any example which shows how can I create the dialog profile **value

need to control many SIP Server IPs with limited channels to each with
my** Kamailio Proxy.*

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 $var(count)
call(s)");
if ($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 ?

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

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

Hi Carlos,

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.

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 ?

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.
Regards,
Carlos

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.

Hi Carlos,
Please find attached the configuration file which I am using.
Kindly refer route[CNXCC] where I have tried to put the channel limitation
per SIP Server.

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,
sorry, I couldn't find time to do it. I will take a look tomorrow, or most
possibly during the weekend.

Hi Carlos,
Please find attached the configuration file which I am using.
Kindly refer route[CNXCC] where I have tried to put the channel
limitation per SIP Server.
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,
*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,
sorry, I couldn't find time to do it. I will take a look tomorrow, or
most possibly during the weekend.

Hi Carlos,
Please find attached the configuration file which I am using.
Kindly refer route[CNXCC] where I have tried to put the channel
limitation per SIP Server.
Thanks !

/. /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.

CarlosÂ

HI Carlos,
Â
Thanks for reply.
Â
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 $var(client1) =
"10.97.116.36"; is one of 5 sip servers
connected to Kamalio.
Â
Now I use your cnxcc_get_channel_count("$rd",
"$var(count1)")) value(count1)Â 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)"))Â 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).
Â
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.
Â
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.
Â
Below is the sample logic from
kamailio.cfg
***********************************************************************************************************************
 #Below lines to show an example of

Â
        Â

  $var(max_chan)  = 100;
 #!ifdef CNXCC_CHANNEL
         xlog("L_INFO",

Â
         $var(max_chan1) = 0;
         $var(retcode)  =

-1) {
                Â
xlog("Error setting up credit control");
                 return;
         }
Â
         $var(count1)   Â

Â
         if
(!cnxcc_get_channel_count("$rd",

                Â
xlog("Error getting customer's channel
count");
         }
         xlog("RAHUL : CNXCC

Â
         if ($var(count1) ==

                Â
sl_send_reply(403, "Forbidden");
Â
                  exit;
         }
 #!endif
******************************************************************************************************************************************************
Â
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.
Â
Could you please help me achieve this
goal.
Â
Thanks !

max_chan is equal to zero? You

Also, you are using for one call
the ID "x.y.z.a", and for the

same for calls that suppose to be
organized in the same group.
Please take a look at the docs.

I don't exactly know

that instead of using

use the domain part of

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?

. 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
