====== Generic Call Filter Match ======
  * Use to limit the scope of the debug commands
  * Provides a centralized filtering system for voice and call processing debug and traces
  * E.g. display only certain called or calling number 

===== Configuration =====
  * Create Filter tag
  * Configure incoming call filter
  * Configure outgoing call filter
<code>
call filter match-list 16 voice
  incoming {called-number | calling-number | dialpeer | media | port | secondary-called-number | signaling}
  outgoing  {called-number | calling-number | dialpeer | media | port | secondary-called-number | signaling}
</code>

  * To debug
<code>
Router# debug condition {application | called | calling | card | glbp | interface | ip | mac-address | match-list | standby | username | vcid | vlan | voice-port} [options] {exact-match | partial-match}

! *** E.g.
Router# debug condition match-list 16 exact-match
</code>

  * Can also filter based on carrier-id or trunk group label
<code>
call filter match-list 16 voice
  source {carrier-id | trunk-group-label}
  target {carrier-id | trunk-group-label} 
! ** For example
  source carrier-id 228877
  target trunk-group-label 2546
</code>

===== Show =====
  * Identify the component that will use GCFM
<code>
Router# show call filter components
</code>

  * Review the configured match-list
<code>
Router# show call filter match-list [list <number>]
</code>

  * Verify the status of dynamic or match list-based GCFM conditions
<code>
Router# show debug condition [condition <identifier> | all]
</code>
