Managing MultiMedia Calling
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.
Intercept Treatment
H.320 calls that receive intercept treatment are treated like other data calls. H.320 calls cannot
be directed to an attendant for service because the attendant cannot have H.320 conversion
service.
ISDN Trunk Groups
Avaya highly recommends that you use ISDN trunks for multimedia calls. ISDN PRI trunks allow
complete 1-number access for an Enhanced multimedia complex. ANI provided over PRI trunks
allows correct routing of multiple bearer channels to the correct destination device. ISDN also
provides the bearer capability on a call by call basis which can be used to distinguish voice calls
from multimedia calls.
Malicious Call Trace
If a malicious call terminates at a Basic multimedia complex endpoint, the user can dial the
feature access code from the telephone to activate malicious call trace, followed by the
extension of the multimedia endpoint. If the user does not dial the multimedia extension, MCT
traces any call held on the telephone.
Message Waiting
Message Waiting indication is handled at the telephone. Because H.320 calls are converted to
voice before going to coverage, all messages are voice only.
Night Service
Incoming Basic mode data calls follow established night-service processing for data calls.
Remote Access
Communication Manager does not prevent Basic multimedia complexes from attempting to use
remote access. However, these Basic mode endpoints will most likely not be able to dial the
necessary codes.
Station Hunting
Basic mode data calls to endpoints that have an extension administered in the Hunt-to-station
field hunt based on established hunting criteria. The call is converted to voice before station
hunting.
Tenant Partitioning
Permission to make multimedia calls or add parties of any type to a conference is subject to
standard tenant-partitioning restrictions.
