Dialogic® PBX Integration Board User’s Guide
<ESC>KR acts as a key press (which is Display Key 02, the far-right display
key).
Aborting the Transfer
A transferred call can be aborted at any time (prior to completing the transfer)
by pressing the appropriate appearance key where the original call resides.
The application can perform this only in a supervised transfer mode. For
example, if the original call resides on the first appearance key (Memory
Button 01), dialing dx_dial(<ESC>K1) brings the original caller back to an
active state. Another way to abort the transfer is with dx_dial(<ESC>KP),
where <ESC>KP acts as a key press (which is Display Key 00, the far-left
display key).
4.5.9. Called ID on Forwarded Calls
NOTE: The extbuilder (extension builder) tool described in this section is
supported on the Nortel BCM only.
If a phone forwards a call to a D82/D42 port, the d42_gtcallid( ) and
d42_gtcallidex( ) functions rely on a configuration file to map the given
phone’s name to an extension, when it is determining the CPID. This feature is
not required if the phone labels are left as their default labels, which are the
extensions.
The configuration file, named bcm_phone_dir.cfg, contains several fields:
• enabled toggle (default is disabled)
• maximum directory size (default of 284 entries, which corresponds to the
maximum number of digital phones supported on the BCM 400)
• time-stamp check time (default is 5 minutes)
• directory of phone name to extension
This file allows the d42_gtcallid( ) and d42_gtcallidex( ) functions to map
phone names to the phone’s extension.
The time-stamp check field specifies the number of seconds before checking
the configuration file for any changes. If the configuration file has been
updated since the last read, the configuration file is re-read into the library.
