Understanding the Multimedia Complex
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 Communication Manager converts calls to voice before sending
them to coverage. Calls redirected through call forwarding maintain multimedia status if
forwarded from the data endpoint.
Conferencing
A multimedia conference can consist of multimedia and voice-only conferees. All multimedia
conferees are added to a multimedia conference by a voice-terminal user on Communication
Manager , who acts as the controller of the multimedia conference. When the controller is a
Basic complex voice station, the controller must remain on the conference until all parties have
joined. Once all endpoints are on the conference, the voice-terminal user may put the call on
hold or drop, if the user wishes.
