   3. Parameters

        3.1. timer (str)
        3.2. exec (str)

1. Overview

   The module executes route blocks on a timer base. It can create new
   timer processes and execute many route blocks on same timer.

   A static faked SIP message is given as parameter to called functions,
   so all functions available for REQUEST_ROUTE can be used.

2. Dependencies

   2.1. Kamailio Modules
   2.2. External Libraries or Applications

2.1. Kamailio Modules

   The following modules must be loaded before this module:
     * No dependencies on other Kamailio modules.

2.2. External Libraries or Applications

   The following libraries or applications must be installed before
   running Kamailio with this module loaded:
     * None.

3. Parameters

   3.1. timer (str)
   3.2. exec (str)

3.1. timer (str)

   The definition of a timer. The value of the parameter must have the
   following format:
     * "name=_string_;mode=_number_;interval=_number_"

   The parameter can be set multiple times to get more timers in same
   configuration file.
     * name - name of the timer.
     * mode - if set to 1, will create a new timer process.
     * interval - timer interval in seconds or micro-seconds (the value
       must be ended in 'u'). For micro-seconds intervals, mode is set
       always to 1.

   Default value is NULL.

   Example 1.1. Set timer parameter
...
# time interval set to 10 seconds
modparam("rtimer", "timer", "name=ta;interval=10;mode=1;")
# time interval set to 100 mili-seconds
modparam("rtimer", "timer", "name=ta;interval=100000u;mode=1;")
...

3.2. exec (str)

   Specify route to be executed on timer. The value of the parameter must
   have the following format:
     * "timer=_string_;route=_number_"

   The parameter can be set multiple times to get more routes executed on
   same timer.
     * timer - name of the timer.
     * route - the index of the route to be executed.

   Default value is NULL.

   Example 1.2. Set exec parameter
...
modparam("rtimer", "timer", "name=ta;interval=10;mode=1;")
modparam("rtimer", "exec", "timer=ta;route=8")

route[8] {
    xlog("timer routine: time is $TF\n");
    # delete from my sql cache table entries older than 2H
    sql_query("delete from kamailio_cache where last_updated<$TS-3600");
}
...
