How to get call on an extension, which is registered when a call towards it reach kamailio. How to modify pending session parameters in kamailio?

by Arun NV

Hi, I am using *Kamailio 4.4* as the proxy with my *Asteri**sk *server. I am trying to develop a scenario where an extension gets registered on asterisk via *Kamailio *when it receives a push notification. This push notification is sent to the sip extension when a call towards this extension reaches to the *Kamailio*. For example, suppose there is two SIP extension(* extension 1 and extension 2*) registered on *Asterisk *via Kamailio. When a call from *extension 1* reaches the asterisk, it forwards the *INVITE *request towards *extension 2* via Kamailio.Kamailio will try to forward it to extension 2. suppose the *extension 2* is not able to receive the *INVITE *request from *Kamailio*. When extension two receive a push notification, it will register on asterisk. So I need to get the call on *extension 2 *through the new registration. We are trying to simulate registration of extension to the asterisk when receiving the push notification. First, we registered *extension 2 *and disconnected the network. Then we tried to register the same extension when a call from *extension 1 *reaches to Kamailio. This is a simulation of push-based registration since an extension that receives the push will attempt to register when an incoming call is received. When asterisk sends *INVITE *request to Kamailio, it immediately responded with *100 trying* provisional response. This *100* response by Kamailio towards asterisk prevents asterisk from re-transmitting the INVITE. Then Kamailio tried to send and retransmit the packet to *extension 2*, which does not have network access. This* extension 2 *was on port number *24071*. Even after successful registration(in port *59995*) of the *extension 2*, Kamailio continued to transmit the packets to the old port. After that, we have configured Kamailio in a way that it won't send an immeadeate provisional reply(*100 trying* ) for *INVITE *request. Here Kamailio is not immediately sending *100 trying* message to *Asterisk*. This forces Asterisk to re-transmit. Asterisk was found to retransmit the same packets. However, even after the successful registration of* extension 2*, asterisk continued to send the old invite to Kamailio not the new one to the latest port. This is the problem for me since push relies on the *INVITE *reaching the phone at the correct port number. So, is there other good approaches to solve this issue? One thing I would like to try is modifying the pending *INVITE *request towards old registered port with the new port details when new registration reaches to Kamailio. Can I get the ongoing requests from Kamailio? Please suggest a viable solution. Thank you, Arunbalan

In need of a simple, stateless 302 redirect for INVITE

by Robert

Hello again, I am not a SIP expert, and I’m new to Kamailio, really enjoying learning it, but I’ve hit a blocker and I’m pretty sure I’ve missed something really simple. I’m looking to implement the Redirect Server from here: https://tools.ietf.org/html/rfc3665#section-3.6 <https://tools.ietf.org/html/rfc3665#section-3.6> (the Avaya Session Manager being Alice), Kamailio as the Redirect Server. My configuration is working fine, and I can see the 302 going back (to Avaya SM), I then get the ACK I’m expecting. The incoming SIP request contains a number of fields, including a Contact header, which I’m told SM needs on the return. But the send_reply() or sl_send_reply() doesn’t return the Contact header, and I am unable to manually set it, or any other header, using any of the append_hf(), append_to_reply() etc. mechanisms. I’m executing a msg_apply_changes() which succeeds, but no Contact header is returned. I’ve tried an sl_send_reply(“100”, “Trying”) before any other processing, and Wireshark confirms that the SIP response is basically identical to the 302 response sent after processing… The goal is to run this stateless, I’m assuming this is possible - it certainly feels like it should be. I’ve re-read the intros & tutorials, and other reading material such as this http://kamailio.org/docs/ser-getting-started/SER-GettingStarted.pdf <http://kamailio.org/docs/ser-getting-started/SER-GettingStarted.pdf> but, this, even my best Google-fu has left me utterly stumped… The sl_send_reply documentation https://kamailio.org/docs/modules/5.2.x/modules/sl.html#sl_send_reply <https://kamailio.org/docs/modules/5.2.x/modules/sl.html#sl_send_reply> states “If the code is in the range 300-399 (redirect reply), the current destination set is appended to the reply as Contact headers” but the Contact header is definitely not being set when I use this. Apologies in advance if eyes are rolling and this is really obvious, or (and?) that my lack of SIP knowledge is shining through - any tips or guidance would be appreciated. I certainly feel overwhelmed by the number of modules and the interplay between them. If the answers to this, and other things along these lines are contained in the admin book, that’s fab, I’ve just filled the form out :) Cheers - Robert...

DBURL password in clear

by Robert

Hello, I’m working for a UK high street bank and our Kamailio implementation has been challenged because we’ve got database passwords held in clear in the configuration file. I am unable to find any examples of where this has been worked around, there doesn’t seem to be any module or configuration means of supplying a variable in the modparam() entry that is expanded a startup. The security tutorials only seem to relate to the SIP level of security, not Kamailio as a platform. My requirement is simple, I need to be able to supply a password via means such as loading a variable from a run-once script at start up, or a module. The ideal would be to be able to read in a Docker secret :) I am by no means a Kamailio expert, so apologies in advance if this is a mindblowingly basic thing to achieve, but I do feel I’ve exhausted the Kamailio documentation, wiki etc. and all the goodness Google usually has to offer and drawn a blank. Sincere thanks in advance for any assistance. Cheers - Robert...

parse_from_header(): bad From header

by Donat Zenichev

Hi community. We experience the problem with malformed messages. First of all, I want to say, that most of time kamailio works well and nothing happens that can drop sessions. But from time-to-time something changes (may be in the network) and kamailio receives requests with malformed headers (To or From hfs). The schema: uplinks -> kamailio <-> routing server (asterisk) Malformed messages were received only from asterisk server. Sip debug on asterisk showed that messages were transmitted correctly and headers were nice. But kamailio obtains changed (broken) packets or perhaps can't read them properly. How does it look like: Nov 10 12:37:06 kamailio-name kamailio[965]: INFO: <script>: Going to NATMANAGE for BYE from sip:useragent7122@kamailio_address:5068 (IP=wss:client_address:62881) - R=sip:dialed_did_service@asterisk_address:50600 ID=1b0044070de406153bf0e4b84d6bb793@asterisk_address:50600 Nov 10 12:37:06 kamailio-name kamailio[965]: NOTICE: <script>: Relaying request to <null> - R=sip:dialed_did_service@asterisk_address:50600 ID=1b0044070de406153bf0e4b84d6bb793@asterisk_address:50600 Nov 10 12:37:06 kamailio-name kamailio[965]: ERROR: <core> [parser/parse_addr_spec.c:719]: parse_addr_spec(): unexpected char [<] in status 6: [<sip:useragent6] .

Source socket/port for in-dialog requests

by Donat Zenichev

Hi community. My apologies for so frequent appealing to you. I'm trying to solve problem with ending of sessions. The problem consists of no 200 OK coming from uplink on our BYE requests. Topology. First leg: Webrtc client <-wss-> kamailio <-sip tcp-> asterisk routing server Second leg: Uplink <-sip tcp-> kamailio <-sip tcp-> asterisk routing server The problem appears only in case when dialog was ended by webrtc client. The first leg (dialog) of the call ends nice, without any hints on problem. But the second leg (with uplink) has problem with no 200 OK (coming from uplink) on BYE request coming from asterisk. Handshake between asterisk server and uplink establishes properly. It looks like: uplink.domain.com:5060 -> INVITE tcp -> our.kamailio.server:5060 -> INVITE tcp -> our.asterisk.server:5060 . uplink.domain.com:5060 <- 100 trying tcp <- our.kamailio.server:5060 . uplink.domain.com:5060 <- 180 ringing tcp <- our.kamailio.server:5060 <- 180 ringing tcp <- our.asterisk.server:5060 . uplink.domain.com:5060 <- 200 OK tcp <- our.kamailio.server:5060 <- 200 OK tcp <- our.asterisk.server:5060 . uplink.domain.com:5060 -> ACK tcp -> our.kamailio.server:5060 -> ACK tcp -> our.asterisk.server:5060 . uplink.domain.com <-media stream-> rtpengine <-media stream-> our.asterisk.server . Here kamailio starts to use random source port for relaying in-dialog BYE uplink.domain.com:5060 <- BYE tcp <- our.kamailio.server:45355 <- BYE tcp <- our.asterisk.server:5060 . And here the leg with uplink is expected to end with 200 OK (coming from uplink proxy). But uplink doesn't answer at all. We requested a tcpdump from uplink to see how packets are forwared from their side. And I saw that that 200 OK tries to be sent within first tcp session - to 5060 port of kamailio server. But sngrep on our side shows nothing, nothing appears in kamailio log, so 200 OK can't reach the 5060 socket because of some transport problem I think. Top via hf of our BYE request, contains kamailio record = uplink.domain.com:5060 My main thought on this count is to suppress using of random source ports for in-dialog requests, this behaviour looks irrelevant. We have turned on mhomed parameter (mhomed=1). And cookbook says: "Set the server to try to locate outbound interface on multihomed host. This parameter affects the selection of the outgoing socket for forwarding requests." But, there is a big but - we can not turn of this parameter for this moment, because routing script made with using of this one. Kamilio works on AWS EC2 platform. It has following IP address schema: private address atouched to container -> public address assinged to this private address (so this is standard ip address schema for AWS containers). For this example private address will be: 10.0.0.1 and public address will be: 100.0.0.1 Configuration - main parameters (all values are changed for an example): advertised_address=our.kamailio.server advertised_port=5060 alias=our.kamailio.server alias=our.kamailio.server:5060 alias=100.0.0.1 alias=100.0.0.1:5060 alias=10.0.0.1 alias=10.0.0.1:5060 auto_aliases=no port=5060 listen=100.0.0.1 listen=10.0.0.1 listen=tcp:100.0.0.1:5060 listen=tcp:10.0.0.1:5060 mhomed=1 fork=yes fork_delay=5000 children=6 tcp_connection_lifetime=3604 tcp_accept_no_cl=yes tcp_connect_timeout=5 tcp_send_timeout=5 tcp_rd_buf_size=16384 tcp_keepalive=yes tcp_crlf_ping=yes tcp_keepcnt=3 tcp_keepidle=30 tcp_keepintvl=15 tcp_max_connections=4096 One of the solutions to this problem was to add following inside the relaying route block: $fs = "tcp:" + "10.0.0.1" + ":5060"; if (!t_relay()) { sl_reply_error(); } But it seems to me it's not a smart solution. -- -- BR, Donat Zenichev Wnet VoIP team Tel Ukraine: +380(44) 5-900-800 Tel USA: +164(67) 8-174-17 https://w-net.us/ <http://wnet.ua> <http://www.avg.com/email-signature?utm_medium=email&utm_source=link&utm_cam…> Virus-free. www.avg.com <http://www.avg.com/email-signature?utm_medium=email&utm_source=link&utm_cam…> <#DAB4FAD8-2DD7-40BB-A1B8-4E2AA1F9FDF2>
