Repeat for each center you want to identify.
TIPS:
• A telephone does not show that external voice messages are waiting unless you enable VMSG
set for the lines assigned to each telephone under Line Assignment . Refer to table entry:
Vmsg set on page 411.
• Analog telephones connected to an GASM on systems running BCM 3.6 or newer software
can receive message waiting indicators if the analog line supports CLID. MWI indicator
settings for analog telephones or for analog telephones attached to ATA2s, are set under the
ATA heading. Refer to
“Determining analog settings” on page 424 .
• You can program up to five voice message center numbers, but many systems require only
one.
Setting outgoing name and number blocking
When you activate Outgoing name and number blocking (ONN), a user presses FEATURE 819 to
block the outgoing name and number on a per-call basis. The system flags the call to the Central
Office (CO) so that the name and number is not sent to the person you call.
ETSI note: ETSI lines may use the Calling Line Information Restriction (CLIR) supplementary
service to provide this feature.
ETSI PRI lines do not use a VSC. The line always uses Suppression bit to invoke the CLIR
supplementary service.
Business Communications Manager alerts the CO by two methods. The method used depends on
the type of trunk involved in placing the outgoing call.
• Analog trunks use a dialing digit sequence called a Vertical Service Code (VSC). The VSC
differs from region to region and must be programmed. Analog trunks with both tone and
pulse dialing trunks can have separate VSCs. Refer to
“Configuring ONN blocking service
codes” on page 487 .
• PRI trunks have only one VSC. No specific system programming is required. See ETSI note,
above.
• BRI trunks can be set to either:
— provide ONN using a suppression bit, which provides a notice from the system to the
central office to withhold CLI.
— provide ONN using a VCS, which is dialed out in front of the dialed digits (optional on
ETSI trunks). Refer to “Configuring ONN blocking service codes” on page 487 .
BRI trunk ONN settings are located under the loops settings. Refer to “Identifying BRI
T-loops (T1 profiles)” on page 279 or “Identifying BRI T-loops (ETSI, QSIG)” on page 282 .
Message wait
cancellation string <string> indicates that the voice messages have been retrieved.
This is a default NSI string for message waiting.
