Auto-page — Lets the user turn auto-page (defined below) on or off at his/her station.

Note: This feature is used in conjunction with the directory names recorded in Function 62 and is

not active until a directory name is recorded for the extension.

If the station user has his/her mailbox set to answer with personal greeting 3 and a caller presses 3
to page that user, this feature automatically pages the station user in the page zones entered in
Function 31. If no page zone is entered, all IVX Digital Feature Phones on the system are paged.

Default: Disabled.
Note: When auto-page is enabled, IVX 128 will use the last installed idle digital port to perform the

page. Therefore, if a phone is on the last installed port (e.g., X111 on a system with only a
612 Card), the phone’s user may experience a brief delay in telephone operation if he/she
picks up the handset (or presses SPEAKER) during the auto-page.

IVX 128 Plus: additional features

11. External forwarding — Allows the station user to enable the off-premises-“reach-me” feature (the

user can give, to callers who are forwarded to his/her voice mailbox, the option of trying to reach
him/her at another number). This requires a trunk-to-trunk transfer and will use two CO lines for the
length of the conversation. The user must set his/her mailbox to answer with personal greeting 2
and inform the caller to press 4 for this option. After the system dials the last digit of the external
forwarding number, it will begin to play a prompt saying, “You are receiving a forwarded call. Press
any key to accept.” This prompt will play continuously for 30 seconds. When DTMF is detected at the
remote end, both trunks are connected. If no DTMF is detected, the caller is forwarded to the user’s
voice mail.

Default: Disabled.

Note: While the two trunks are connected, the system constantly monitors the lines for open

loops. If it detects an open loop on either line, it terminates both CO connections.
Additionally, the system periodically will monitor for voice on the connected COs. If it detects
no voice traffic, it terminates both CO connections. Finally, if both COs are connected for a
programmable period (default is 60 minutes), the system will terminate the connection,
regardless of the presence or absence of activity.

12. Forwarding to toll numbers — This feature is used in conjunction with external forwarding (see

previous item). When enabled, this feature lets the user program a long-distance number for
external forwarding.

Default: Disabled.

13. Trunk-to-trunk transfer — When enabled, allows the station user to initiate a trunk-to-trunk transfer.

While connected to a CO line, a station users can press either TRANSFER or CONF followed by
his/her line access code(s), dial an off-site number and then complete the trunk-to-trunk
connection by simply hanging up or pressing CONF.

•

If the user is performing a trunk-to-trunk transfer and hangs up, both parties are connected via a
trunk-to-trunk connection.

•

If the user is performing a trunk-to-trunk conference and presses CONF the second time, all
parties are connected in a conference. The user can then hang up and any remaining parties in
the conference will stay connected via a trunk-to-trunk connection.

Default: Disabled.

Note: While the two trunks are connected, the system constantly monitors the lines for open

loops. If it detects an open loop on either line, it terminates both CO connections.
Additionally, the system periodically will monitor for voice on the connected COs. If it detects
no voice traffic, it terminates both CO connections. Finally, if both COs are connected for a
programmable period (default is 60 minutes), the system will terminate the connection,
regardless of the presence or absence of activity.

Important:

USE OF FEATURES, SUCH AS TRUNK-TO-TRUNK TRANSFER, THAT REQUIRE TRUNK-TO-TRUNK
CONNECTIONS WILL INCREASE THE RISK OF TOLL FRAUD. IN NO EVENT SHALL ESTECH SYSTEMS,
INC. BE LIABLE FOR ANY DIRECT, INDIRECT, INCIDENTAL OR CONSEQUENTIAL DAMAGES
WHATSOEVER INCLUDING, BUT NOT LIMITED TO, FRAUDULENT TOLL CHARGES, LOSS OF
BUSINESS PROFITS, BUSINESS INTERRUPTIONS, OR ANY OTHER COSTS OR DAMAGES RELATED
THERETO, ARISING FROM THE USE OF THESE FEATURES.
