Is this idea even feasible?
by Antony Stone 04 Nov '21

Hi. I'm looking for a solution to the following problem, and wondering whether Kamailio (with which I have very little experience so far) may be it, or whether I'm thinking in totally the wrong direction. The problem: I have a SIP client application which runs on a standard Linux system, and is extremely basic - it can REGISTER in order to receive inbound calls, and it can send INVITEs in order to place outbound calls, and that's about it. It handles media as well - in essence, it's a simple softphone. I can't change it for a more capable one, before anyone suggests that :) Specifically, this thing cannot send REINVITEs in order to put calls on hold, nor can it handle anything to do with transfers (blind or attended). I'm looking for something which does have these SIP capabilities which I could put in between this application and the SIP server through which it is placing and receiving calls, so that I can (through some sort of API) cause calls in progress to be put on hold, resumed, blind transferred, or hold-and-attended- transferred. Does that sound like something Kamailio can do? If so, can anyone point me in a helpful direction re how to go about it? If not, can anyone suggest something else which could sit in between a very basic SIP client and a PBX server, in order to inject these sorts of commands into the path and thereby give me these sorts of extra call capabilities? Thanks, Antony. -- I'm not impossible, just highly implausible. Please reply to the list; please *don't* CC me.

update max_while_loops in config
by Juha Heinanen 08 Oct '21

08 Oct '21

It is possible to update value of max_while_loops dynamically in config file? For example, there could be a need to increase the max in some while loop, but after the loop is done, decrease it again for other loops. There exists an rpc command to do that, but I haven't found how to do it in config file. I tried @cfg_seti.core.max_while_loops = 200; but got syntax error. -- Juha

Sipwise SEMS
by David Villasmil 30 Sep '21

30 Sep '21

Hello guys, I know SEMS can provide conference, voicemail, and other services. In theory it’s also a B2BUA. Could I use a python script to provide a simple routing service? I.e.: receive an invite and send it somewhere else based on some routing logic? Thanks all David -- Regards, David Villasmil email: david.villasmil.work(a)gmail.com phone: +34669448337

manually append_branch to lookup result
by David Villasmil 07 Sep '21

07 Sep '21

Hello guys, I'm trying to dynamically add a branch after doing lookup. The user is found, but in some cases I need to add a branch and do parallel forking. So i'm basically doing: route[LOCATION] { if (!lookup("location")) { .... } if (something) { route(BRANCH_TO_EXTRA); } route(RELAY); } route[BRANCH_TO_EXTRA] { $fs = MY_SOCKET; append_branch("sip:$tU@" + $sel(cfg_get.pstn.gw_ip) + ":" + $sel(cfg_get.pstn.gw_port)); return; } For some reason only the branch appended is being used (I have append_branches=1) Ideas?

Manage multiple RTP streams with different TO-tags (forking)
by B. Tietz 07 Sep '21

07 Sep '21

Hello, following situation. I have a Kamailio (5.4) using rtpengine to loadbalance calls. If a call from Alice comes in, Kamailio decides to send the call to Carrier B from Bob. Bobs Phone is ringing and the carrier B send a 183 Session Progress with SDP and To-tag=abcd. The SDP has G722 as codec and port 1234. A few moments later carrier B send a second 183 Session Progress with SDP and TO-tag=fghi. The SDP has G711 as codec and port 5678. This is done, to play some funky music as ringtone -.- If Bob answers the call, carrier B sends a 200 OK WITHOUT SDP and TO-tag=abcd. So this should instruct our Kamailio to switch to the first G722 and port 1234. But sadly, this is just not working as expected. We tried to set the flags media-handover and port-latching for the rtpengine options and additionally set a to-tag when using rtpenging_manage. But this doesn't solve the codec change, so we have only audio when Bob answers the call, but no ringtone-music. If we allow G711 only in the outgoing INVITE to Bob, we have also tha ringtone-muisic, because there is no codec-change. Carrier B tells us, they are using a fork-mechanism. Is there something we can do, to support the codec change in 183? Or enforce carrier B to send SDP in 200 OK? Or anything else? Carrier B can not change anything in the ringtone-music-backend. They are stuck on G711. Thanks!

Re: [SR-Users] t_drop_replies not working with t_suspend in failure route

Hi, We’re still using kamailio 4.4 but we’ll be migrating to 5.0 soon. Cool so it will be fixed when we migrate !

And from my understanding t_suspend() adds a new branch. But is it possible that t_drop_replies() cannot be used with t_suspend()? Or am I missing something?

How to drop negative final response and send ACK
by Koray Vatansever 02 Sep '21

02 Sep '21

Hi, I have a problem with the following scenario: I have web and mobile sip clients for the same username. If both clients are idle, INVITE is forked and both clients ring. If web client is busy and mobile client is online and registered, the mobile client rings and the caller hears ringback tone. If web client is busy and mobile client is offline, before the mobile client receives push notification and registers, web client sends 486 busy response and caller hears busy tone. In this last scenario, I want to wait some time for the mobile client to register and ring. I tried to drop 486 response in onreply_route[x], but I found that final responses cannot be dropped in this route. I dropped 486 in reply_route, but I couldn't send an ACK for this transaction. Is there a way to implement this scenario? I would appreciate if you have any suggestions. Thanks, Koray
