Hi, Im new to Kamailio so im sorry if some of my questions will sound a bit wierd :=) i have a setup like this: (Kamailio version 5.1) UA > Kamailio > Freeswitch Kamailio forwards registration to freeswitch without saving location. I have configured sip over websockets and im able to register to Freeswitcha via kamailio. Also, i use add_path_received() so kamailio adds a path header to register messages recv 945 bytes from udp/[192.168.50.60]:5060 at 22:38:07.283809: ------------------------------------------------------------------------ REGISTER sip:192.168.50.60 SIP/2.0 Via: SIP/2.0/UDP 192.168.50.60;branch=z9hG4bKa929.0f66d60c4333f4a3a9d83d41a63295d9.0 Via: SIP/2.0/WSS 192.0.2.110;rport=63296;received=192.168.200.77;branch=z9hG4bK6931435 Max-Forwards: 69 To: <sip:1001@192.168.50.60> From: <sip:1001@192.168.50.60>;tag=vq30modpgd Call-ID: dlnrna9o4ngn25fb9d1vi2 CSeq: 196 REGISTER Authorization: Digest algorithm=MD5, username="1001", realm="192.168.50.60", nonce="744aaa14-4a86-4ce3-b6d6-419b0a34ee90", uri="sip:192.168.50.60", response="9b592b874474d4ffe5769f2410baceef", qop=auth, cnonce="sf7ff0fp8tm5", nc=00000001 Contact: <sip:1001@192.0.2.110 ;transport=ws>;reg-id=1;+sip.instance="<urn:uuid:587f4694-7e55-46dc-a858-579a82556a20>";expires=600 Allow: ACK,CANCEL,INVITE,MESSAGE,BYE,OPTIONS,INFO,NOTIFY,REFER Supported: path, gruu, 100rel, outbound User-Agent: SIP.js/0.7.0 BB Content-Length: 0 Path: <sip:192.168.50.60;lr;received=192.168.200.77~63296~6> ------------------------------------------------------------------------ send 719 bytes to udp/[192.168.50.60]:5060 at 22:38:07.329444: ------------------------------------------------------------------------ SIP/2.0 200 OK Via: SIP/2.0/UDP 192.168.50.60;branch=z9hG4bKa929.0f66d60c4333f4a3a9d83d41a63295d9.0 Via: SIP/2.0/WSS 192.0.2.110;rport=63296;received=192.168.200.77;branch=z9hG4bK6931435 From: <sip:1001@192.168.50.60>;tag=vq30modpgd To: <sip:1001@192.168.50.60>;tag=Spya88DKU9gSQ Call-ID: dlnrna9o4ngn25fb9d1vi2 CSeq: 196 REGISTER Contact: <sip:1001@192.0.2.110;transport=ws>;expires=600 Date: Fri, 09 Feb 2018 21:38:07 GMT User-Agent: FreeSWITCH-mod_sofia/1.6.19+git~20171120T163416Z~b1b21d0695~64bit Allow: INVITE, ACK, BYE, CANCEL, OPTIONS, MESSAGE, INFO, UPDATE, REGISTER, REFER, NOTIFY Supported: timer, path, replaces Path: <sip:192.168.50.60>;lr;received=192.168.200.77~63296~6 Content-Length: 0 ------------------------------------------------------------------------ Once, registered, im trying to originate a call to the registered endpoint from freeswitch this results in an invite like this: send 1757 bytes to udp/[192.168.50.60]:5060 at 22:46:21.252549: ------------------------------------------------------------------------ INVITE sip:1001@192.0.2.110;transport=ws SIP/2.0 Via: SIP/2.0/UDP 192.168.50.65:15060;rport;branch=z9hG4bKXHcX316pDgXZB Route: <sip:192.168.50.60>;lr;received=192.168.200.77~63296~6 Max-Forwards: 70 From: "" <sip:1002@192.168.50.65>;tag=tZQ393yprj7BK To: <sip:1001@192.0.2.110;transport=ws> Call-ID: 8212b700-8885-1236-08b3-000c293ae94e CSeq: 118770326 INVITE Contact: <sip:mod_sofia@192.168.50.65:15060> User-Agent: FreeSWITCH-mod_sofia/1.6.19+git~20171120T163416Z~b1b21d0695~64bit Allow: INVITE, ACK, BYE, CANCEL, OPTIONS, MESSAGE, INFO, UPDATE, REGISTER, REFER, NOTIFY Supported: timer, path, replaces Allow-Events: talk, hold, conference, refer Content-Type: application/sdp Content-Disposition: session Content-Length: 891 X-FS-Support: update_display,send_info Remote-Party-ID: <sip:1002@192.168.50.65 >;party=calling;screen=yes;privacy=off Freeswitch appends a route header to the invite specifying kamailio as route and a received with original uri. well, here is the issue ... im failing to hit the SIP over websocket client...

Hello, before t_relay() you can't see what is going to the network, because some headers are added when knowing target address and local socket (e.g, Via, Record-Route). You can use onsend_route for seeing the request just before writing to the network. https://www.kamailio.org/wiki/cookbooks/devel/core#onsend_route $snd(buf) will give outgoing buffer -- for more see $sndfrom(...) and $sndto(...) vars.

Request Timeouts
by Wilkins, Steve 13 Feb '18

13 Feb '18

Hello, This is actually a follow up to my last question about some providers calls being dropped. I noticed that when calls are dropped, I see a Kamailio log message "Request Timeout" about 5-10 seconds before the call is dropped. I am wondering what could cause this while a call is in progress. Does Kamailio need to respond to Asterisk with a '200 OK' for an INFO request sent to Kamailio from Asterisk? I am not sure what else could cause this call dropping behavior. Note: It does not appear to be caused from a missing 'ACK'. Thank you, -Steve

What is the mechanism used for sending push notification from Kamailio, For both IOS and Android?
by Arun NV 13 Feb '18

13 Feb '18

I am creating custom phone client, which uses *Kamailio *as a proxy and it's required to send *push notification* from *Kamailio *to the clients when a call towards the client reached on *Kamailio*. I found a module for APNS here* https://github.com/tvntsr/push <https://github.com/tvntsr/push>*. But I am developing both Android and IOS clients. So What mechanism I can use for the Android side? Is there any module available for *GCM*(Google Cloud Messaging) in Kamailio? Thank you, Arunbalan

is_audio_on_hold() doesn't support rfc3264
by Julia Boudniatsky 13 Feb '18

13 Feb '18

FYI, After some tests found, that function "*is_audio_on_hold()*" (textops) *supports only rfc 254*3, where "hold" is indicated by setting the "c" destination addresses for the media streams to zero (0.0.0.0). The newest *rfc3264*, where "hold" is indicated by a=sendonly/inactive, *is not supported*. Kamailio version 4.4.6. Best regards, Julia

Very inconsistent calls
by Wilkins, Steve 12 Feb '18

12 Feb '18

Hello, I have found that calls are very inconsistent. I use Kamailio 5, Asterisk 14. When certain Providers like (Sorenson, ZVRS) make calls into a WebRTC client (tryit-jssip), sometime the calls stay up until I close them (10-15 minutes), others times those calls drop in 30 seconds. This is extremely confusing...does anyone else experience this type of behavior? -Steve

t_suspend usage in branch_route
by Aymeric Moizard 09 Feb '18

09 Feb '18

Hi, I'm trying to use t_suspend in my kamailio.cfg from a branch_route. I'm using kamailio 5.1.1 on debian jessie from http://deb.kamailio.org/kamailio51 >From the documentation: http://www.kamailio.org/docs/modules/5.1.x/modules/tmx.html#tmx.f.t_suspend i can see that "This function can be used from ANY_ROUTE ." However, the INVITE is still forwarded for this branch. So obviously the "outgoing transaction" is not suspended. May be "t_suspend" is only suspending "incoming transactions"? I tried to call "drop()". This prevent the INVITE from being sent. But in such case, i have an answer is sent immediatly to the caller (SIP/2.0 500 I'm terribly sorry, server error occurred (6/SL)) I want the script to wait as expected after my "t_suspend". And in the block indicated by t_continue, i want to append a new branch. Any way to do this? Otherwise, do you advise me to control the list of branch before t_relay? I guess I can access the list. Not sure how.. so if you have any tips... Tks Aymeric -- Antisip - http://www.antisip.com

Regular exepression issue in permissions module

Hi list, I'm testing permissions module with kamailio 5.1.1 and I was struggling with regular expressions in trusted requests part of module. I noticed that 9[0-9]{4} doesn't work as expected so I had to change it for 9[0-9][0-9][0-9][0-9] to work. Is it supposed to be like that? Is there other way in this module to simplify the expression since it is not accepting the POSIX way?

Hello All, I am running Kamailio 5 and using Asterisk 14 as PBX. I have a strange issue. When I receive calls from some providers to a WebRTC client, calls hang up after about 25 seconds. This does not happen with all providers and does not happen with WebRTC client to WebRTC client calls. It appears the "BYE" is coming from Kamailio. Any ideas? Thank you, -Steve

dmq_usrloc - which server?
by Alex Balashov 07 Feb '18

07 Feb '18

Hi, The Socket parameter of location entries is not replicated under dmq_usrloc. To make matters worse, the technical characteristics of the registrar module are such that I cannot straightforwardly modify the incoming Contact to add a rider indicating the server on which the register was received. The AoR domain is the same for all registrations received on any server in the DMQ mesh. To reach the registrants, I need to forward the registration to the correct server that corresponds to the true provenance of the registration. What is a reasonable way of finding out what that is? I don't see any method of injecting such values into the replicated contacts, as dmq_usrloc does not provide hooks for this.

any interest in segmentation fault at startup ?
by Jean Cérien 07 Feb '18

07 Feb '18

Hi I guess I'm a bit too creative when it comes to kamailio syntax.... just edited the cfg file and got the following error upon startup: kamctl start INFO: Starting Kamailio : /usr/sbin/kamctl: line 1915: 5294 Segmentation fault $OSERBIN -P $PID_FILE -f $ETCDIR/kamailio.cfg $STARTOPTIONS > /dev/null 2> /dev/null ERROR: PID file /var/run/kamailio.pid does not exist -- Kamailio start failed I assume it is my syntax in cfg that creates this, I just need to correct it, but if there is interest, I can provide the faulty cfg file J.

Re: [SR-Users] Blind Transfer WS Error

Dear Kamailians, does anyone have any idea on the issue below? Alessio told me that is always reproducible, and he can also provide captures and more logs. Thanks in advance! Matteo *From: *sr-users <sr-users-bounces(a)lists.kamailio.org> on behalf of Alessio Miranda <smirolandia(a)gmail.com> *Reply-To: *"Kamailio (SER) - Users Mailing List" < sr-users(a)lists.kamailio.org> *Date: *Tuesday, 16 January 2018 at 14:18 *To: *"sr-users(a)lists.kamailio.org" <sr-users(a)lists.kamailio.org> *Subject: *[SR-Users] Blind Transfer WS Error Hi, I have a problem with the blind transfer via WebSocket, debugging from the browser we see that in some cases when the REFER is done and the sip message "202 Accepted" arrives, the message "180 Ringing" arrives first and then the "100 Trying" and the transfer goes in error with "500 JsSIP Internal Error" I have an architecture with Kamailio in frontend and asterisk in backend on the same network, the sip dialogue between FE and BE is in SIP / UDP. The WebRTC client connects to WebSocket at Kamailio's public address. We have verified that the sip messages exchanged between kamailio and asterisk are always correct.

by Wilkins, Steve 07 Feb '18

Hello All, Contact and Record-Route are using Private IP Address - is this correct? I though the Public IP should be used. I do not know what setting is causing this to happen. Does anyone have any ideas? Thank you, -Steve

Info: Markus Monka replacing Marcus Hunger in management group
by Daniel-Constantin Mierla 07 Feb '18

07 Feb '18

Hello, Markus Monka has just replaced Marcus Hunger in Kamailio project management group. Marcus (still at sipgate) has moved to work more on frontend applications than backend, no longer interacting with Kamailio project. Markus Monka has managed the VoIP operations at sipgate for more than 15 years, helping the project over the years with various resources, mainly in respect of organizing events and testing infrastructure, sipgate being one of the oldest VoIP services using Kamailio (since first releases of SER). The change is reflected now on the website: * https://www.kamailio.org/w/management/ Warm welcome to Markus and many thanks to both of them for what they did so far for Kamailio project!

Info: Kamailio project administration updates
by Daniel-Constantin Mierla 07 Feb '18

07 Feb '18

Hello, after several discussions at some of the past IRC devel meetings, finally we started to build a team to be involved more actively in the administration of Kamailio. The project has grown steadily, not only in terms of code, but also packaging, continuous integration, social networking interactions as well as participation to events world wide. For a better coordination and ability to handle related tasks, I invited the most active developers and community members to join so called Kamailio Administration Team, the initial details about it are published as part of management page on kamailio.org: * https://www.kamailio.org/w/management/ Some more details about its rules and purpose: * https://www.kamailio.org/w/kadmin/ It will still take some time to get it properly rolling, more or less now looking to see if the community has suggestions/improvements on what can be done in these aspects. I wrote to all mailing lists for the initial announcement, but you can just reply to sr-users, if you are subscribed there, otherwise it's fine to write back to any of the lists.
