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.

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].

*Hello,*
*Please accept my apologies for asking a simple question - Is there any example which shows how can I create the dialog profile **value based on the SIP domain or SIP Server IP (IP like- 112.23.134.5). I** need to control many SIP Server IPs with limited channels to each with my** Kamailio Proxy.*
