Kamailio push for Android VoIP Application and VoIP Contacts update

by sscc

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

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

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

Kamailio core dumped

by Alexey V. Panfilov

Hi there, I've kamailio 4.2.3 (i386/freebsd) which works perfectly with 200-300 cps for years. Now I need migrate to freebsd amd64. I've installed kamailio 4.4.5 (amd64/freebsd), copied kamailio.cfg, made a test call - it was all right. But when I start work load (200-300 cps), kamailio core dumped and exited.

Topoh module & call leg/transaction does not exist

by Olli Attila

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? Cheers, --Olli
