[SR-Users] Consuming 300 Multiple Choices

[I.Pavlov]

Hi Geoff, to grab "rate"-attribute try to use
"$sel(contact.params["rate"]);"-expression. For example, in my test with
sipp, I used Contact: sip:sipp@[local_ip]:[local_port];q=0.1;rate=0.002 and 

 

$var(rate)=$sel(contact.params["rate"]);

xlog("CONTACT URI PARAMS: $var(rate)");

 

/usr/sbin/kamailio[25909]: ERROR: <script>: CONTACT URI PARAMS: 0.002

 

Next, you can try to log $var(rate) with acc like this:
acc_log_request("RATE: $var(rate)");

Subject: [SR-Users] Consuming 300 Multiple Choices

 

Greetings,

I am looking for a way to get some extra information out of the Contact
header when consuming a multiple choices response.  I am using uac_redirect
to populate the branches.  

get_redirects("*");
t_load_contacts();
t_next_contacts();
        
t_on_failure("2");
t_relay();



In my failure_route[2] I am just doing:

t_next_contacts();

t_on_failure("2");
t_relay();

In my Multiple Choices packet, I am getting some additional information that
I would like to log using the acc module.  There is a "rate" attribute that
defines how much the outbound leg is going to cost to terminate.  Here is
how the packet looks:

How would I grab that attribute and log it using acc?

Thanks,
