Enhanced Mode Mm Complex - Avaya Communication Manager Administrator's Manual

Enhanced Mode MM Complex

Terminating Extension Groups
Basic mode data calls to a TEG are converted to voice and can terminate only at a voice
endpoint. Effectively, Communication Manager treats the multimedia-complex extension as a
voice-only endpoint.
Telephone Display
Display information for calls to or from a Basic multimedia complex contains the 1-number.
Enhanced Mode MM Complex
The Enhanced multimedia complex provides a much greater unified and integrated interface for
control of voice and multimedia calls. The multifunction voice station is used to control all calls,
whether voice or multimedia. The H.320 desktop video system is used to present the video
stream, data stream and (optionally) audio stream to the user. The H.320 desktop video system
is not used for call control. The Enhanced multimedia complex allows the multifunction voice
station to handle voice or multimedia calls in an almost identical manner. Each call appearance
on the voice station may represent a voice or multimedia call, allowing multiple voice or
multimedia calls to be present simultaneously on the station. The user may manage the
separate call appearances without regard to the voice or multimedia nature of the specific call.
The standard HOLD/TRANSFER/CONFERENCE/DROP actions may be applied to any call,
without regard to the voice or multimedia nature of the call.
1-number access
1-number access permits originating users to make voice or multimedia calls to an Enhanced
multimedia complex 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 call, Avaya
Communication Manager alerts the station of an incoming voice call. If the incoming call is 56K
or 64K data call, Communication Manager recognizes it as a multimedia call, inserts resources
to terminate the H.320 protocol, and alerts the voice station with a multimedia call.
Calls originating on the same media server as the Enhanced 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 non-PRI digital facilities for data, multimedia calls
must be made to the data extension of the Enhanced mode complex.
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 complex will be assumed to be voice calls. If the AVD trunk group has a BCC of 1 or 4, all
calls arriving over the AVD trunk to the Basic mode complex will be assumed to be multimedia
calls.
