* commit '69d643b5':
  Properly handle NULL var_name for switch_play_and_get_digits

Do not set "_invalid" in case var_name is empty or unset. While at it,
clear the "foo_invalid" variable before doing anything else when a regex
is passed, this ensures that the variable really reflects the current
run.

Fixes an issue in original FS-7783 feature.

* commit '8b42c77c':
  FS-9079: [mod_callcenter] Add ring-progressively strategy

A new strategy is now available through mod_callcenter, which aim
is to provide a mix between top-down and ring-all strategies.

If set to ring-progressively, the strategy will call an agent, and
then a second agent, and then a third agent, without cancelling
previous calls.

The delay between each call is 10 sec by default, but it can be
changed using the queue variable ring-progressively-delay.
