Early Answer. The answering party may administer their station to avoid hearing
hourglass tone. With the station screen
Early Answer field set to y, the system
answers the incoming multimedia call on behalf of the station and establishes the
H.320 protocol. After audio path has been established, the call will then alert at
the voice station of the Basic complex destination. The station may then answer
by going off-hook and will have immediate audio path. No hourglass tone will be
heard by the answering party.
If the H.320 field is not set to
y for the telephone of a Basic multimedia complex,
H.320 calls alert at the multimedia endpoint until the caller drops. If an H.320 call
is directed to a telephone with H.320 set to
n, the system denies the call.
You can assign H.320 conversion to any voice station.
Authorization. Multimedia complexes require the same types of authorization
(COR/COS) as standard telephones. If a call is addressed to the voice extension,
the system checks the COR/COS of the telephone, whether the call is voice-only
or multimedia. If a call is addressed to the data extension, the system checks the
COR/COS of the data endpoint. If the call is subsequently redirected to the voice
station, the system does a second COR/COS check for the authorization of the
voice station. Calls originated from the PC use the COR/COS of the voice station.
Adjunct Switch Applications Interface . ASAI is not expected to support
call-association for data calls. Therefore Avaya does not recommend that you use
ASAI for multimedia.
Administered Connections. Basic Multimedia endpoints may serve as the
origination point or destination of an administered connection.
Authorization and Barrier Codes. Basic Mode multimedia users or off-premises
PC users may not be able to respond to prompts for authorization or barrier codes.
Multimedia endpoints do not recognize the prompts.
An on-premises user might be able to use Remote Access and enter the entire digit
string at once before launching the call, but it would be better to eliminate the
need for such codes for multimedia users who need to call off premises.
Bridged Appearances. Voice users can bridge onto a call if the user has a
bridged appearance of a voice member of the call.
Call redirection. Calls directed to either member of the Basic multimedia
complex are subject to redirection (coverage, forwarding). Avaya MultiVantage
converts calls to voice before sending them to coverage. Calls redirected through
call forwarding maintain multimedia status if forwarded from the data endpoint.
