Hook Flash the Central Office Line (Centrex and CLASSSM features)
Hook Flash the Central Office Line 
Flash

You can send a hook flash to the central office line, rather than have the hook flash interpreted by the Nex- Path Telephony Server. This is only useful if you have Centrex lines or CLASSSM features, such as three way calling, enabled on your outside lines.
Note The ability to hook flash a Central Office line can be enabled or disabled on a CO line by CO line basis in the NexPath Telephony Server. This feature must be enabled with the administration software in order for the sequence to work. Otherwise the sequence is ignored.
To send a hook flash to the central office line (see the note above):
1.While connected to an outside (central office) line, enter Flash
9
. You should receive the signal from the central office that the sequence is recognized, usually three short beeps and then central office dial tone.
For example, to setup a three way call using CLASSSM features:
1.While connected to an outside (central office) line and talking to the first party, enter Flash
9
. You should receive the signal from the central office that the sequence is recognized: three short beeps and then central office dial tone.
2.Dial the second party.
3.When you are connected, enter Flash
9
again. You should now have a three way call.
Note You must subscribe to CLASSSM features from your telephone company in order to use the three way calling described above.
