Managing multimedia calling
555-233-506350 Issue 5 October 2002
If a plain voice station or a Basic mode complex is the covering party, the
answering voice station will receive audio only. If all voice stations in the
coverage path have the Station screen Early Answer field set to
n and the
originator of the multimedia call was not a local Enhanced mode complex, the
answering station will hear hourglass tone.
If an Enhanced mode complex is the covering party, the answering voice station
will receive voice and video. If all voice stations in the coverage path have the
Station screen Early Answer field set to
n and the originator of the multimedia
call was not a local Enhanced mode complex, the answering station will hear
hourglass tone.
Multimedia calls and off-net call coverage. If the principal station’s coverage
path include a remote coverage point, the multimedia call will cover off-switch as
voice only. If the call is unanswered off-switch and proceeds to the next coverage
point on-switch, the multimedia nature of the call is preserved.
Multimedia calls and coverage to voice mail. Voice mail systems such as
AUDIX are typically the last point in a coverage path and are usually
implemented as a hunt group. In order to guarantee that the originator of an H.320
multimedia call hears the voice mail greeting, the hunt group that defines the list
of voice mail ports should have the Early Answer field on the hunt group set to
y.
This field will have no effect on voice calls to the voice mail system.
Hunt Groups using Enhanced Mode Complexes
When creating hunt groups with Enhanced multimedia mode complexes, only the
station extension should ever be entered as a hunt group member. Any hunt group
or ACD skill can include the voice station of an Enhanced multimedia complex as
a member. The data extension of an Enhanced mode complex should never be
entered as any hunt group member. A hunt group or skill may have a mix of
members that are stand-alone stations and Enhanced mode complex stations. In
order to guarantee that all members of the hunt group or skill can receive voice or
multimedia calls, all members should have the H.320 field on the station screen
set to
y. Simple voice stations will receive voice only. Enhanced mode stations
will receive voice and video.
The MM Early Answer field (on the Hunt Group screen) tells the system to
answer an incoming multimedia call and establish audio before it reaches the first
member of the hunt group. Thus, when the talk path is established, the caller is
able to speak with an agent immediately.
Other considerations. CMS measurements may indicate unusually slow ASA,
because of the time required for the system to establish early-answer before
offering the call to an agent.
