EZ VMS Lite
Answer Detection Time: This is the minimum duration of voice frame that must be
detected by the EZ VMS Lite to consider a call as having been answered.
Enter the new value in two-digit format that are in multiples of 33 milliseconds. The
value ranges from 01 to 99. Default value is 07. Too small a value may result in false
detection of a call as answered whereas too large a value may result in the caller missing
the first word spoken by the called party.
4.4.1.4 Strings
These are strings sent by PBX to inform EZ VMS Lite about the status of the call. There
are various types of in-band strings as may be seen in the screen view. The text box for
entering In-band signaling strings accept digits, *, # and a few alphabets like p, P, h, H, e,
E, i, I, A, B, C, D where, “p, p = Pause”, “H, h = Hook-flash”, “E, e = Extension”, “I, i =
Ignore character” and A, B, C, D which are the DTMF digits for these alphabets.
Wait Time For 1st Digit: This is the maximum time up to which the EZ VMS Lite waits
after going off hook to receive the in-band strings. Enter new value in two-digit format.
The wait time value ranges from 00 to 99 where the actual wait time is equal to the
entered value multiplied by 50 milliseconds.
Default value = 30
If this value set by the installer is too small, the EZ VMS Lite may miss the first few digits
of the string or treat the digits as extension transfer digits. If this value is set too high,
outside callers may find a slightly longer silence between the time the unit answers the
call and the main greeting starts playing.
Wait Time Between Digits: This is the maximum time the unit waits in between digits for
the PBX to send the next digit. Enter the new value in two-digit format in the range 00 to
99. The actual wait time equals the entered value multiplied by 10 milliseconds.
Default value = 20
If the next digit is not received by the time this wait time elapses, the unit transfers the
call to the Operator.
Mailbox Login String: This is the string to be dialed by a user to gain access to his/her
mailbox. This string may also be programmed as a Speed Dial Key on the user’s phone to
allow single key access to his/her mailbox. Allowed alphabets are ‘E’, ‘e’, and P ’, ‘p’.
Example: *#E
Busy / No answer strings : Allowed alphabets are ‘e’, ‘p’, ‘i’, ‘a’, ‘b’, ‘c’, ‘d’ and their
capitals.
The Busy / No answer strings is a stream of characters sent by the PBX to the
EZ VMS
Lite to signal the status of a call which was transferred by the EZ VMS Lite earlier.
This method of signaling is required when the normal call transfer is done in the Blind
mode, where the
EZ VMS Lite dials the extension and hangs up. In such cases the PBX
