180 and 183 SIP messages
by Ali Taher 30 Mar '18

30 Mar '18

Hello everyone, I'm working on freeswitch , where I have SIP calls coming from A-Party to my freeswitch and I'm routing it to B-Party. I'm facing an issue , when I'm getting back the 183 message from the supplier(B-Party) and forwarding it to the customer(A-Party); the customer is not hearing the RBT and asking to send 180 rather than 183 . (the supplier is only sending 183 without 180). Is it possible using kamailio to replace this 183 message with 180 message , or even add 180 message while keeping the same 183 message ? Regards, Ali Taher

kamailio & vmware
by Jean Cérien 29 Mar '18

29 Mar '18

Hello We are running a kamailio 5.0 on a VMWARE / VSPHERE 6.0 vm, with a couple of asterisk running on 2 physical hosts. Audio goes straight to the asterisk, no rtpengine / rtpproxy. I actually have no audio issues, but communication between the asterisk & kamailio for sip sometime fails - I get a few 408. I cant tell if this is network related or virtualisation related. Anyone has advice on kamailio on a VM, when it only handles sip ? Rgds J.

Kamailio to Asterisk Proxy with NAT
by Benjamin Marty 29 Mar '18

29 Mar '18

Hello, I have multiple Asterisk Servers in a private Network. They also have a Public IP via Destination NAT. Now I want to use a Kamailio Proxy in front of them. The Routing I want to do with the Kamailio Dispatcher module. My Question is now how the RTP Media Stream should/can flow. The clients are in different other networks. So P2P Media Stream isn't possible. Should I now run the RTP Stream Client - Asterisk or Client - Kamailio - Asterisk? Is there an Example for an such scenario? Thanks Benjamin

Missing exit function on KEMI?
by Enrico Bandiera 29 Mar '18

29 Mar '18

Hello, I'm trying to use the KSR.x.exit() function in a KEMI python script but at runtime i get this error: KSR.x.exit() AttributeError: 'module' object has no attribute 'exit' It seems that the exit function is missing even though it is documented. My kamailio version is: kamailio 5.2.0-dev4 (x86_64/linux) (it's a nightly) Any idea on what I can do? Thanks, Enrico.

Kamailio NAT AWS EC2
by Benjamin Marty 29 Mar '18

29 Mar '18

Hi, I am new to Kamailio and coming a bit from the Asterisk side. My goal is to set up a bunch of users on a Kamailio Instance on AWS EC2 and get them able to call each other and talk to each other over the Internet without P2P media stream. Is rtpproxy the tool that enables that? As far my knowledge is right Kamailio isn't able to do any sort of RTP handling. Regards, Benjamin

28 Mar '18

Hi. New to the area of Kamailio. i am did install in debian kamailio with rtpproxy and i have created 3 users 1000-10002 (one for each jitsi user) they talk nice between them. I have followed this tutorial http://kb.asipto.com/kamailio:skype-like-service-in-less-than-one-hour and in less than 5 minutes i had my accounts registered. i would like to have a media server so the users could hears announcements and stuff. At the end i would like to have kamailio as a test lab PBX where i could connect my SIP trunk providers and my users to route calls. Is there any guide on how to setup a media server and the services, please?

is t_flush_flags() really needed?
by Juha Heinanen 28 Mar '18

28 Mar '18

While testing xflags, i noticed that a regular flag that I set AFTER calling t_newtrans() stays set in onreply_route even when I do not call t_flush_flags(). In a route block: if (!t_newtran()) { ERROR(Failed to create new transaction for $rm <$ru>); exit; }; if (!isflagset(19)) INFO(******** flag 19 is NOT set after t_newtran()); setflag(19); and in onreply_route: if (isflagset(19)) INFO(********* flag 19 is set); else INFO(********* flag 19 is NOT set); Syslog gets: Mar 25 11:24:41 trout /usr/bin/sip-proxy[21362]: INFO: ******** flag 19 is NOT set after t_newtran() Mar 25 11:24:41 trout /usr/bin/sip-proxy[21433]: INFO: ********* flag 19 is set So what is the point of t_flush_flags()? -- Juha

Terminate dialog from another dialog
by Joel Serrano 27 Mar '18

27 Mar '18

Hi guys, I'm trying to set kamailio to not allow simultaneous calls from the same user, but if a second call comes in, the behavior desired is to process that second call and terminate the previous (already active) one. Say you have call A that creates dialog A. Then you have call B come in, creates dialog B. Can I save some info from dialog (call) A in a htable for example, then check that htable for the needed info from dialog (call) B and terminate dialog (call) A if it exists? I think using dlg_get() and dlg_bye() would do the trick but not 100% sure how they work.. The example in the docs seems exactly the case: dlg_get --> "Search and set current dialog based on Call-ID, From-Tag and To-Tag parameters" if(dlg_get("abcdef", "123", "456")) { dlg_bye("all"); } After the dlg_get() and dlg_bye() what happens to call B? Does the route continue running or does it end? Will it automatically switch back to the current dialog or do you have to manually switch back running dlg_get() again? (Sorry if I'm not explaining myself correctly, let me know if it sounds confusing) Does anyone have experience with these two functions? Thanks, Joel.

kamailio 5.0.6 try to using dialog module - dont starts dialog counting
by Karsten Horsmann 27 Mar '18

27 Mar '18

Hello, i try to get dialog-infos to see how many calls are running on my kamailio. But i can not figure out what steps are necessary to get this running. loading the module and the dependencies - check. set and dlg_flag via module param - check. MUST i use a DB?! Or what is missing? kamctl stats | grep dialog "dialog:active_dialogs = 0", "dialog:early_dialogs = 0", "dialog:expired_dialogs = 0", "dialog:failed_dialogs = 0", "dialog:processed_dialogs = 0", the dialog snippets (grep out ouf my config): #!define DLG_FLAG 8 loadmodule "dialog.so" modparam("dialog", "dlg_flag", DLG_FLAG) modparam("dialog", "dlg_match_mode", 1) modparam("dialog", "rr_param", "did") modparam("dialog", "profiles_with_value", "active_calls; inbound_calls; outbound_calls") modparam("dialog", "send_bye", 1) modparam("dialog", "enable_stats", 1) modparam("dialog", "dlg_extra_hdrs", "Hint: inactivity timeout\r\n") # Added to requests generated locally by the module (e.g. BYE) modparam("dialog", "track_cseq_updates", 1) -- Kind Regards *Karsten Horsmann*
