Re: [SR-Users] Using SIP tools through Kamailio and Asterisk - chrome issue.
by otron2016＠gmail.com 29 Nov '17

Through Firefox likely means via websockets (wss) rather than via the sip port. Many things could interfere with the latter. Take heart, though: websockets is harder to set up so you're likely through the worst. Look at logs and see what iftop shows you about traffic on the server as you try to make sip connections. Also try your sip client with a known-good sip server (e.g. Iptel) just to make sure the problem isn't with the client. -------- Original message -------- From: "Wilkins, Steve" <swwilkins(a)mitre.org> Date: 11/28/2017 6:39 AM (GMT-08:00) To: "Kamailio (SER) - Users Mailing List" <sr-users(a)lists.kamailio.org> Subject: [SR-Users] Using SIP tools through Kamailio and Asterisk - chrome issue. Has anyone seen the issue where, when using a sip tool and going from Kamailio to Asterisk, that audio and video won’t work, yet it works fine through Firefox? I am almost sure this not an issue with Kamailio, but I am pretty new to SIP and don’t know 100% for sure. Thank you

Hello, I set up kamailio cluster. dmq_usrloc works fine, but PUSBLISH and SUBSCRIBE replication not. If I make a call to first node I've got many(hundreds) PUBLISH messages from first node to first node and some messages (8 for example) to other nodes. And second xnotice in config not executes.

dispatcher/carrierroute and branches across SBC and remote peer
by Nathan Ward 28 Nov '17

28 Nov '17

Hi, We use Kamailio as a SIP server, and SEMS as an SBC. We have a need to use the dispatcher/carrierroute modules to provide HA/load sharing across two different parts of our environment: 1) Our SBCs 2) Our peer’s SIP servers We have pairs of SBCs (for now) and they have the same network connectivity - different IPs of course, but they can reach the same things. Our peer’s network has 2 SIP servers (again, for now) reachable through either SBC. We select which SBC pair to use based on where the calls are going, in a branch route. In some cases, we use parallel forking, in others we use serial forking (i.e. to a media server for a prompt, then sending the call to wherever it needs to go). Right now there is no automatic failover or load sharing, so this is all simple logic - if call is to x peer or y customer, use x SBC or y SBC. I’m trying to add the failover/loadbalancing now. I have a few half baked ideas about how to achieve a network like this, but thought I’d ask if anyone else had done this first before I went too overboard. Currently I’m thinking of calling cr_route to figure out which peer SIP server, from there figuring out which SBC pair, and then calling ds_select_dst to select which SBC in the pair to set $du. I’m being tripped up though, as I can’t call cr_route or ds_select_dst in a branch route, but, as far as I’m aware that’s where I’d need to do so in order to handle this for multiple branches. Should I be looping the request through the SIP server to achieve this (i.e. force $du = 127.0.0.1 in my branch_route), or, can I avoid that complexity? -- Nathan Ward

Kamailio didn't start before increasing fork_delay
by igor.potjevlesch＠gmail.com 27 Nov '17

27 Nov '17

Hello, We suddenly had an issue on one Kamailio instance: we were not able to restart. Kamailio started to boot and fork and suddenly crashed. The last logs reported a failure regarding the ability to connect to one MySQL instance. I finally succeed to restart after increasing: fork_delay=5000 to fork_delay=9000. How this could happen suddenly? We already restarted Kamailio on this server. Regards, Igor.

Dispatcher with kam & fs behind nat
by Daniel Greenwald 27 Nov '17

27 Nov '17

Dispatcher is sending inbound calls to Freeswitch boxes. Both the FS boxes and Kam are behind the same nat. What is the correct way to pass calls to the FS boxes so that all SIP between FS & Kam use local IP's? Should Kam put two record-route headers on, one with PUBLICIP and one with PRIVATEIP? How is this accomplished? Thanks

Re: [SR-Users] sipML5 through kamailio
by Wilkins, Steve 24 Nov '17

24 Nov '17

I just verified that I do have logging in all pertinent areas. I added tls and I do see "TLS accept successful" in the kamailio logs, however, I see no log being generated in route[xhttp:request], and I do have logging in the first line of this route. I don't think it is getting there. Also, I noticed I have event_route[xhttp:request] not route[xhttp:request]. Thank you, -Steve

sipML5 through kamailio
by Wilkins, Steve 24 Nov '17

24 Nov '17

Hello, I am attempting to use sipML5 to test WebRTC. I have not been successful in getting messages through to Kamailio though. I am running Kamailio 5.0.3 on Cento 7. My listen's in the kamailio configuration file are => listen=tcp:112.22.3.108:5060 advertise 34.226.187.61:5060 listen=udp:112.22.3.108:5060 advertise 34.226.187.61:5060 listen=tcp:112.22.3.108:10443 (which I will use in the sipML5 Expert mode) My sipML5 settings are => Public Identity - sip:user1@112.22.3.108 Realm - 112.22.3.108 Export mode setting are => WebSocket Server URL - wss://112.22.3.108:10443 (I have also tried wss://112.22.3.108:10443/ws) SIP outbound Proxy URL - udp://112.22.3.108:5060 (I have also left this blank) When I make a call I see no Kamailio activity (I have logging at the start of request_route) so I am not sure where the configuration error is. If I change the sipML5 configuration IP Address to use the asterisk IP Address, sipML5 works. My goal is to go WebRTC Client => Kamailio => Asterisk and eventually through some sort of media proxy. Thank you, -Steve
