NOTE:
When you move ESM circuit packs, you MUST remove the DS1 and
signaling group translations. You cannot use the change circuit pack
command.
When a vector is used to route video (56K/64K) calls to a hunt group comprised
of data extensions, the vector
must
have the multimedia field set to n. This field
causes multimedia calls routed through th e vector to receive early answer
treatment prior to processing the vector steps. This provides a talk path to the
caller for announcements or immediate conversation with an agent and starts
network billing for the incoming call when vector processing begins.
Understanding the multimedia complex
1-number access. 1-number access permits originating users to make voice or
multimedia calls to a Basic multimedia com plex by dialing the same number for
either type of call. The number may be the voice station extension or the data
module extension. If the incoming call is a voice cal l, DEFINITY ECS directs it to
the telephone. If the incoming call is 56K or 64K data call, DEFINITY ECS
recognizes it as such and sends it to the multimedia endpoint. Likewise, if a voice
call is addressed to the data extension, the system recognizes this and directs the
call to the voice station.
Calls originating on the same switch as th e Basic mode complex destination may
always use 1-number access for voice or video. In order to take advantage of
1-number access for calls originating from a remote location, the incoming calls
must arrive over ISDN-PRI trunks. If the system is setup with separate data
non-PRI digital facilities multimedia calls must be made to the data extension.
AVD (Alternate voice/data) trunk groups cannot be used to provide 1-number
access with MMCH. If the AVD trunk group has a BCC of 0, all calls arriving
over the AVD trunk to the Basic mode c omp lex will be assumed to be voice calls.
If the AVD trunk group has a BCC of 1 or 4, all calls arri v ing over the AVD trunk
to the Basic mode complex will be assumed to be multimedia calls.
Originating voice calls. All voice calls are originated at the voice station.
Originating multimedia calls. For a Basic mode complex, multimedia calls are
normally originated at the user’s multimed ia equip ped PC. T hese multi media calls
use the associated station’s COR/COS.
