Addressing a distinct PSI result is: 555 AS Contacting Failed - iFC terminated dialog
by Valentin Christoph 05 Oct '16

05 Oct '16

Hi all, I'm trying to send a call to an AS via a kamailio S-CSCF (release 4.4.3). I'm addressing the AS by a distinct PSI: sip:04325432101@domain.net;user=gsmr. At the first try the S-CSCF sends a SAR to HSS and receives a successful SAA (tshark traces attached), but the S-CSCF rejects the call with 555 AS Contacting Failed - iFC terminated dialog. At the second try (a few seconds later), the S-CSCF doesn't exchange SAR/SAA with the HSS, and now the call is successfully forwarded to the AS. This problem is permanent, it is not the result of a temporary loss of connectivity between S-CSCF and AS. I checked the iFCs that I had configured at the HSS and I think, they are OK. I attached - tshark traces from the node, where the S-CSCF resides: 2016_09_19_error_555_17_scscf_filtered.pcap - WITH_DEBUG logs from kamailio: 2016_09_19_error_555_17_kamailio_1st_try.log - A tarball of /usr/local/etc/kamailio: 2016_09_19_error_555_17_kamailio.tar.gz Can anybody help? Is it a bug in kamailio or is the problem on my side? Thanks, Christoph The information contained in this e-mail message is privileged and confidential and is for the exclusive use of the addressee.

by Surender Singh 03 Oct '16

03 Oct '16

Hello, Thanks to all to develop the such type Sip Proxy server. Please suggest whether SIP proxy server is open source ,If yes than it can fulfil the my below requirement . 1) I having some sip clients which are registered on IMS .Can I use the kamailio Sip proxy sever between sip client and IMS. Sip client ------------------Kamailio Sip Proxy ---------------IMS 2) Second things, can I use Kamailio Sip Proxy to interconnect two IMS nodes . Can I create the SIP trunk without registration mode (username and password) between IMS nodes using Kamailio. Because the my IMS node doesn't support sip trunk in registration mode. Its support one normal trunk (SIP-T) My current IMS set up like below. IMS-1 (IBCF)---------------IMS2(IBCF).

Call forking priority
by Igor Potjevlesch 30 Sep '16

30 Sep '16

Hello list, I have a proxy that manage fix calls and a proxy that manage mobile calls. I want to implement call forking so when I call to a fix phone the call goes to the fix proxy and it forks to the mobile proxy who manage the call and viceversa. I want the fix to ring 2 or 3 times before the mobile. In order to do so I relay first to the fixed proxy, which will bounce back to mobile proxy the branch for mobile device. But now if I want to be able to choose which phone (mobile or fixe) rings before I have tried by doing the "async_route("RELAY", "7");" in the fixe proxy like in the mobile proxy but it doesn't work. My code is: Fix proxy: if($rU==123456789){ add_diversion("forking"); $var(priority)=1; append_branch("sip:987654321@proxy_mobile"); } route[INVITE]{ if($var(priority) == "1"){ async_route("RELAY", "7"); }else{ route(RELAY); exit; } Mobile proxy: if($tU==987654321){ $rU=123456789; } route[INVITE]{ if($dir == "forking"){ async_route("RELAY", "7"); }else{ route(RELAY); exit; } } Thanks.

ims_charging state machine issue

30 Sep '16

Wanted to ask about changing rates while a call is not yet connected. I did this, $var(cc_ret1) = Ro_CCR_Stop("term", "487", "Request Terminated"); $var(cc_ret2) = Ro_CCR("RO_REPLY", "term", 30, "1", "1"); however, upon sending the new CCR, i get this ERROR: cdp [acctstatemachine.c:185]: cc_acc_client_stateful_sm_process(): Received unknown event [1] in state [1] and CRITICAL: ims_charging [ro_timer.c:122]: insert_ro_timer(): Trying to insert a bogus ro tl=0x7f484ab48728 tl->next=0x7f484ab42858 tl->prev=0x7f484aaa1090 looks like there is some statemachine issue. question is, how do we change rate? ---- Sent using GuerrillaMail.com Block or report abuse: https://www.guerrillamail.com/abuse/?a=UlM5EB4FUac1hAen5G1RYR3XANifx8NV1epN…

Identical Kamailio setup on 2 hosts
by Infinicalls Infinicalls 30 Sep '16

30 Sep '16

Hi, I have two identical hosts running Kamailio with the same set of users. They are located in different locations. Both are running behind NAT and I've enabled rtpproxy for that and also advertised the public IP. Both the MySQL DBs are similar and have the same data. Both the hosts have different sub-domains in alias and I have set auto_alias=no Now, the problem is my users are not able to communicate from one server to another. user1(a)mydomain.com from host1 is not able to communicate to user1(a)mydomain.com at host2, though inter-server communication is happening nicely. Any idea how to solve this? Thanks. regards Ganesh Kumar -- --- http://www.infinicalls.com

Load balancing traffic with Kamailio
by Nitesh Bansal 29 Sep '16

29 Sep '16

Hello, I'm planning on doing some smart load balancing with Kamailio. We have a distributed network, with multiple Kamailio boxes in different locations serving as Ingress SBC, these Kamailio boxes are the entry point for a SIP call and then they route the call to a pre-configured Asterisk boxes. I want to move away from this, I would like these Kamailios to be able to distribute the traffic to Asterisk boxes based on the performance of the Asterisk ,it would be great if we could take a look at SIP response time from Asterisk and use that as metric for load balancing the traffic) Is there any Kamailio module which could do that? Do I need to integrate some other tool with Kamailio to achieve this? Any suggestions are welcome. -- *Nitesh Bansal* Business Development Engineer http://www.voxbone.com/

Re: [SR-Users] Distributed Message Queue Module
by Charles Chance 29 Sep '16

Hello, That depends entirely on what you need to replicate between servers. DMQ is just a communication channel. How you use it is up to you. For example, if you enable dmq_usrloc, there's no need to share a location database. Htable has an option for replicating over dmq too. The number of direct module integrations like dmq_usrloc/htable is fairly limited, but you can also share arbitrary data between nodes yourself from within your config. I think you'll need to provide a little more information about what you're trying to achieve, however, in order for us to offer any further advice.

Hello, i'm trying to list the dialog (dlg_profile list) in the proxy using an RPC call to jsonrpc-s (dlg_profile list). But when there are many calls , kamailio send an error because the tcp buffer is not big enough. The only solution is to increase the parameter tcp_conn_wq_max every time i've an error ? Thanks
