1. During blind transfers and supervised/assisted transfers, the media gateway attempts to use the
same channel/port for performing transfers (if these types of transfers are supported by the PBX).
This minimizes the number of ports required for transfer applications like automated attendants.
2. Some PBX integrations require that the same ports be used to turn on and off MWIs. The Dialogic
media gateways remember which port turned on an MWI for an extension. However, this
information is lost if the media gateway is reset.
PBX Compatibility
Dialogic media gateways support a number of protocols, providing compatibility with a wide variety of
PBX systems, for example: analog dual-tone multi-frequency (DTMF), serial (RS-232),
channel-associated signaling (CAS), and Q signaling (QSIG).
Dialogic media gateways are compatible with more than 20 PBX systems from several manufacturers.
Specific configuration of these PBX systems is provided by Dialogic. Refer to the
Dialogic DMG1000 and
DMG2000 Media Gateway Integration Notes available from the Dialogic website
(http://www.dialogic.com/support/) for compatibility and PBX configuration guides.
The PBX integration configuration settings vary depending on the PBX manufacturer, PBX model and
version, and integration type. For specific instructions, refer to the appropriate Dialogic configuration
guide for the PBX model and integration type.
Dialogic has PBX-specific configuration files that can be imported into the media gateway to ensure that
the PBX-specific settings are configured correctly. The media gateway software available from the
Dialogic Service Center (http://www.dialogic.com/support/) contains the latest version of configuration
files for the PBXs that they support.
