I'm using allow_address function of the permissions module and I'm seeing strange behavior with network masks not divisible by 8. I have 172.16.0.0/12 in my address table and Kamailio is marking packets from 172.56.16.232 as being part of that local subnet. If I change the subnet to 172.16.0.0/16, I no longer have an issue. I know there was a bug several years ago related to this ( http://git.kamailio.org/gitlist/index.php/sip-router/commit/0ead7ab31bf0df6…), but that code is very different, so I'm wondering if a regression has crept in? I'm using Kam 4.1.6.

dmq_replicate deserializing?

by Asgaroth

Hi All, I am playing with the new dmq_replicate module and am banging my head against an issue I have come accross. I can see the kamailio registrars sending the replication messages to the other node(s) in the dmq bus, and the payload looks to be of type json. However, on the recieving nodes, when I try to issue a kamctl ul show --brief, the output of the AOR's are garbled. I had a look at the dmq/dmq_ursloc moduled, and the dmq module docs mention that we may need to load our own deserializers, is this the case when using the dmq_usrloc module as well? I am only using dmq to replicate registration messages. Here is a sample of the dmq workers on a recieving node applying the update, and you can see that it thinks the contact to add is 'p÷#031#002', is was expecting the actual AOR of the subriber to show up here. Am I missing something simple here or is there something more sinister at play. Any pointers would be greatly appreciated.

IMS server with a core network

by test testt

hello, I posted a message in the kamailio forum but it wasn't in the good place, so I rebroadcast at this e-mail as it was say. Hello, I have installed Kamailio 4.2 and I would like to use it as IMS server but I don't have any ideas how to do this. I have a LTE core network which includes HSS ans PCRF. I saw on this page ( http://www.kamailio.org/w/2013/05/ims-kamailio/ ) that is apparently easy, just need to take the P-CSCF, S-CSCF and I-CSCF Kamailio and Diameter config files in the examples folder and run kamailio but I don't know how to use them and I didn't find any tutorials about it. Could you help me please ? Marc link: https://github.com/kamailio/kamailio/issues/227#issuecomment-118073500 I tried the 2 tutorials that it has given but it's not really working I am using ubuntu 15.04 Thanks Marc

Dispatcher, Failure Route and fr_timeout

by Asgaroth

Hi All, I would like to reduce the time it takes for kamailio to timeout an initial message to a dispatcher destination so that it will select the next destination in the set, before, hopefully, a restransmission. In this case I am testing registration messages. I came accross the t_set_fr() function in the TM module documentation today and have been experimenting with it for some hours. I have an issue where a 408 timout is sent back to the UAC before the last destination in the dispatcher set is selected, I suspect I am hitting the timeout somewhere, but I cannot see where, I presume the fr_timeout is set every time I issue the t_set_fr() call and the associated t_relay. I'm just wondering if I am doing this correctly, if one of the guru's out there wouldnt mind casting an eyeball over this config and let me know if I am on the right track, or if I am going about this in the wrong way. Any suggestions are most welcome. What appears to be happening is, I have 3 destinations in the dispatcher set, it looks like the 1st 2 are tried, which correctly timeout and are set inactive-probing, but on the last destination, which is working, I appear to be getting a 408 timeout being sent back from kamailio. Here is a snip of my configuration: #!define NO_RESPONSE_TIMER 250 request_route { t_on_failure("DISPATCHER_FAILURE"); t_set_fr(0, NO_RESPONSE_TIMER); if(!ds_select_dst("1", "0")) { xlog("L_ERR", "No dispatcher destinations available for $ru\n"); sl_send_reply("500", "No destination available"); exit; } route("RELAY") } route[RELAY] { if (!t_relay()) { sl_reply_error(); } exit; } failure_route[DISPATCHER_FAILURE] { if (t_is_canceled()) { exit; } # select next destination only for local timeout if (t_branch_timeout() && !t_branch_replied()) { xlog("L_INFO", "route[DISPATCHER_FAILURE] : $rm : timeout and no reply ($si:$sp->$Ri:$Rp->$du)\n"); xlog("L_INFO", "route[DISPATCHER_FAILURE] : $rm : setting $du to probing state"); ds_mark_dst("ip"); if(ds_next_dst()) { xlog("L_INFO", "route[DISPATCHER_FAILURE] : $rm : next destination selected ($du)\n"); t_set_fr(0, NO_RESPONSE_TIMER); t_relay(); exit; } else { xlog("L_INFO", "route[DISPATCHER_FAILURE] : $rm : No destinations available for $rd"); send_reply("500", "No destination available"); exit; } } }

clarification on tcp keepalive

by Kelvin Chua

using kamailio 4.3 on ubuntu server 14.04 i noticed tcp socket will be killed by kamailio after around 11 minutes with or without tcp_keepalive=no. tcpdump shows that by default (tcp_keepalive=yes) there is indeed keepalive packets going back and forth. if set to no, there would be nothing in between. if i have clients who have registration timeout of 1700, they would send re-registration around half of that, or around 14 minutes after registration. then the socket would be long dead and they would be unreachable for 3 minutes. based on procfs, ubuntu have settings for 9 probes with 75 seconds interval so that means around 11 minutes of sending keepalives. so i tried changing these values, on procfs. and tried playing around with these kamailio cfg settings as well: tcp_keepcnt tcp_keepidle tcp_keepintvl whatever i do, the interval between keepalives are always 2 minutes and after 4-5 probes, kamailio will send a FIN to the client. i checked the source code tcp_main.c and it looks alright. could this be an ubuntu issue? anybody seen this before? I created a workaround by setting expire 900 for all registrations but this is not ideal. Kelvin Chua

DIAMETER based on TCP requires a FIXED I/S-CSCFSOURCE PORT in order to make Cx work towards a External HSS

by Jan Devai

Hi experts, from the current trace we can see that the I/S-CSCF always changes SOURCE port when contacting our eternal HSS. In order to make the Cx work HSS expects the Source port to be fixed on the TCP layer and in our I/S-CSCF configuration we did not find any setting for SOURCE Port. Can somebody help us please ;-) ? We appreciate your support, Br, Jan
