EZ VMS Lite
Normally, a call is transferred by hook flashing to put the caller on hold and then dialing
the extension number to which the call is to be transferred; and to retrieve this call,
hook-flash again. However, for some PBX systems, instead of hook-flashing to transfer or
retrieve a call, a string is to be dialed which may or may not include a hook flash.
Examples:
Transfer string = *1<Hook-flash><Pause><Extn>. Enter "*1HPE"
Retrieve string for Busy = <Hook-flash>*2. Enter "H*2"
4.4.1.5 Usage and PMS Parameters
Extension Length : Extension Length determines the number of digits present in an
extension or in a mailbox. Except operator extensions, all types of extensions and
mailboxes depend on Extension Length.
To change the Extension Length, all entries under the extension list, mailbox list, fax
extensions, distribution list and single digit plans must be deleted.
The allowed extension lengths are 2, 3 or 4. Default is 3.
Time before Deciding No-Answer : When a call is transferred to an extension and there
is no answer from that extension, the EZ VMS Lite waits for a certain time before
deciding that there is no answer from that extension. This no answer time is
programmable from 9 seconds to 27 seconds.
Valid value ranges from 3 to 9 where the value is in multiples of 3 Seconds. Default value
is 3 (9 seconds).
Hang-up Tone Detection Time : You have to enter this value in two-digit format. The
value for this field may vary from 10 to 49 (both inclusive). Default value is 10. The value
for this field gets multiplied by 33 milliseconds.
Conflict Timer Value : Conflict Timer Value is the time for which the EZ VMS Lite waits
for the caller to dial the second digit after the caller has dialed the first digit.
If the second digit is not dialed before the conflict timer delay elapses, the first digit is
treated as a Single digit dial entry and the call is transferred as per the Single digit dial
plan. If that digit does not have any corresponding single digit plan entries, the call is
transferred to the Operator. If the second digit is dialed, the unit waits for further entries
if necessary and transfers the call accordingly.
This value ranges from 2 to 5 and is in seconds. Default value is 3.
Transfer Type : The EZ VMS Lite supports three different modes of call transfers – Blind,
Semi supervised and fully supervised. In the Blind mode, the unit transfers the call and
hangs up. If the called extension is busy or if there is no answer, the PBX calls the EZ
VMS Lite back and sends an in-band string to inform that this is a call-back on busy / no
answer.
