Description
Set up CM to enable Auto Hold, so that the phone
automatically places an active call on hold when the
user answers or resumes a call on another call
appearance. Use the System Parameters Features
form, page 6.
Administer a coverage path for both phone
demonstration and normal operations. Use the
Coverage Path form and give it a number, for
example, Coverage path 1. If Voice Mail is
available, administer the hunt group or VDN,
depending on the type of VM system being used.
Enable enhanced conference display to support the
user experience for conferences. Set Block
Enhanced Conference Display on the Class of
Restriction (COR) form to No. Use the command
Change COR, followed by a number, to view the
form and make the change. This is a sample of the

licenses. This feature requires trunking to work
properly. Use the following command to make the
change: change off-pbx-telephone
station-mapping <station>

codec-set <number> command on CM. Ensure

that wide band audio works only for direct-IP calls
between two 96xx endpoints, either with both
registered to the same server, or registered to
different servers when connected by IP trunks. Calls
between two 96xx phones connected by an IP trunk
do not currently support wide band audio when the
call is shuffled so that the media travels directly
between the two phones. Calls that involve three or
more parties, even if all parties use IP phones, do
not use wide band. Calls between two phones
where audio is terminated at a port network/
gateway (PN/GW) media resource will not use
wideband.
Ensure that G.722 is added to all codec-sets that
can possibly be used between all regions on the IP-
Network Regions form . Technically, G722 does not
need to be first. What is needed, however, is that all
the non media processor-supported codecs (G722,
