perhaps there is a mechanism in SIP which already allows me to do this, and I don't know about it... I don't know what I don't know :) Thanks, Geoff

[Kamailio-Users] Need help terminating inbound and outbound calls from PSTN!!!!
by carl Lougher 07 Mar '09

07 Mar '09

Hi, I finally managed to get outbound calls working to the PSTN but am struggling with the inbound ones. Current setup: Kamailio 1.5 Sip trunk to Trixbox using username and password stored in Kamailio db PSTN - Gateway only using ip address and no auth. Questions: 1. Am i using the correct method for terminating outbound calls from the Trunk? Currently using rewritehostport off invite. 2. I've tried using allow trusted for the inbound calls from the PSTN GW but they do not connect to the sip trunk. Although i do see the call coming in using ngrep. 3. How do i pass multiple inbound calls to the trunk when it only has one number associated to it in the db? 4. Is there a better method for terminating calls in and out from asterisk/trixbox on sip trunks? cfg file: Last login: Sat Mar 7 14:25:33 2009 from 121-73-118-198.cable.telstraclear.net [root@zedd ~]# cat /usr/local/etc/kamailio/kam kamailio.cfg kamailio.cfg.working kamailio.cfg.working2 kamctlrc [root@zedd ~]# cat /usr/local/etc/kamailio/kamailio.cfg # # $Id: kamailio.cfg 5652 2009-03-02 11:13:38Z henningw $ # # Kamailio (OpenSER) SIP Server - basic configuration script # - web: http://www.kamailio.org # - svn: http://openser.svn.sourceforge.net/viewvc/openser/ # # Direct your questions about this file to: <users(a)lists.kamailio.org> # # Refer to the Core CookBook at http://www.kamailio.org/dokuwiki/doku.php # for an explanation of possible statements, functions and parameters. # # There are comments showing how to enable different features in th econfig # file.

[Kamailio-Users] LCR Documentation
by Geoffrey Mina 07 Mar '09

07 Mar '09

Hello, I am currently deploying the LCR module. I have some questions about fields and what they do... I searched the docs, but couldn't find anything. Can someone please fill in the blanks? [LCR Gateways] Gateway Name: description of the gateway Group ID: Numeric identifier used to link LCR Rules IP Address: The IP of the SIP gateway Hostname: The hostname of the SIP gateway (not required if IP provided?) Port: The port the SIP gateway listens on URI Scheme: (well documented) NULL = sip, 1 = sip and 2 = sips Transport: (well documented) NULL = none, 1 = udp, 2 = tcp, 3 = tls, and 4 = sctp Strip: ? Tag: ? Weight: ? Ping: ? Flags: ? [LCR Rules] Prefix: The matching prefix. In the US most would do this by area code, so I would assume I would put something like 1678 or 1770 to route Atlanta calls. Would putting a NULL or Empty String force a default route for everything? >From URI: If I don't care about the from URI can I leave this NULL or BLANK? Group ID: The numeric identifier matching to LCR Gateways Priority: I am assuming if there are 2 records which match the prefix and from URI the high priority will be chosen first? Also, say for example, one of my gateway providers has a primary and a secondary gateway. If the primary is down I need to route calls to the secondary. How would this fit into an LCR scheme? Would I need duplicate routes for the secondary with a lower priority? Thanks, Geoff p.s. for anyone holding out, I just installed Siremis today and it rocks! I am really quite pleased with the solution.
