First Hook Flash [&] IM1200 provides two Hook Flash times for PBX programming.
First Hook Flash is usually used for transferring calls. “ &” is the symbol used to
represent First Hook Flash time.
Second Hook Flash [h] Most PBXes only uses one Hook Flash time for all
operations, while some PBXes require an alternative Hook Flash time to retrieve a call
on hold. Second Hook Flash is usually longer than First Hook Flash. “
h” is the
symbol used to represent Second Hook Flash time.
Extension’s Size This is the length (number of digits) of your PBX’s extension.
Disconnect Signal
In cases when the PBX wishes to notify IM1200 that the call
should be disconnected, the PBX will send a Disconnect Signal to IM1200. One such
case is when the caller hangs up the phone during the call transfer. IM1200 will
disconnect the call upon receiving this signal. The first digit of the Disconnect Signal
should be one of DTMF tones A, B, C, or D.

Setting Up IM1200 in Non-Supervised Mode
Some PBXes have the capability of sending call status information when the call is being
transferred. IM1200 can make use of this information and determine what action should
follow. In Non-Supervised mode, calls are released immediately after the transfer is
initiated and the PBX has to enable the Busy/No-Answer Forward to the voice mail port.
