Coverage
Multimedia calls to an Enhanced mode complex are subject to the same coverage criteria as voice calls
and follow the coverage path administered for the voice Station of the Enhanced multimedia mode
complex.
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
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.
