[SR-Users] hanging active dialog...

[Gertjan Wolzak]

Hello Carlos,

 

I have been looking at your module, can’t wait to work with it, especially
the prepaid part.

 

But as this system is in production, can’t just start experimenting, want
to
. But cant.

 

So just have to wait for some tips on the cli
.

 

But thanks.

 

Rgds,

 

Gertjan

I don't know what exactly happened in your case but if you don't have time
to investigate you can try cnxcc module [1] channel control to achieve the
same goal.

 

Take a look at the sample configuration file located in [2]

 

 
xlog("L_INFO", "Setting up channel based credit control");
 
 
         $var(max_chan)   = 2;
 
         $var(retcode)    = cnxcc_set_max_channels("$var(client)",
"$var(max_chan)");
 
 
         if ($var(retcode) == -1) {
 
                 xlog("Error setting up credit control");
                 return;
 
         }
 
 
        $var(count)     = -1;
 
 
        if (!cnxcc_get_channel_count("$var(client)", "$var(count)")) {
 
                xlog("Error getting customer's channel count");
 
        }
 
 
        xlog("L_INFO", "CNXCC ROUTE: $var(client) has $var(count) call(s)");
 
 
         if ($var(retcode) < -1) {
 
                 xlog("Too many channels for customer");
 
                 sl_send_reply(403, "Forbidden");
 
 
                 if (!cnxcc_terminate_all("$var(client)")) {
 
                          xlog("Error terminating customer's calls");
 
                 }
 
 
                 exit;
         }

Goodmorning All,

 

I use the following route to check for concurrent calls by the same user, if
a concurrent call is tried it is not allowed.

 

route[CONCURRENT]

{

        xlog("SCRIPT: Conccurrent call check");

 

        if(!get_profile_size("caller","$fu","$avp(nrcalls)"))

        {

                sl_send_reply("403", "Call not matching profile");

                exit;

        }

        xlog("SCRIPT: caller value for $fu is $avp(nrcalls)");

        if($avp(nrcalls)>= 1)

        {

                sl_send_reply("403", "Active calls limit exceeded");

                exit;

        }

        dlg_manage();

        if(!set_dlg_profile("caller","$fu"))

        {

                sl_send_reply("500", "No new channels in this profile");

                exit;

        }

 

        xlog("SCRIPT: caller value for $fu is now $avp(nrcalls)");

 

}

 

Now I had a situation where a user could not call because the
get_profile_size for this user gave the value 1. So another call was not
allowed.

But the user did not have a call active. As no dialogs were active, checked
that.

 

I assume there can be a lot of reasons why this happens, also I want to use
the “I don’t want to know the cause” method to solve this.

 

So I looked at the dialog module documentation, to see if I can just clear
the profile size for this specific user.

 

I wanted to use the profile_list_dlgs(8.6) to get the dialog details, then
the dlg_terminate_dlg(8.4) to, you guessed it, terminate that dialog.

 

But it’s not clear to me how I can give those commands
.

 

Is there a way to give those commands on the cli, if so can someone please
write down some examples


 

Would be really appreciated.

 

Rgds,

 

Gertjan
