Configuring One Number Access
226 AltiWare OE System Installation & Administration Manual
Note:
When this option is enabled, a single workgroup can have no
more than 20 members set to Ring All. If members are using IP
extensions, the system will require an equal or greater number
of available IP ports than the number of IP extensions. For
example, with 15 IP extensions set to Ring All in a single
workgroup, the system needs to have at least 15 IP ports
available at any given time.
In addition, calls to workgroups that have this option enabled
have higher priority than other workgroup calls. Therefore, if
an agent belongs to multiple workgroups, one of which has this
option enabled, a call to that workgroup will be picked up
before others, regardless of its Wait Time in the queue.
Setting a Service Level Threshold
For workgroup numbers only, you can use the Service Level Threshold
scroll box to select the length of time in seconds that a call can be in queue
before the call is logged in workgroup performance statistics as having
exceeded the allowable service level limits. You can set the value to any
number between 1–1200 seconds.
Configuring One Number Access
One Number Access (ONA) allows you to identify specified callers to be
connected to the user without having to dial more than one number. The
system searches for the caller and, if a match is found, searches for the user
through specified forwarding numbers and connects the call if possible. If
the system is unable to connect the call, it is sent to the extension user’s
voice mail.
Note: Options in the window are disabled unless One Number Access
has been enabled as a No Answer option in the Answering window
as discussed in “Enabling One Number Access” on page 225.
Furthermore, if the Enable Do Not Disturb option is selected in
the Answering window, the call is forwarded to voice mail
regardless of ONA settings.
