Hello there, I have NDB_MONGODB loaded in kamailio with following configurations: *loadmodule "ndb_mongodb"* *modparam("ndb_mongodb", "server",

rtpengine_offer() with ICE not updating o= and m= IP addresses
by David Dean 22 Apr '19

22 Apr '19

I'm using the following rtpengine_offer() to force the use of ICE relay and also replace o= and m= rtpengine_offer("replace-origin replace-session-connection ICE=force-relay RTP"); The SDP is being updated to include an ICE relay candidate, but the IP addresses in the o= and m= lines are not changing to the servers IP address (X.X.X.X). I also tried using the media-address parameter but that didn't change the behaviour. When I use rtpengine_answer() then it's not providing an ICE candidate nor changing o= or m=, which I imagine is expected. What am I missing?

Config to control TCP connection reuse
by R, Rajkumar (Raj) 22 Apr '19

22 Apr '19

Hi, In my setup(kamailio in stateless mode to a backend server), for any number of client registrations kamailio (in stateless mode) is reusing the TCP connection. Let's say if I register 3 different clients through kamailio to my backend server - see only one TCP connection is used, which I do not want. I have gone through the core modules to see if any TCP config param exists to control on this, but couldn't find one. Could anyone help how to achieve different TCP connections to same destination in kamailio? thanks, raj

Re: [SR-Users] authentication using auth_db
by arish haque 21 Apr '19

21 Apr '19

Hi David, This can solve the issue but depth(records) of that view would be too much. The architecture is like this: One kamailio fronting multiple asterisk. Each of asterisk boxes have their Specific users databases. Thus, I'm trying to create db connections inside request route or completely write my own authentication service if I get the user's Password. So, that would be great if I would be able to pass the db_url to auth_db module in request route. Let me know what you think. Thanks, Arish

Re: [SR-Users] authentication using auth_db

Hi David, Thanks for the reply. I checked out sqlops module, this will solve the problem only when I get the authentication password (secret) of the user inside request route. For this I tried checking kamailio pseudovars but haven't found one. Therefore, I am sticking with auth_db module.If this is possible by any other way do let me know. thanks, Arish

auth by IP

Following code snippet from default kamailio.cfg never gives 403 if you smart enough to set "fromdomain" parameter on Asterisk to Kamailio's IP. How to fix it? I want password-based registration (which is OK now) and permit calls via Kamailio only from permitted IPs. # if caller is not local subscriber, then check if it calls # a local destination, otherwise deny, not an open relay here if (from_uri!=myself && uri!=myself) { sl_send_reply("403","Not relaying"); exit; }

Microsoft Direct Routing Assistance And Kamailio Integration
by Phillip Cooper 18 Apr '19

18 Apr '19

Hi All, I am looking for some assistance on setting up Microsoft Direct Routing with Kamailio as an SBC. I have a partial config working, I have rewrote the headers going to Direct routing and can place calls in to and out of Direct routing. I have problems with Call hang ups and choppy audio only on the audio stream from Direct Routing. 1) place a call in to direct routing, Hang the call up from the caller and Direct routing hangs up the call. But If you place a call in to Direct routing and hang up the call from direct routing the direct routing hangs up but the call is still active on the caller. IF you call from direct routing through kamailio to a callee and hang up from direct routing the call is hung up correctly. 2) on some calls made to or from direct routing, the audio stream coming from direct routing is sometimes choppy. Its always the audio from direct routing never the audio going to direct routing. My set up: Asterisk <-> Kamailio <-> Direct Routing SIP: Asterisk <-> Kamailio <-> direct routing RTP: Asterisk <-> Direct Routing Kamailio is rewriting the R-URI, TO, FROM, Contact headers going to Direct routing, as Microsoft need the sbc hostname to be in the contact header in a particular format. I am looking for help on the above or if someone would be kind enough to provide a working config that would be awesome! :) Many Thanks in advance for assistance. :) Phil --- This email has been checked for viruses by AVG. https://www.avg.com

authentication using auth_db module
by arish haque 18 Apr '19

18 Apr '19

Hi all, I'm trying to establish mysql database connection inside request route (at runtime) based on the type of user, as credentials are stored in multiple databases (may be different servers) for the users. Therefore, I am trying to find out that is there anyway to connect to mysql dynamically in request route or pass 'db_url' parameter dynamically to auth_db module. Hope this explains the requirement. Looking for suggestions. With Regards, Arish

Hello all, Kind of a weird question: is it possible to get a config file AFTER it’s been parsed? I.e: after it’s skipped all non-defined blocks, after substdef have been applied, etc. In the form of a normal config file Is this possible? -- DVG -- Imagination is more important than knowledge Albert Einstein

Does Kamailio provide any API for other program to create sip account
by Gaurav Bmotra 18 Apr '19

18 Apr '19

Hi i am Gaurav I am developing a sip VoIP app in Android, which want to provide the feature of allowing user to create sip account from client side. I use Kamailio as sip server. My thought is when user register to the the user account system, the user account system can communicate with Kamailio, create a sip account associated with the user and pass the sip account to the client, the client then can configure itself using the sip account. Does Kamailio provide any API or module for me to do this? Thanks! -- *Regards:* Gaurav Kumar

VRF routing with kamailio 5.2
by Jonathan Hunter 18 Apr '19

18 Apr '19

Hi All, Hope everyone in community is well. I was wondering if anyone could let me know if VRF is supported with kamailio 5.2 ? Essentially I am looking to put kamailio between two SBCs and bridge the networks together. So currently Server A 1.1.1.1 connects to Server B 2.2.2.2 and they pass calls fine, and I want to add kamailio in between without changing any IPs, so using VRF I have one network interface intA with 1.1.1.1 and the other intB with 2.2.2.2. What I want to do is listen on both interfaces, which is fine but bridge or force traffic between the two. Is this possible with kamailio? As doing force socket and listening on both 1.1.1.1 and 2.2.2.2 kamailio just loops and routes to itself, and force socket doesnt help. Do you have any suggestions? Would running two instances of kamailio on same server help or even introducing to separate kamailio instances and force routing between the two for requests. I am currently just testing with SIP OPTIONS and it is already proving tricky. Any help or comments appreciated. I appreciate this might not be the best solution however we have a lead time with providers to make changes which are proving quite slow and impractical so just trying to work a solution. Thanks Jon

Via shows wrong protocol of Kamailio
by Andrew Chen 18 Apr '19

18 Apr '19

Hi all, Got another anomaly in 4.1.5. I have this block of code which does t_relay_tcp: if ($var(isTpgw) == 1) { xlog("L_INFO","[$ci][$mi][CSeq $cs] isTpgw = $var(isTpgw)"); if (!t_relay_to_tcp()) { xlog("L_INFO","[$ci][$mi][CSeq $cs] $ua Relaying [$rm] from ($si) to ($rd) via tcp....Error...\n"); t_on_failure("DISPATCHER_FAIL"); } else { xlog("L_INFO","[$ci][$mi][CSeq $cs] $ua Relaying [$rm] from ($si) to ($rd) via tcp\n"); } } But when I looked at my sip capture tool, it showed the Via marked by the Kam to use UDP: INVITE sip:######@<some domain>:5060 SIP/2.0 Record-Route: <sip:206.81.191.30;r2=on;lr=on> Record-Route: <sip:206.81.191.30;transport=tcp;r2=on;lr=on> Call-ID: DL9dc0c8dd93-1079779342(a)gs-3924.GSLAB.COM To: "sip:6204857@sjomaintpsg50.fuzemeeting.com" <sip:6204857@sjomaintpsg50.fuzemeeting.com> From: "LifesizeSIP" <sip:LifesizeSIP@gs-3924.GSLAB.COM:5060>;tag=DL325a9e10c7;epid=062EE468 CSeq: 1 INVITE Max-Forwards: 69 Via: SIP/2.0/UDP 206.81.191.30;branch=z9hG4bKb16b.bd6a0791c798e3c859f8608993d584ae.1;i=5611 Via: SIP/2.0/TCP 10.101.199.105:5060;rport=53272;branch=z9hG4bK-fc8090ecf8-DL 206.81.191.30 is the Kam.

"481 Dialog/Transaction Does Not Exist" after sending SUBSCRIBE with Expires: 0
by David Dean 18 Apr '19

18 Apr '19

When a client sends a SUBSCRIBE with Expires: 0, Kamailio responds correctly with a "202 OK". But then Kamailio sends a NOTIFY to the same client with "Subscription-State: terminated;reason=timeout". The client rejects this NOTIFY with a "481 Dialog/Transaction Does Not Exist". Why does Kamailio send this NOTIFY, and is there any way to fix or disable it because it's always rejected by the client? The client is IMSDroid, and Kamailio is 5.2.2 with a default configuration. Packet 1 = Client sending SUBSCRIBE with Expires: 0 SUBSCRIBE sip:X.X.X.X:443;transport=tcp SIP/2.0Via: SIP/2.0/TCP 192.168.0.21:45336;branch=z9hG4bK-670576127From: <sip:username@domain.com>;tag=1372208921To: <sip:kamailio.domain.com>;tag=c4eb72dabf44e7588b972bd3b454ea11-0cd6Contact: <sip:username@192.168.0.21:45336;transport=tcp>Call-ID: e8cffa8f-948d-eb99-69ca-c9f18bdf11a0CSeq: 1321654295 SUBSCRIBEExpires: 0Content-Length: 299Max-Forwards: 70Allow: INVITE, ACK, CANCEL, BYE, MESSAGE, OPTIONS, NOTIFY, PRACK, UPDATE, REFERAccept: application/pidf+xmlEvent: presence Packet 2 = Kamailio responding with 202 OK SIP/2.0 202 OKVia: SIP/2.0/TCP 192.168.0.21:45336;branch=z9hG4bK-670576127From: <sip:username@domain.com>;tag=1372208921To: <sip:kamailio@domain.com>;tag=c4eb72dabf44e7588b972bd3b454ea11-0cd6Call-ID: e8cffa8f-948d-eb99-69ca-c9f18bdf11a0CSeq: 1321654295 SUBSCRIBEExpires: 0Contact: <sip:X.X.X.X:443;transport=tcp>Server: kamailio (5.2.2 (x86_64/linux))Content-Length: 0 Packet 3 = Kamailio sending a NOTIFY NOTIFY sip:username@192.168.0.21:45336;transport=tcp SIP/2.0Via: SIP/2.0/TCP X.X.X.X:443;branch=z9hG4bKefe7.5f8ec435000000000000000000000000.0To: <sip:username@domain.com>;tag=1372208921From: <sip:kamailio@domain.com>;tag=c4eb72dabf44e7588b972bd3b454ea11-0cd6CSeq: 3 NOTIFYCall-ID: e8cffa8f-948d-eb99-69ca-c9f18bdf11a0Content-Length: 0Max-Forwards: 70Event: presenceContact: <sip:X.X.X.X:443;transport=tcp>Subscription-State: terminated;reason=timeout Packet 4 = Client responding to the NOTIFY with "481 Dialog/Transaction Does Not Exist" SIP/2.0 481 Dialog/Transaction Does Not ExistVia: SIP/2.0/TCP X.X.X.X:443;branch=z9hG4bKefe7.5f8ec435000000000000000000000000.0From: <sip:kamailio@domain.com>;tag=c4eb72dabf44e7588b972bd3b454ea11-0cd6To: <sip:username@domain.com>;tag=1372208921Call-ID: e8cffa8f-948d-eb99-69ca-c9f18bdf11a0CSeq: 3 NOTIFYContent-Length: 0 There are two entries in the Kamailio log: INFO: {1 1321654295 SUBSCRIBE e8cffa8f-948d-eb99-69ca-c9f18bdf11a0} presence [notify.c:1614]: send_notify_request(): NOTIFY sip:username@domain.com via sip:Y.Y.Y.Y:45336;transport=tcp on behalf of sip:kamailio.domain.com for event presence : e8cffa8f-948d-eb99-69ca-c9f18bdf11a0 ERROR: {2 3 NOTIFY e8cffa8f-948d-eb99-69ca-c9f18bdf11a0} presence [subscribe.c:497]: delete_subs(): Failed to delete subscription from memory [slot: 174 ev: sip:kamailio.domain.com pu: presence ci: e8cffa8f-948d-eb99-69ca-c9f18bdf11a0 ft: 1372208921 tt: c4eb72dabf44e7588b972bd3b454ea11-0cd6] These are the presence settings in the Kamailio config file: #!ifdef WITH_PRESENCE# ----- presence params -----modparam("presence", "db_url", DBURL)modparam("presence", "send_fast_notify", 0) # ----- presence_xml params -----modparam("presence_xml", "db_url", DBURL)modparam("presence_xml", "force_active", 1)modparam("presence_xml", "force_dummy_presence", 0)#!endif Appreciate your help.

Rewrite private IP in SDP
by Bonjour Madame 18 Apr '19

18 Apr '19

Hello all, I am dealing with a no audio issue, phones are not even ringing. There is a private IP address in the "VIA" section of the message header of the INVITE: Via: SIP/2.0/UDP 192.168.1.25:65291 ;rport;branch=z9hG4bKPj9e3849d1981a4094a8323dad5826ec34 and in the contact too: Contact: <sip:5002@192.168.1.25:65291;ob> In the "status 100 Attempting to connect your call" from the server, I can see the public IP of the phone under received: Via: SIP/2.0/UDP 192.168.1.25:65291 ;rport=53990;branch=z9hG4bKPj9e3849d1981a4094a8323dad5826ec34;received=PHONE_PUBLIC_IP And in the "status 200 ok" from the server, I have: Via: SIP/2.0/UDP 192.168.1.25:65291 ;received=PHONE_PUBLIC_IP;rport=53990;branch=z9hG4bKPj9e3849d1981a4094a8323dad5826ec34 Record-Route: <sip:SERVER_PUBLIC_IP;lr=on;ftag=9284528256a54f8b81e692133a15684c> I don't know what steps to take to resolve this issue.

Record route dynamic IP
by eyas barhouk 17 Apr '19

17 Apr '19

hello dears i'm trying to build kamailio & asterisk with the following : * Kamailio will listen to All the interfaces : listen=udp:0.0.0.0:5050 listen=udp:0.0.0.0:5060 * it will add the record header as in the following part : if (!isflagset(FLT_RR)) record_route(); setflag(FLT_RR); when the sip message get from kamailio to asterisk the record route header will be like "<sip:0.0.0.0:5060;....etc.>" So is there any way to make the Via and record route headers has a specific IP instead of (0.0.0.0) i mean Something like "record_route("$Ri")". thanks & regards
