Synopsis

Get an extension's state.
Introduced in Asterisk 1.6 as EXTENSION_STATE(), with a backport available for 1.4 as EXTSTATE().

Description

 The EXTENSION_STATE function can be used to retrieve the state from any
hinted extension.

For example:

  NoOp(1234@default has state ${EXTENSION_STATE(1234)})
  NoOp(4567@home has state ${EXTENSION_STATE(4567@home)})

 The possible values returned by this function are:
UNKNOWN | NOT_INUSE | INUSE | BUSY | INVALID | UNAVAILABLE | RINGING
RINGINUSE | HOLDINUSE | ONHOLD

 INVALID does not seem to be used on 1.6
