Can you try uac_req_send() from UAC module ? http://www.kamailio.org/docs/modules/1.5.x/uac.html#id2467913

Another option to initiate requests is via MI. TM module exports a mi command for this purpose: http://kamailio.org/docs/modules/1.5.x/tm.html#id2531975

Hello all

How can i generate an INVITE from OpenSER. That means that Openser
make the role of UAC.
Who have an idea for this pb.

Thanks

I will have to generate an INVITE later on so i am using this topic to ask you something. I'm working on having in one side a sequence (BYE + (re-INVITE+ newSDP)). The new SDP will have some more media parameters than the initial one.

I have been reading documentation, and it seems there is an issue to generate a bye, by using :

dlg_bye(side) function from dialog module or uac_req_send() from uac module. I've been trying to use these functions in Kamailio.cfg but it doesn't generate any bye at all on wireshark trace !!

Using dialog module : Informations about caller, callee, callid are well stored into the DB but When i am calling : dlg_bye("callee") no BYE is send to the callee...

note that this function works only for established dialogs -- so you have to track the call with dialog module.

Using uac module : $uac_req(method)="BYE"; $uac_req(furi)="sip:bob@10.10.10.2" $uac_req(turi)="sip:alice@10.10.10.2" uac_req_send();

to execute one of these functions i puted them in route[66] with a xlog line and using rtimer module to be sure it is well executed. xlog line is executed but no BYE on wireshark :s

Probably the filter is not right. Watch all the network interfaces you have.

About the INVITE+SDP :

Is it possible to generate an INVITE from the cfg file ? will uac_req_send() can have a body on his method? i guess no !!

You can have a body with the uac_req_send(), see the readme of the uac module. But probably won't help you much, since kamailio does not handle media.

Cheers, Daniel

The only way i found to generate INVITE+SDP is to use MI commands from tm module : t_uac_dlg !! am i right ?

Best regards,

Hi, I've been trying to track established call to use dlg_bye("callee") function. It works but i had to track it with : if (dlg_get("callID", "from_tag", "to_tag") and has you know call ID f_tag and t_tag are changing every time a call is established.So i would like to know how can i track a call dynamically ?

I've been trying to play with set_dlg_profile("caller", "$fu") but i don't get the point of this function..

You need to pick some constant that doesn't change, or changes in ways that are appropriate to the sort of matching you would like to do. $fu (the From URI) is just an example. It is likely you have no use for the From URI whatsoever in your tracking, so pick something else.

The point of the function is to associate the current dialog with a profile.

Think of a profile as a "container" of dialogs open at any given moment that have a common characteristic; they are united by the profile. The profile name is statically set in the configuration.

In most applications of profiles, you cannot anticipate the appropriate profile criteria. For example, you could create a profile called "globalcalls" and just put all calls going through the system in it. But, if you'd like to be able to count only calls initiated by a particular user, you'd have to use a "key" within that profile - this is like a FROM clause in an SQL SELECT statement.

The second argument to set_dlg_profile() is the key. So, for example, if you have a custom header that contains an account ID for a user, say:

X-Account-ID: 4

Then, you can use that account ID as a key:

set_dlg_profile("callsperaccount", "$hdr(X-Account-Id)");

Then, when you want to see how many calls are up for account ID X, use get_profile_size() with a specific key value:

get_profile_size("callsperaccount", "4", "$var(s:calls_up)");
