Create a profile [1], and count the number of calls of that profile [2].
Alternatively, you can use cnxcc module [3].

Thank you very much Carlos !
One last thing, can I use $fd in cnxcc_set_max_channels as below - cnxcc_set_max_channels("$fd", "$var(max_chan)"); to restrict the simultaneous calls hitting a particular domain ?

Any pseudo variable should work.
I don't exactly know how your business work, but I'd suggest that instead of using from header domain, use the domain part of the request-uri, $rd.

Hello Carlos,
Many thanks for your help. I followed the steps you mentioned for CNXCC. But even after making the max. calls to 0, I am still able to connect the call. Below is the excerpt from kamailio.cfg
request_route { setflag(DLG_FLAG); # per request initial checks route(REQINIT); # NAT detection route(NATDETECT); . . .
if (is_method("INVITE")) { route(CNXCC); } }
#Below lines added by Rahul for Concurrent Call Restriction route[CNXCC] {
$var(client1) = "x.y.z.a";
#!ifdef CNXCC_CHANNEL xlog("L_INFO", "Setting up channel based credit control");
$var(max_chan1) = 0; $var(retcode) = cnxcc_set_max_channels("$var(client1)", "$var(max_chan)");
if ($var(retcode) == -1) { xlog("Error setting up credit control"); return; }
$var(count1) = -1;
if (!cnxcc_get_channel_count("$rd", "$var(count1)")) { xlog("Error getting customer's channel count"); } xlog("RAHUL : CNXCC ROUTE: $var(client) has $var(count) call(s)"); xlog("L_INFO", "CNXCC ROUTE: $var(client) has $var(count) call(s)");

exit; } #!endif
Could you please guide me where am I doing wrong ?

max_chan is equal to zero? You should put a positive value in here in order to make sense the function call.
Also, you are using for one call the ID "x.y.z.a", and for the other one $rd. Both should be the same for calls that suppose to be organized in the same group.
Please take a look at the docs.

Hi Carlos,
Sorry for coming late on this one.
the ruri value in my example is '10.97.116.36' and i have tried to configure kamailio to only cater 100 simultaneous calls on this SIP Server (10.97.116.36), after that it is to send 403.
Below is the sample logic from kamailio.cfg *********************************************************************************************************************** #Below lines to show an example of how I am maintaining the business for Concurrent Call Restriction route[CNXCC] {
$var(client1) = "10.97.116.36"; $var(max_chan) = 100; #!ifdef CNXCC_CHANNEL xlog("L_INFO", "Setting up channel based credit control");
$var(max_chan1) = 0; $var(retcode) = cnxcc_set_max_channels("$var(client1)", "$var(max_chan)");
if ($var(retcode) == -1) { xlog("Error setting up credit control"); return; }
$var(count1) = -1;
if (!cnxcc_get_channel_count("$rd", "$var(count1)")) { xlog("Error getting customer's channel count"); } xlog("RAHUL : CNXCC ROUTE: $var(client1) has $var(count1) call(s)"); xlog("L_INFO", "CNXCC ROUTE: $var(client1) has $var(count1) call(s)");
if ($var(count1) == $var(max_chan1)) { xlog("Too many channels for customer"); sl_send_reply(403, "Forbidden");
exit; } #!endif ******************************************************************************************************************************************************
Now the problem that I am facing is that with multiple UACs (all with same ruri - 10.97.116.36) dialing some pstn numbers, the value of "count1" remains 1 for all cases. Hence, my purpose is defeated because the restriction is not being laid and more than 'max_chan' no. of callers are able to make the call.
Could you please help me achieve this goal.
Thanks !

Hi Rahul,
I don't understand your example. In that case, you are always using "10.97.116.36" as key, meaning that all calls will be hanging from same root.
If you want to use the request-uri domain part, use $rd, not the full $ru. This will of course lead to 1 call being reported always, since request-URIs tend to be different from each other.
Regards, Carlos

Please take a look at the docs.

One last thing, can I use $fd in cnxcc_set_max_channels as below - cnxcc_set_max_channels("$fd", "$var(max_chan)"); to restrict the simultaneous calls hitting a particular domain ?

HI Carlos,
Thanks for reply.
In my case the key is SIP Server IP. My kamailio Proxy is connected to many sip server IPs say 5. I want to limit maximum channels per sip server ip. So I set max channels per sip server ip as cnxcc_set_max_channels("$var(client1)", "$var(max_chan)"); and my $var(client1) = "10.97.116.36"; is one of 5 sip servers connected to Kamalio.
Now I use your cnxcc_get_channel_count("$rd", "$var(count1)")) value(count1) to compare to the max_limit of the channels allowed for this sip server. Psuedo Variable $rd is coming correctly that is same as sips erver IP[$var(client1)]. But the problem is that cnxcc_get_channel_count("$rd", "$var(count1)")) is always setting the value 1 in $var(count1) variable even though there are more calls runnning than what was set to be max_chan (which was 100 in my case).
Any pointers to achieve this matter ?

Hi Rahul,
I don't understand your example. In that case, you are always using "10.97.116.36" as key, meaning that all calls will be hanging from same root.
If you want to use the request-uri domain part, use $rd, not the full $ru. This will of course lead to 1 call being reported always, since request-URIs tend to be different from each other.

Hi Carlos,
Sorry for coming late on this one.
the ruri value in my example is '10.97.116.36' and i have tried to configure kamailio to only cater 100 simultaneous calls on this SIP Server (10.97.116.36), after that it is to send 403.
Below is the sample logic from kamailio.cfg
#Below lines to show an example of how I am maintaining the business for Concurrent Call Restriction route[CNXCC] {
$var(client1) = "10.97.116.36";$var(max_chan) = 100; #!ifdef CNXCC_CHANNEL xlog("L_INFO", "Setting up channel based credit control");

if ($var(count1) == $var(max_chan1)) { xlog("Too many channels for customer"); sl_send_reply(403, "Forbidden"); exit; }#!endif
Now the problem that I am facing is that with multiple UACs (all with same ruri - 10.97.116.36) dialing some pstn numbers, the value of "count1" remains 1 for all cases. Hence, my purpose is defeated because the restriction is not being laid and more than 'max_chan' no. of callers are able to make the call.
Could you please help me achieve this goal.
Thanks !

HI Carlos,
Thanks for reply.
In my case the key is SIP Server IP. My kamailio Proxy is connected to many sip server IPs say 5. I want to limit maximum channels per sip server ip. So I set max channels per sip server ip as cnxcc_set_max_channels("$var(client1)", "$var(max_chan)"); and my $var(client1) = "10.97.116.36"; is one of 5 sip servers connected to Kamalio.
Now I use your cnxcc_get_channel_count("$rd", "$var(count1)")) value(count1) to compare to the max_limit of the channels allowed for this sip server. Psuedo Variable $rd is coming correctly that is same as sips erver IP[$var(client1)]. But the problem is that cnxcc_get_channel_count("$rd", "$var(count1)")) is always setting the value 1 in $var(count1) variable even though there are more calls runnning than what was set to be max_chan (which was 100 in my case).
Any pointers to achieve this matter ?

Hi Rahul,
I don't understand your example. In that case, you are always using "10.97.116.36" as key, meaning that all calls will be hanging from same root.
If you want to use the request-uri domain part, use $rd, not the full $ru. This will of course lead to 1 call being reported always, since request-URIs tend to be different from each other.

Hi Carlos,
Sorry for coming late on this one.
the ruri value in my example is '10.97.116.36' and i have tried to configure kamailio to only cater 100 simultaneous calls on this SIP Server (10.97.116.36), after that it is to send 403.
Below is the sample logic from kamailio.cfg
#Below lines to show an example of how I am maintaining the business for Concurrent Call Restriction route[CNXCC] {
$var(client1) = "10.97.116.36";$var(max_chan) = 100; #!ifdef CNXCC_CHANNEL xlog("L_INFO", "Setting up channel based credit control");
$var(max_chan1) = 0; $var(retcode) = cnxcc_set_max_channels("$var(client1)","$var(max_chan)");
if ($var(retcode) == -1) { xlog("Error setting up credit control"); return; } $var(count1) = -1; if (!cnxcc_get_channel_count("$rd", "$var(count1)")) { xlog("Error getting customer's channel count"); } xlog("RAHUL : CNXCC ROUTE: $var(client1) has $var(count1)call(s)"); xlog("L_INFO", "CNXCC ROUTE: $var(client1) has $var(count1) call(s)");
if ($var(count1) == $var(max_chan1)) { xlog("Too many channels for customer"); sl_send_reply(403, "Forbidden"); exit; }#!endif
Now the problem that I am facing is that with multiple UACs (all with same ruri - 10.97.116.36) dialing some pstn numbers, the value of "count1" remains 1 for all cases. Hence, my purpose is defeated because the restriction is not being laid and more than 'max_chan' no. of callers are able to make the call.
Could you please help me achieve this goal.
Thanks !

HI Carlos,
Thanks for reply.
In my case the key is SIP Server IP. My kamailio Proxy is connected to many sip server IPs say 5. I want to limit maximum channels per sip server ip. So I set max channels per sip server ip as cnxcc_set_max_channels("$var(client1)", "$var(max_chan)"); and my $var(client1) = "10.97.116.36"; is one of 5 sip servers connected to Kamalio.
Now I use your cnxcc_get_channel_count("$rd", "$var(count1)")) value(count1) to compare to the max_limit of the channels allowed for this sip server. Psuedo Variable $rd is coming correctly that is same as sips erver IP[$var(client1)]. But the problem is that cnxcc_get_channel_count("$rd", "$var(count1)")) is always setting the value 1 in $var(count1) variable even though there are more calls runnning than what was set to be max_chan (which was 100 in my case).
Any pointers to achieve this matter ?

Hi Rahul,
I don't understand your example. In that case, you are always using "10.97.116.36" as key, meaning that all calls will be hanging from same root.
If you want to use the request-uri domain part, use $rd, not the full $ru. This will of course lead to 1 call being reported always, since request-URIs tend to be different from each other.

Hi Rahul,
*if($var(client1)!="null") *should be *if($var(client1)!="$null"). *You are doing a string comparison with the string value "*null*".
Also make sure the dialog matching is correct: append these event routes to your config file:
*event_route[dialog:start] {* * xlog("Dialog started");* *}*
*event_route[dialog:end] {* * xlog("Dialog ended");* *}*
*event_route[dialog:failed] {* * xlog("Dialog failed");* *}*
You should see a "dialog started" and "dialog ended" for every successful call.
Please do those modifications and see what happens.
Regards, Carlos

Hi Rahul,

even in the last IF, the double-quotes have to be removed around "$null" -- just compare with $null, because doublequotes there enforces a static string.
Cheers, Daniel
/. /You are doing a string comparison with the string value "/null/".
Also make sure the dialog matching is correct: append these event routes to your config file:
/event_route[dialog:start] {/ /Â Â Â Â xlog("Dialog started");/ /}/ / / /event_route[dialog:end] {/ /Â Â Â Â xlog("Dialog ended");/ /}/ / / /event_route[dialog:failed] {/ /Â Â Â Â xlog("Dialog failed");/ /}/
You should see a "dialog started" and "dialog ended" for every successful call.
Please do those modifications and see what happens.

My kamailio Proxy is connected to many sip server IPs say 5. I want to limit maximum channels per sip server ip. So I set max channels per sip server ip as cnxcc_set_max_channels("$var(client1)", "$var(max_chan)"); and my $var(client1) = "10.97.116.36"; is one of 5 sip servers connected to Kamalio.  Now I use your cnxcc_get_channel_count("$rd", "$var(count1)")) value(count1) to compare to the max_limit of the channels allowed for this sip server. Psuedo Variable $rd is coming correctly that is same as sips erver IP[$var(client1)]. But the problem is that cnxcc_get_channel_count("$rd", "$var(count1)")) is always setting the value 1 in $var(count1) variable even though there are more calls runnning than what was set to be max_chan (which was 100 in my case).  Any pointers to achieve this matter ?     On Tue, Jun 3, 2014 at 2:18 PM, Carlos Ruiz DÃaz <carlos.ruizdiaz@gmail.com <mailto:carlos.ruizdiaz@gmail.com>> wrote: Hi Rahul, I don't understand your example.

*. *You are doing a string comparison with the string value "*null*".
Also make sure the dialog matching is correct: append these event routes to your config file:
*event_route[dialog:start] {*
xlog("Dialog started");**}*
*event_route[dialog:end] {*
xlog("Dialog ended");**}*
*event_route[dialog:failed] {*
xlog("Dialog failed");**}*
You should see a "dialog started" and "dialog ended" for every successful call.
Please do those modifications and see what happens.

Presumably in recent versions (since the comparison fix), $var(…) cannot be compared with $null. Should this be comparing with an empty string instead or using a pv type that can be null?
