IMS diameter server module
by Pavithra Mohanraja 28 Sep '20

28 Sep '20

Hi, could anyone please give me some inputs on ims diameter server.. How it can be used ? I tried to use ims diameter server to send http request from pcscf to pcf. But before sending http request, it is sending diameter request to pcf and it is getting failed. I need to have only http request such that my http api should be sent to pcf from pcscf.So I need some input on how it can be used. I have referred the link https://kamailio.org/docs/modules/5.4.x/modules/ims_diameter_server.html but couldnt able to get much details .. If anybody have worked on this, It would be helpful if you give some more details Thanks, Pavithra

Linphone push notifications (iOS) and kamailio
by Jan Rozhon 26 Sep '20

26 Sep '20

Hi, I know this is kind of a wrong forum for this question, but I have got no answer from linphone forum so I am trying my luck here. I have kamailio with pretty much the default config with slight modification enabling me the push notifications for iOS (via curl) and late forking (t_suspend, t_continue). But my linphone on iOS although gets awaken does not present me with the call I am trying to establish. Did anyone of you guys experimented with similar setup? If so, to what degree were you successful and can you share some insights especially on the format of push notification where I suspect my problem to be rooted? Thanks in advance and once again, sorry if I am off-topic too much. Regards, Jan

Mapping History-Info <-> Diversion headers
by Anonim Stefan 25 Sep '20

25 Sep '20

Hi guys, I am trying to map all History-Info to/from Diversion headers in a given SIP REQUEST, based on RFC 7544. I want to ask if you are aware of any module functions that does that? (e.g. something like convert_history_to_diversion() and convert_diversion_to_history()) Alternatively, I want to ask you what do you think of such module functions and in which module would they fit best? e.g. textops/tectopsx/diversion ?! Thank you, Stefan

usrloc - ka_mode timeout
by Ilie Soltanici 25 Sep '20

25 Sep '20

Hello, Is there any way to add those functions from the nathelper module to the usrloc module? *keepalive_timeoutnatping_interval* I'm looking to use ka_mode feature from the usrloc module in order to have roundtrip time computed for each extension but because those functions are missing in the usrloc module and per documentation this functionality conflicts in some way with nathelper module it's not recommended to have both modules enabled. Or maybe there is another way to have them "interconnected"? Thank you.

rtpproxy_manage and AWS
by Aymeric Moizard 25 Sep '20

25 Sep '20

Hi, I have 2 hosts on AWS behind NAT: One with rtpproxy: /usr/local/bin/rtpproxy -f -p /run/rtpproxy/rtpproxy.pid -s udp: 0.0.0.0:31500 -A 15.236.230.177 <http://15.236.230.177/15.236.230.177> -l 0.0.0.0 <http://0.0.0.0/0.0.0.0> -m 35000 -M 65000 -d DBUG:LOG_LOCAL5 -u rtpproxy:rtpproxy -F The other one, with a kamailio and using only rtpproxy_manage(); without parameters. I'm surprised because in my SDP being modified, kamailio is replacing with its KAMILIO private IP. (not the rtpproxy one) I see that rtpproxy and kamailio are exchanging data. Nothing obvious is coming out. Any obvious mistakes? Anything you need to help? Should I switch to another rtp engine? Regards Aymeric -- Antisip - http://www.antisip.com

Calling a user registered on a different kamailio
by Joey Golan 24 Sep '20

24 Sep '20

Hello, I’m trying to make a call between 2 users registered (TLS) on two different kamailio instances behind haproxy with NAT handling. UE1 is registered to kamailio1 UE2 is registered to kamailio2 DMQ and dmq_usrloc are enabled so each kamailio can see all registered users. What else do I need to do in order to make it work properly? Thanks, Joey.
