PRB: DDI not supported with CAPI cards behind Meridian switches



ID: ZTN1517

This Zetafax technical note applies to:

  • Zetafax 9 and later
  • Meridian PBX


Zetafax server reports:

QUEUEMAN    - (W) - No match for received Direct dial - DTMF information '1234'

When a DDI number other than the one reported is rung.


Equisys support a range of active ISDN boards using our CAPI driver. The CAPI diver, when used in conjunction with a Meridian switch is unable to retrieve the Redirecting number (DDI number) presented by the switch. Instead we are presented the Called Party number for routing, which in this case is actually the pilot or phantom number.


Equisys have solutions from Brooktrout which do not use CAPI and support this phantom number presented by the switch.


This has been identified by Equisys as a problem with the software versions given above.
