Integrated Transfer Codes

Some PBX systems use inband DTMF signalling (as opposed to tone-and-cadence or out-of-band signalling) to signal the current status of an outbound call.  The DV2000/DV4 refers to this style of signalling as integrated transfers since call transferring is the most common (but not only) situation in which these codes are used.

The settings that define each possible call status signal are stored  in a configuration file named integration.ini which is located in the VMSYSTEM folder.  Assuming a default installation, it would be located in:

C:\DUVOICE\VMSYSTEM\integration.ini

Your installation may vary.

This figure below shows the default values for all supported settings.  They are used in conjunction with the integrated transfer type that can be assigned on the Transfers tab in the Class of Service template.  There are several settings that specify the inband DTMF codes the PBX sends to the VMS for call progress during an integrated transfer.

These codes vary from switch to switch, and a given PBX may not support all of the codes listed.  Only some PBX switches support this type of transfer. If your PBX does not support integrated transfers, these settings are irrelevant and you should not use the integrated transfer type in any COS template.
