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 screen 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 might 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 can indicate unusually slow ASA, because of the time required for the
system to establish early-answer before offering the call to an agent.
