10.2-8 Integration Volume
Trunk Identification
An incoming trunk is identified only by individual trunk number, not by trunk group. This requires that
each trunk to be identified by the Octel 200/300 have its own entry in the Octel 200/300 TRUNK
GROUP Table.
Default Secondary Answering
Call coverage is set up at each phone only. This requires that each phone user set up their extension to
forward to the Octel 200/300 so that the Octel 200/300 can provide secondary answering.
If mailbox holders forward their phones to destinations other than the Octel 200/300, CPI may not work
properly.
.
Phones using MWI should set forwarding to the Octel 200/300 only on ring-no-answer. Refer to
PBX Functional Limitations that affect MWI, in this section.
Applications
Here are application recommendations to help avoid some of the limitations previously described.
Forwarding
Example. The customer has an integrated Mitel system where the Octel 200/300 answers their incoming
lines. The Octel 200/300 releases calls to ringing, so the individual extensions must be forwarded to the
Octel 200/300. The customer has Superset 4 phones and 2500-type phones with message waiting lamps,
and the customer wants to have the Octel 200/300 perform message waiting indication.
Recommendation. Since the Octel 200/300 cannot control a phone's message waiting indicator when
that phone forwards on busy or all-forward, we recommend that phones using MWI be forwarded to the
Octel 200/300 only on ring-no-answer. DID calls require coverage on busy, therefore we do not
recommend using MWI for extensions that receive DID calls. Instead, use the Octel 200/300 ringing
notification for these extensions, and set them to forward on ring-no-answer and busy.
Since extensions using MWI are forwarded on ring-no-answer, they have call coverage for internal and
external calls on ring-no-answer. Although they are not forwarded on busy, they have coverage for
external calls on busy since the Octel 200/300 recognizes the busy condition and reconnects to the caller
with the status "is on the phone" or "doesn't answer. . ." These extensions do not have internal call
coverage when they are busy, but this generally is not a problem since internal callers usually call back
instead of leaving a message.
.
MWI does not work for any station in Do Not Disturb, or for Superset 4 stations with AUTO
ANSWER turned ON.
Hunt Group
Example. A customer service group has five lines in a hunt group, and each line appears on a phone. If
agents in the group forward their phones to the Octel 200/300, their extensions are taken out of the hunt
group, even if the forwarding is only on ring-no-answer.
Recommendation. We recommend assigning two extensions to each hunt group agent — one
extension in the hunt group (not forwarded), and the other, a personal line (forwarded to the Octel
200/300 for call coverage). This requires an additional port in the PBX for each agent. If the agents do
not have multiline phones, this also requires additional phones.
