DXP, DXP Plus and FX Issues
You can avoid many call-processing problems by being sure that the PCIU telephone has line appearances for the
lines on which it handles external calls.
You must set the Enhanced LCD display feature to No (its default setting) for the class of service in which the
PCIU resides. If the setting is Yes, caller ID information may be invalid and call processing may intermittently
fail.
Changing DND status from within a TAPI application works best when you map a DND button.
DSU/DSUII Issues
Changing DND status from within a TAPI application ONLY works when you map a DND button.
Problems and Limitations
General Issues
The SPI software no longer supports Visual Call Manager (VCM).
If users make a conference with two lines and then place the conference on hold, the conference may eventually
recall. If it does recall, the SPI software may not properly identify the states of the calls and the system may lose
call control.
If users attempt to dial a number that has the same area code as the area code entered in the My Location tab of
the Telephony Control Panel settings, the system may dial the number as a local number(just the seven-digit
number). TAPI applications typically provide an option to Dial as a long distance call or Dial as a toll call . If
not, these applications at least allow users to edit the digits to be dialed. The PCIU service provider has no
control over what digits an application requests to dial.
Issues Specific To ACT! 3.X, 4.0*
Except for application-initiated transfers and conferences, ACT! Does not provide call processing support for
more than one call at a time. Therefore, when multiple calls are necessary at the same time, users must manually
handle these calls from their telephones.
When users hang up a conference from ACT!, the Hang Up button remains the only active option even though
the call has actually hung up. To cause the proper options to be displayed, users must press the intercom and
speaker buttons on the telephone.
If users make a call, place it on hold, and then manually make another call, the first call may eventually recall at
which point ACT! presents the Answer option. If users click Answer, the system answers the call but then drops
the call in a few seconds. To prevent this, when multiple calls are necessary at the same time, users must
manually handle them from their telephones.
