Hi, Ximena!
In 1.7, the *queue* parameter was used to map a queue with a certain SIP
message. Basically this is no longer needed/supported, since you can do
this "mapping" directly from the script.
The *pipe* parameter was a static mapping between a "pipe", the
algorithm used for ratelimiting and the limit. These have been replaced
by the rl_check() function, which now instead of the index of the pipe,
receives all the parameters that would have given in the static mapping.
For example, the following config in 1.7:
modparam("ratelimit", "queue", "0:REGISTER")
modparam("ratelimit", "pipe", "0:TAILDROP:200")
route {
...
rl_check("0");
...
}
can be translated something like:
route {
...
if (is_method("REGISTER"))
rl_check("0", "200", "TAILDROP");
...
}
Note that you no longer have a static number of pipes, but rather they
can be created dynamically during runtime. Simply assinging a different
name (the first parameter of rl_check function), will result in creating
a new pipe (at runtime).
I hope my explanations facilitate your migration.

Hi all!
I'm triying to migrate an opensips configuration script from opensips
1.4.2 version to the opensips 1.9.1 version.
I have found an issue regarding to the new usage of the *rl_check
*function in the ratelimit module.
Until opensips 1.7.x version we could use that function easily as follows:
|rl_check([pvar])|
Until 1.7.x opensips version we could also configure:
|queue| (integer:string)
|pipe| (integer:string:integer)
But from opensips 1.8.x version I'm finding a new usage for that function:
|rl_check(name, limit[, algorithm])|
And I can't configure anymore the *queue *and *pipe *parameters.
My question is how can I use the new definition of the *rl_check
*function, since I don't understand where I can save the information
that I previously saved using the missing queue and pipe parameters, and
now the function needs more parameters to be used.
Many Thanks!
