Yeah, I do need a dynamic GUID.
From what I understood from Daniel:
use $sruid to get the unique id*(it will be a new value for each use
of it).*
yes, for clarification:
$var(x) = $sruid;
$var(y) = $sruid;
the result is that $var(x) != $var(y)
Does this mean that for each request the $sruid variable returns a new
unique id or the same for each kamailio instance?
For a better understanding, the value is made of several components:
- server_id global parameter, only if set in config and different than 0
(which is default value)
- timestamp when kamailio is started
- process id for each worker
- an incremented value for each sruid (or a random value each time, but
this is not exported in config)
The collision across many instances even if server_id is not set is very
unlikely. It would require that the instances are started at the same
time and the task scheduler gives the same PID values for kamailio
processes. But as said, if you have multiple instances, you can just set
different server_id values.
Adding the alternative to use values generated by libuuid should not be
that hard at all, for what I needed so far, $sruid was never colliding
(and again, is very unlikely to happen anyhow).
Cheers,
Daniel

Oh, I thought you were looking for a dynamic GUID, not a constant UID
for an instance.

Actually there is a variable giving an unique id
for kamailio - just
load kex module and use $sruid to get the unique
id (it will be a new
value for each use of it).
If you have multiple instances of kamailio, then
set server_id global
parameter to make the values unique across
instances.
Cheers,
Daniel
