Load Balancing
by Tim King 29 Dec '10

29 Dec '10

I have read many examples and it seems I have found several pieces of how to do this but no real example of how to achieve this. I followed this setup guide: http://kb.asipto.com/freeswitch:kamailio-3.1.x-freeswitch-1.0.6d-sbc Performed this Kamailio install: http://www.kamailio.org/dokuwiki/doku.php/install:kamailio-3.1.x-from-git I have found the page for the dispatcher module here: http://kamailio.org/docs/modules/3.1.x/modules_k/dispatcher.html I also am curious if this dispatcher setup can be driven solely from the dispatcher mysql table or if the dispatcher.list file is required. Can someone point me towards the proper documentation that truly show how to configure these features. *SIP Routing Capabilities* - - NAT traversal support for SIP and RTP traffic - load balancing with many distribution algorithms and failover support - flexible least cost routing - routing failover - replication for High Availability (HA) * Load Based Load Balancing ** ------------------------- ** ** +----------+ ** | Kamailio | ** +----------+ ** | ** | +--------------+ ** |-------| FreeSWITCH 1 | [Calls 1,3,7] ** | +--------------+ ** | ** | +--------------+ ** |-------| FreeSWITCH 2 | [Calls 2,6] ** +--------------+ *

Kamailio 3.1.x and Asterisk 1.6.2 Realtime Integration using Asterisk Database
by Kurt Mullen 29 Dec '10

29 Dec '10

I am on my 20th (I'm not kidding) attempt to successfully complete this tutorial. I have installed on Ubuntu 10.10 x64 Server. I installed Kamailio & Asterisk on the same server as in the tutorial. I have two SIP clients registered, but they are not able to call each other. No one answered my last two posts, so I hope someone can help this time. Kurt Mullen

LCR and gateways resource.
by Ricardo Martinez 29 Dec '10

29 Dec '10

Hello. I’m looking for a way to mix the features of LCR and a counter to keep track of the used resource of a gateway. Let me explain. Let’s suppose that I’m using LCR module to route the calls to all my gateways, in particular I have the calls with prefix 55 routed to the group “55” which are 3 gateways : GW1, GW2 and GW3. Let’s suppose also that each gateway is connected to digital E1 with 30 channels. At certain time of the day one of the gateways is at full capacity using the 30 channels. This is what I wanted to do : can I have a variable with the maximum channels available for a certain gateway, and for each call going to that gateway a counter?. When the counter reach the maximum, can I remove the gateway from the LCR choosing algorithm until it has capacity again? Can I have some thoughts about this idea? Is there a way to achieve this ? Thanks in advance. Regards, Ricardo.-

Swap of From and To - kamailio 3.1.x problem?
by Jeremya 28 Dec '10

28 Dec '10

Hi I have a problem which pops up occasionally. My scenario is a kamailio 3.0.x server coupled with SEMS 1.2.1 Calls go to SEMS and occasionally it will issue a refer to the caller (an SPA962 linksys) The problem is that the refer seems to get screwed up somewhere and the referred call changes the From field to the To field - in this case 711. The problems start below at 15:58:21 after the refer I'd like to know if this is a problem with Kamailio or a problem with the phone. The call fails on the SEMS_SEND section when the From field is validated. I suspect the phone is the culprit, but external advice appreciated. I'm not quite sure what the s_xxx call id means? Here is the log Dec 24 15:58:20 mc0 /usr/local/sbin/kamailio[399]: WARNING: <script>: f43507d4-e02f109b(a)10.1.39.192 (New request) Method:<REFER> r-uri <sip:711@10.50.20.10:5070;LINEID=fac9f6b7cb08> To: sip:711@joondalup.fesa.sto From: sip:902@fesa.sto Dec 24 15:58:20 mc0 /usr/local/sbin/kamailio[399]: WARNING: <script>: f43507d4-e02f109b(a)10.1.39.192 ( reply etc ) Method:<REFER> r-uri <sip:711@10.50.20.10:5070;LINEID=fac9f6b7cb08> To: sip:711@joondalup.fesa.sto From: sip:902@fesa.sto Dec 24 15:58:20 mc0 /usr/local/sbin/kamailio[399]: WARNING: <script>: f43507d4-e02f109b(a)10.1.39.192 (Loose route) Method:<REFER> r-uri <sip:711@10.50.20.10:5070;LINEID=fac9f6b7cb08> To: sip:711@joondalup.fesa.sto From: sip:902@fesa.sto Dec 24 15:58:20 mc0 /usr/local/sbin/kamailio[399]: WARNING: <script>: f43507d4-e02f109b(a)10.1.39.192 (RELAY, start of processing) Method:<REFER> r-uri <sip:711@10.50.20.10:5070;LINEID=fac9f6b7cb08> To: sip:711@joondalup.fesa.sto From: sip:902@fesa.sto Dec 24 15:58:21 mc0 /usr/local/sbin/kamailio[399]: WARNING: <script>: s_275259592d_358d20ea49bf (New request) Method:<INVITE> r-uri <sip:7020@fesa.sto> To: sip:7020@fesa.sto From: sip:711@10.50.20.10:5070;LINEID=fac9f6b7cb08 Dec 24 15:58:21 mc0 /usr/local/sbin/kamailio[399]: WARNING: <script>: s_275259592d_358d20ea49bf (handle initial request) Method:<INVITE> r-uri <sip:7020@fesa.sto> To: sip:7020@fesa.sto From: sip:711@10.50.20.10:5070;LINEID=fac9f6b7cb08 Dec 24 15:58:21 mc0 /usr/local/sbin/kamailio[399]: WARNING: <script>: s_275259592d_358d20ea49bf (t_check_trans) Method:<INVITE> r-uri <sip:7020@fesa.sto> To: sip:7020@fesa.sto From: sip:711@10.50.20.10:5070;LINEID=fac9f6b7cb08 Dec 24 15:58:21 mc0 /usr/local/sbin/kamailio[399]: WARNING: <script>: s_275259592d_358d20ea49bf (Request For Me) Method:<INVITE> r-uri <sip:7020@fesa.sto> To: sip:7020@fesa.sto From: sip:711@10.50.20.10:5070;LINEID=fac9f6b7cb08 Dec 24 15:58:21 mc0 /usr/local/sbin/kamailio[399]: WARNING: <script>: s_275259592d_358d20ea49bf (SEMS, rewrites) Method:<INVITE> r-uri <sip:020@fesa.sto> To: sip:7020@fesa.sto From: sip:711@10.50.20.10:5070;LINEID=fac9f6b7cb08 Dec 24 15:58:21 mc0 /usr/local/sbin/kamailio[399]: WARNING: <script>: s_275259592d_358d20ea49bf (SEMS_SEND) Method:<INVITE> r-uri <sip:020@fesa.sto> To: sip:7020@fesa.sto From: sip:711@10.50.20.10:5070;LINEID=fac9f6b7cb08 Dec 24 15:58:21 mc0 /usr/local/sbin/kamailio[398]: WARNING: <script>: s_275259592d_358d20ea49bf (SEMS_SEND_REPLY) Method:<INVITE> Status:<603> Dec 24 15:58:21 mc0 /usr/local/sbin/kamailio[398]: CRITICAL: <script>: s_275259592d_358d20ea49bf (SEMS_SEND_FAIL) Method:<INVITE> Status:<<null>> Dec 24 15:58:21 mc0 /usr/local/sbin/kamailio[404]: WARNING: <script>: s_275259592d_358d20ea49bf (New request) Method:<ACK> r-uri <sip:7020@fesa.sto> To: sip:7020@fesa.sto From: sip:711@10.50.20.10:5070;LINEID=fac9f6b7cb08 Dec 24 15:58:21 mc0 /usr/local/sbin/kamailio[404]: WARNING: <script>: s_275259592d_358d20ea49bf ( reply etc ) Method:<ACK> r-uri <sip:7020@fesa.sto> To: sip:7020@fesa.sto From: sip:711@10.50.20.10:5070;LINEID=fac9f6b7cb08 Dec 24 15:58:21 mc0 /usr/local/sbin/kamailio[404]: WARNING: <script>: s_275259592d_358d20ea49bf (Not a loose route) Method:<ACK> r-uri <sip:7020@fesa.sto> To: sip:7020@fesa.sto From: sip:711@10.50.20.10:5070;LINEID=fac9f6b7cb08 Dec 24 15:58:21 mc0 /usr/local/sbin/kamailio[404]: WARNING: <script>: s_275259592d_358d20ea49bf (ACK in lr) Method:<ACK> r-uri <sip:7020@fesa.sto> To: sip:7020@fesa.sto From: sip:711@10.50.20.10:5070;LINEID=fac9f6b7cb08

Source IP address in Failure_route
by Ricardo Martinez 24 Dec '10

24 Dec '10

Hello. I’m trying to obtain the source IP address from a reply message. This is part of the configuration file : failure_route[1] { if (t_was_cancelled()) { xlog("L_INFO", "[$ci] $rm:$ru t_was_cancelled in failure_route\n"); exit; } if ( ($T_rpl($si) != "10.0.0.4") || ($T_rpl($si) != "10.0.0.3") ) { if ( t_check_status("48[0-9]") ) { xlog("L_INFO","[$ci] 48X Received\n"); exit; } } … But it seems not to be working. Is there a way to do what I want? Thanks in advance, Regards, Ricardo.- * *

[dialog] No dialog stored if Via has no branch
by Iñaki Baz Castillo 23 Dec '10

23 Dec '10

Hi, using Kamailio 1.5.4. I receive llamadas from a Cisco pre-RFC 3261 (non symmetric SIP and no ;branch parameter). It seems that dialog module cannot account such calls. Maybe branch parameter is required? -- Iñaki Baz Castillo <ibc(a)aliax.net>
