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.
3.4.2.4
When a call is transferred to an extension and there is no answer from that extension,
the Synectix 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).
3.4.2.5
The Synectix 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 Synectix
VMS Lite back and sends an in-band string to inform that this is a call-back on busy / no
answer.
In the Semi supervised mode of transfer, the unit monitors the call after transferring
and if the called extension is busy or an invalid extension, it retrieves the call and
informs the caller accordingly. However, if it gets a ring-back signal from the called
extension, the unit hangs up and thus connects the caller to the called extension.
In the fully supervised mode, the unit monitors the call till the called party answers the
call or if there is no answer, it retrieves the call and informs the caller accordingly.
Default : Fully supervised mode of call transfer.

different units in the field for maintenance etc.
