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 !

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.

Further, from the logs it seems that cnxcc_set_max_channels is returning -1 and I have no idea why it is failing.

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 $var(count) call(s)");
if ($var(count1) == $var(max_chan1)) { xlog("Too many channels for customer"); sl_send_reply(403, "Forbidden"); #if (!cnxcc_terminate_all("$var(client)")) { # xlog("Error terminating customer's calls"); #} exit; }#!endif
Could you please guide me where am I doing wrong ?

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.
Regards, Carlos

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 ?

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