[OpenSIPS-Users] Restrict Simultaneous-Use

Fri Mar 6 16:04:56 CET 2009

Hi Brett,

thanks for the hints, but doesn't work for me.
The did information in the record route header and the BYEs are there.
I also tried the other two match modes, with no success. :-(

Any idea?

Regards,
Robert

Check to be sure you really get the BYE at the end of the call.

Also take a look at the bye and see if the 'did=' is in there, if it's not (ie: if the other end UAC removes it, which it really shouldn't) then you may need to change your dialog match mode. See the dialog module docs for that.

Hi Bogdan,

now I'm currently using the svn head of opensips version 1.5.

I succeeded in pushing the channel value from the radius server into opensips by an SIP-AVP in the auth-reply. :-)

But I've got problems with the dialog profiling. Maybe I'm missing something here. At the moment I've got the following configuration for the dialog module:

----------------------------------------------------------------------------
loadmodule "dialog.so"
modparam("dialog", "dlg_flag", 4)
modparam("dialog", "profiles_with_value", "caller")
----------------------------------------------------------------------------

Following the link you told me I do the following in my invite-route after radius_proxy_authorize():

----------------------------------------------------------------------------
if (create_dialog() && set_dlg_profile("caller", "$fu")) {
       xlog("L_INFO", "created dialog/added profile");
}
xlog("L_INFO", "SIP-AVP ===> $avp(s:channels)");

if (is_avp_set("$avp(s:channels)/n") && avp_check("$avp(s:channels)", "gt/i:0")) {
       get_profile_size("caller", "$fu", "$avp(s:active_channels)");
       xlog("L_INFO", "===> User has $avp(s:active_channels) active channels!");
}
setflag(4);
----------------------------------------------------------------------------

The log statements prints "===> User has 1 active channels!" when the first invite comes in. But the number doesn't decrease when the dialog gets finished. With the next invite (doesn't matter if the previous dialog is alive), it prints " ===> User has 2 active channels!" and so forth.

Any idea what's wrong here?

Regards,
Robert

Robert,

if you do auth via RADIUS, you can push some AVPs in the reply:

http://www.opensips.org/html/docs/modules/1.4.x/auth_radius.html#id227162

The 1.5.0 is plan to be release in 2 weeks from now, if no major bugs
are discovered :)

Regards,
Bogdan

Just trying to initiate a second call when one is still up, the request is rejected (Proxy authorization fails for the new call).
