[SR-Users] Re: Possibility to print values of Core Keywords in Kamailio configuration file
Hello Henning,
Thank you for your reply.
I am using sipsak for testing purposes and learn more about Kamailio, I was
using SIPp fine before. My goal is to identify the source port from the User
Agent Client (UAC). Here is the command I use in sipsak to send an OPTIONS ping
request:
```sipsak -s sip:proxy_server@33.33.33.4:5060 -l 5060```
the -l flag to identify the source port.
In my Kamailio configuration file, I perform a basic check like this:
```
if ($sp != 5040 && $sp != 5060) {
sl_send_reply(403, "Forbidden");
xlog("this $rm received, is forbidden\n");
exit;
}
```
When my Kamailio server receives the OPTIONS request from sipsak, it sends a
403 error response.
Using sngrep, I observed the following:
```
SIP From= sipsak@33.33.33.99:5060
SIP To= proxy_server@33.33.33.4:5060
Source: 33.33.33.99:36593
Destination: 33.33.33.4:5060
```
However, the source port appears to be random (36593 in this case) rather than
the expected 5060. This leads me to believe that Kamailio checks the source
port from the transport layer (I am not certain about this). The $sp value in
this case is 36593, not 5060.
I tried several ways to force sipsak to send the packet from port 5060, but I
couldn't achieve this. While sipsak correctly sets the number port 5060 in the
From and Via headers, it seems to use a random source port at the transport
layer.
Cheers,
Mohamed.

Hello, are you saying you are getting a different result when using: - src_port, vs. - $sp If not, please give more details what you are interested in.

Yes, the pv module has many useful pseudovariables, and many of the core keywords can be accessed through pv. However, I am facing an issue with the source port of the SIP message. When I use $sp, it shows the source port of the transport layer, not the SIP application layer. I want to explore other keywords to find the exact SIP application layer source port.

Hello Victor, I am impressed by how useful and helpful this module is. Thank you very much, I have tried it. It is very important to check the status of variables before and after a given route, as well as the SIP_IN and SIP_OUT messages. I have configured the mask parameter with a value of 32. However, I still haven't received the core keyword values. Thank you again, I really needed to know about this module.

I think all of them exist as pseudovariables and can be found in the pv cookbook. /O __ Kamailio - Users Mailing List - Non Commercial Discussions To unsubscribe send an email to sr-users-le...@lists.kamailio.org Important: keep the mailing list in the recipients, do not reply only to the sender!
