Main goal
The goal is, to reach this HFA IP phones in their new logon location via tie trunk
access under their individual (modified) extension numbers and the HFA IP phones will
be
supplied with MWI update information of the Xpressions server.
The MWI led will be
switched on or switched off at the HFA subscriber. The HFA subscriber now has the
possibility to call the Xpression server from the alternate OpenScape 4000 via tie
trunk
access in order to pick up its voice messages.
If the HFA subscriber has different
numbers in default node and alternate node, it may be necessary to use the mailbox
number
of the default node also when picking up the voice messages out of alternate
node.
Alternate Routing on Error via tie trunks to another OpenScape 4000 should be
used very restrictive. Furthermore, the administration should only done subscriber
individual and not source group related.
Administration
In the node with Xpression allocation, following administration has to be
done:
- For HFA subscriber, it is necessary to set a mark for moving logon location
CHANGE-SDAT:STNO=4711, TYPE=DATA1, MVHFAIP=YES;
- In order to avoid network loops, it is necessary to set the partner gateway IP address
for that sourcegroup, that is allocated to the related HFA
subscribers.
ADD-APRT:TYPE=ALTERR, SRCGRP=1, ALRTYPE=OOS, GWIPADR=<ip_address_of_gw>;
- For the HFA subscriber, it is necessary to administer an alternate routing destination
number, which leads via tie trunk to an alternate OpenScape 4000 node.
ADD-SDAT:STNO=4711, TYPE=DATA1, STNOOOS=723-4711;
- There is an other possibility, to administer an alternate routing destination number
for the complete source group, the HFA subscriber is a member of (not recommended).
ADD-APRT:TYPE=ALTERR, SRCGRP=1, ALRTYPE=OOS, ALTRTNR=723, GWIPADR=<ip_address_of_gw>, EXTNO=4;
In the node, to which the alternate routing on error points, following administrations
have to be done:
It is necessary to install a relation between subscriber and
XPRESSION. In this case, the subscriber is that number with what the HFA subscriber
from
the node with the XPRESSION is logged on in the alternate node.
CREATE-RICHT:MODE=PM,IDX=1, SAN=nnnnn, NAME=PHONEMAIL;
CHANGE-SBCSU: STNO=4711, PMIDX=1;
Interdependencies
with other Requests:
Alternate routing on error for MWI uses the functionality of
common Alternate routing on error for HFA phone, that can change its logon location
in
case of IP quality problems (loss of LAN connection etc.) This means, that this feature
only can be used, if the basic Alternate routing on error works also fine.
