missing BYE when 2 redundant kamailio servers share the same database
by Ding Ma 18 Mar '15

18 Mar '15

Hi, all I'm trying to set up 2 kamailio servers for active-active redundancy. The two kamailio severs share the the same database with db_mode=3, and no registration replication. Use pjsua2 as SIP client for testing. The test setup is as follows: kamailio server 1(k1): 10.0.1.30:5061 kamailio server 2(k2): 10.0.1.32:5061 sip client c1: sip:16317@10.0.1.30, client ip: 10.0.1.254 sip client c2: sip:72316@10.0.1.30, client ip: 10.0.1.254 c1 is registered with k1. c2 is registered with k2. When c1 calls c2, the call flow is as follows: INVITE: c1------>k1------>k2------>c2 200 OK: c1<------k1<------k2<------c2 So far, the INVITE works. c1 and c2 can establish a call. However, when c2 hangs up and sends BYE, the BYE is forwarded all the way to k1, and then k1 gives a 500 server error. The log on k1 seems to indicate k1 was attempting to create a TLS connection to itself instead of using the existing TLS connection to c1 to forward the BYE. BYE: c1 X k1<------k2<------c2 | |------->Connection refused/500 Here is the kamailio log on k1: Mar 16 10:34:21 kamailio.sip.com /usr/sbin/kamailio[13396]: ERROR: <core> [tcp_main.c:2740]: tcpconn_1st_send(): connect 10.0.1.30:55999 failed (RST) Connection refused Mar 16 10:34:21 kamailio.sip.com /usr/sbin/kamailio[13396]: ERROR: <core> [tcp_main.c:2750]: tcpconn_1st_send(): 10.0.1.30:55999: connect & send for 0x7fc96a68a1a0 failed: Connection refused (111) This is the routing logic for BYE in kamailio.cfg: if (loose_route()) { route(DLGURI); if (is_method("BYE")) { xlog("L_DBG", "=====BYE $ru from $fu $si:$sp to $du=====\n"); dlg_manage(); setflag(FLT_ACC); # do accounting ... setflag(FLT_ACCFAILED); # ... even if the transaction fails } else if ( is_method("ACK") ) { # ACK is forwarded statelessy route(NATMANAGE); } else if ( is_method("NOTIFY") ) { # Add Record-Route for in-dialog NOTIFY as per RFC 6665. record_route(); } route(RELAY); exit; } else {...... If I add location based routing for BYE from peer kamailio, then the BYE seems to be forwarded correctly: if (loose_route()) { route(DLGURI); if (is_method("BYE")) { xlog("L_DBG", "=====BYE $ru from $fu $si:$sp to $du=====\n"); dlg_manage(); setflag(FLT_ACC); # do accounting ... setflag(FLT_ACCFAILED); # ... even if the transaction fails # If BYE coming from Kamailio peer, route BYE by location $var(peerlist)=$sel(cfg_get.trusted.peers); $var(i) = 0; while($var(i)<$(var(peerlist){param.count})) { xlog("L_DBG", "=====$(var(peerlist){param.count})=====$(var(peerlist){param.valueat,$var(i)})=====\n"); if(src_ip==$(var(peerlist){param.valueat,$var(i)})) { lookup("location"); xlog("L_DBG", "=====BYE from $fu $si:$sp to $du=====\n"); break; } $var(i) = $var(i) + 1; } } else if ( is_method("ACK") ) { # ACK is forwarded statelessy route(NATMANAGE); } else if ( is_method("NOTIFY") ) { # Add Record-Route for in-dialog NOTIFY as per RFC 6665. record_route(); } route(RELAY); exit; } else {...... My first question is why k1 loose_route sends the BYE to itself instead of the client. Is this a bug? My next question is whether the above location routing for BYE from peer kamailio a good/safe approach. The SIP traces are enclosed. Thanks

Kamailio and Busy Lamp Fields (BLF)
by Daniel-Constantin Mierla 18 Mar '15

18 Mar '15

Hello, a bit of time ago I played with Kamailio and BLF, therefore I published kind of getting started configuration file for this feature. It is available at: - http://kb.asipto.com/kamailio:presence:k43-blf The plan was to add more to the tutorial, some guidelines for configuring the phones, but the time didn't allow it so far. Keep an eye on it for some new content. Contributions are also welcome, send them to me or take the content and publish it with new additions on another place. Hopefully is going to be useful for some people out there.

Redirect server for load balancing and HA
by Markus 18 Mar '15

18 Mar '15

Hi list, I'm new here, also to Kamailio. My goal is to achieve the "standard solution": Kamailio for load balancing and high availability of several Asterisk servers. For starters, I've set it up with Kamailio+dispatcher+permissions acting as a proxy and it was working fine, but I'd like to try to keep it much more simple. For these reasons: 1) I'd like to maintain different peer settings in Asterisk (DTMF, codecs). 2) I don't want/need a database for Kamailio. I think it is mandatory for permissions module + IP auth. So, let's do Asterisk the authentication, it's already there. 3) Accounting. I'm using a software where it's really useful for accounting purposes if every peer/user has its own entry in Asterisk's sip.conf / in realtime table. Long story short, my config now looks like this and it seems to be working fine for me: request_route { route(DISPATCHER); } route[DISPATCHER] { if ( method=="REGISTER") { ds_select_domain("1","4"); sl_send_reply("300","Redirect"); exit; } if ( method=="INVITE" ) { ds_select_domain("1","4"); sl_send_reply("300","Redirect"); exit; } if ( method=="SUBSCRIBE" ) { ds_select_domain("1","4"); sl_send_reply("300","Redirect"); exit; } } My questions: 1) There are other approaches to the DTMF+codecs issue. Like this thread from 2013: http://lists.kamailio.org/pipermail/sr-users/2013-January/076379.html - but I have dozens of changing PSTN peers, so authentication/accounting based on port would be cumbersome. Are there new/alternative ways? 2) I searched the archive and the Web but did not find many questions about a "I-don't-want-Kamailio-to-show-as-the-only-peer-to-Asterisk" solution. Therefore I'm wondering: Is everyone a) running such homogeneous setups that they can survive with the same codec + DTMF settings in Asterisk for all their peers + users? Or b) doing some rewriting magic within Kamailio to deal with it? Or c) I'm overlooking a simple solution. Which one is it? :) 3) And the biggest question: Everywhere I read basically "Redirect server for LB + HA is not recommended, better use proxy". Is this still true, and if so, what are the reasons? Because I should be worried that not all clients/gateways out there respect a SIP 300 Redirect? Other reasons? Thanks so much! :) Markus

msilo clarification
by mayamatakeshi 18 Mar '15

18 Mar '15

Hello, maybe this phrase in the msilo doc is misleading: *Every time when a user registers with Kamailio, the module is looking in database for offline messages intended for that user. All of them will be sent to contact address provided in REGISTER request.* http://kamailio.org/docs/modules/4.2.x/modules/msilo.html The above seems to imply that msilo would send the call directly to the contact address. But this doesn't seem to be the case based on what is mentioned in several threads in the mailing list and in what I saw in the msilo.c code. If so, is there a reason to be a such? Would it be a problem to allow msilo m_dump to get the values of contact, received and path and use them when calling t_request? Regards, Takeshi.

Dialogs not deleted on BYE
by Shane Harrison 18 Mar '15

18 Mar '15

Hi all, Have found a few threads on this before which have clarified my understanding a little but not yet presented me with a solution. I am using dialog_ng. dlg_manage() is deprecated and as per the documentation, I am simply setting a dialog flag early in the request_route. Kamctl dialog show does indeed show the dialogs are tracked, but they are not destroyed on the receipt of the BYE. Dialog ref count remains at 2 and in state=4 Log shows the following Mar 16 22:43:42 hh-rcs-sipproxy3 /usr/sbin/kamailio[15484]: DEBUG: tm [t_lookup.c:1373]: t_newtran(): DEBUG: t_newtran: msg id=16 , global msg id=15 , T on entrance=(nil) Mar 16 22:43:42 hh-rcs-sipproxy3 /usr/sbin/kamailio[15484]: DEBUG: tm [t_lookup.c:527]: t_lookup_request(): t_lookup_request: start searching: hash=5943, isACK=0 Mar 16 22:43:42 hh-rcs-sipproxy3 /usr/sbin/kamailio[15484]: DEBUG: tm [t_lookup.c:485]: matching_3261(): DEBUG: RFC3261 transaction matching failed Mar 16 22:43:42 hh-rcs-sipproxy3 /usr/sbin/kamailio[15484]: DEBUG: tm [t_lookup.c:709]: t_lookup_request(): DEBUG: t_lookup_request: no transaction found Mar 16 22:43:42 hh-rcs-sipproxy3 /usr/sbin/kamailio[15484]: DEBUG: tm [t_hooks.c:380]: run_reqin_callbacks_internal(): DBG: trans=0x7fc8d79af798, callback type 1, id 0 entered Mar 16 22:43:42 hh-rcs-sipproxy3 /usr/sbin/kamailio[15484]: DEBUG: dialog_ng [dlg_handlers.c:855]: dlg_new_dialog(): starting dlg_new_dialog and method is [BYE] Looks to me as if fails to find a dialog match and actually creates a new dialog..... Dialog_ng only has one matching mode - DID, others have been deprecated. I have captured the outgoing INVITE and there is no dialog_id parameter added to the record_route. Is that causing my matching problem?
