[SR-Users] Rate limiting

[NITESH BANSAL]

Finally I got it working. The issue was that I was trying to use pikelimit with Kamailio version 4.1, 4.1 version doesn't allow for dynamic pipe creation.

In the end, I backported pipelimit code from Kamailio version 4.2 and used pl_check function to create dynamic pipes.

What I really want is something similar to the Pike module, which dynamically controls the traffic based on the source address.

In my case, instead of the source address, I need to control traffic based on the LOGIN, there is no way to statically configure

the LOGIN, I want the module to treat the LOGINs just like dynamic source addresses.

Hello,


I tried calling the function pl_check , this is how I'm trying to use.


$var(check_result) = pl_check("$avp(s:LOGIN)");


This is always returning -2, shouldn't it create a new PIPE next time it receives a message from the same login?

I'm using Kamailio 4.1, could that be the difference?


Thanks,

Nitesh

I have never used pipelimit with a database.

The essence is the ability to pass a dynamic pipe to pl_check() which is created if it doesn't exist.
