Access avp between sip transactions
by Grant Bagdasarian 09 Mar '17

09 Mar '17

Hi, Is it possible to access an avp variable from a different sip transaction? On an INVITE is set an avp, but on ReINVITE I would like to access this avp again and get the value. Currently the value is null, which makes sense. Not sure if this is possible and if it violates any rules inside the Kamailio engine? I guess I could use a htable, but I'm just wondering if there is a built-in way for doing this. Regards, Grant Bagdasarian CM

Kamailio Presence help required.
by SamyGo 08 Mar '17

08 Mar '17

Hi, I'm in need of making/tweak an existing Kamailio Presence setup which is giving some tough time. *Whats already working:* BLF dialog states changes are already sent across the users. SCA is working as well. *What isn't working:* When a User comes online then it sends SUBSCRIBE with *Event: dialog* and don't get notified of its subscribers state right then unless the monitored extensions make a call (BLF works) *Why is it not working:* As evident from wireshark traces, the user IP phones (Test sets: Polycoms, Yealink, CISCO, Grandstream) don't send our *Event: presence* rather only *Event:dialog* and Kamailio do not send NOTIFY out to everyone. Though yes there is an internally generated PUBLISH seen and handled properly upon registration state changes. Jitsi has been tested and Kamailio send out these registration state change info to jitsi, somce jitsi sends *Event:presence *in SUBSCRIBE. I need dialog based NOTIFY to be sent out on registration state-change. Need pointers and help on the topic, looking forward to some feedback. Regards, Sammy

TCP stack is not doing load distribution among children
by Surendra Pullaiah 08 Mar '17

08 Mar '17

Hi Daniel, Thanks for your suggestions. The approaches which you have suggested are good, event I thought before initiating this query (since am working with kamailio for last three years), but my requirement is to distribute on single connection. Since it requires code change, started working on it. Really thanks for understanding my concern. @juha: Dear juha, it is not broken TCP implementation, kamailio TCP stack well implemented. If you would like to build a server to handle HTTP and MSRP protocols at higher rate, here is the place. But for SIP we have options to handle either UDP/TCP. Thanks surendra

Kamailio push for Android VoIP Application and VoIP Contacts update
by sscc 08 Mar '17

08 Mar '17

good day, i have a running kamailio server having 200 users. I maintain the user ids in a vcf (vCard Format) form. i have developed an Android VoIP application. Android application is given to the user along with the contact vcf. The contact list get increased day by day and consequently the user ids in vcf (vCard Format) as well. the application is also updated. Aim is to update application and the contact list by sending push notification to user. (we don't want to place our application at play store). i want to do push notification from Kamilio server for application and contact list update. Is there any way to do push notification from server to users to update the app and VoIP contact list. regards sscc -- View this message in context: http://sip-router.1086192.n5.nabble.com/Kamailio-push-for-Android-VoIP-Appl… Sent from the Users mailing list archive at Nabble.com.

TCP stack is not doing load distribution among children for SIP
by Surendra Pullaiah 08 Mar '17

08 Mar '17

Dear Daniel, A small concern in kamailio, existing TCP stack is not doing load distribution among children for SIP messages. For example UE-->kamailio1 (TCP listen (4 children)) ----->kamailio2 (TCP Listen 4 children) As per stack if UE opens a connection with kamailio1 based on free children it is sharing the FD, so no problem towards from UE to kamailio1, then need requirement to forward same sip message to kamailio2, here kamailio1 is opening connection with kamailio2 and then forwarding. Suppose if we forward two requests to kamailio2, only one children is getting used among four. With this design suppose if we want to run our kamailio as two sip servers we may not achieve good results when performance matters. Please suggest something on this to move further. Regards surendra

new keepalive module ?
by Guillaume Bour 07 Mar '17

07 Mar '17

Hi all, I would like to implement destinations keepalive in drouting module (as it is done in dispatcher). But instead of duplicating what's implemented in dispatcher, I think it would be more clever to create a new module dedicated to pinging destinations, and to plug drouting, dispatcher and other modules to this new one What's you opinion about that ? Cheers, Guillaume

Topoh module & call leg/transaction does not exist
by Olli Attila 06 Mar '17

Hello, I recently started testing topology hiding module on Kamailio and encountered a problem where B party hangs up, Kamailio can't identify the ongoing transaction to which the BYE should be related to and instead of tearing the call down Kamailio just sends back "481 Call leg/Transaction does not exist" to B party. On Kamailio config I have only enabled the topoh.so -module with default options and configured this to enable masking: modparam("topoh", "mask_callid", 1) Here is what the INVITE to B party looks like and the BYE message coming from the B party: http://pastebin.com/raw/f63zUmid When debugging on Kamailio end i get: http://pastebin.com/raw/ZefGAz30 Is this a Kamailio issue or a softphone issue on B party end?

sip over websockets sip uri
by Jade SZ 28 Feb '17

28 Feb '17

Hi Team, Question: Just wanted to clarify regarding SIP URI in webrtc (over sip) connection. e.g. if we have a scenario where Kamailio is hosted with websocket support. Websocket URI is used to send packets to to wss/ws address and the SIP URI goes with it. I have tested it with any SIP URI including any domain and it works if I authenticate that domain, regardless that domain is real or not. // client side SIP URI config var configuration = { uri : 'sip:alice@example.com', }; Can we use any central domain for sip uri similar to realm concept and send traffic to multiple kamailio servers through websocket LB. dummy.domain - for ws/wss SIP URI kamailio-a.domain.com kamailio-b.domain.com Thanks in advance.
