Forwarding in line groups
• If a user who is a member of user group uses CFU to forward to voice mail, the
behaviour is the same as if he had used CFU to external or to a PISN user (see
"Call Forwarding Unconditional (CFU) for user group members", page 147
).
• CFUs to voice mail by line-group members using CFNR do not result in exclusion
from the line group. However the forwarding is always carried out after the con-
figured CFNR delay.
Response to call forwarding chains
If user A activates a Call Forwarding Unconditional to user B, who has himself di-
verted to the voice mail user group, the response depends on the following config-
uration setting made for user A:
• If the parameter
Last mailbox for CFU/CD
is configured to
No
(default setting), a
caller will be connected with the voice mailbox of user A. If user A has not set up
a personal voice mailbox, the caller obtains the global greeting text. This re-
sponse also applies to CFU chains.
• If the parameter
Last mailbox for CFU/CD
is configured to
Yes
, a caller will be con-
nected with the voice mailbox of user B. In CFU chains the user is connected
with the voice mailbox of the last user in the chain.
In QSIG networks or voice mail systems connected via QSIG, the response of param-
eter
Send first/last mailbox information
is dependent on the trunk group settings:
• If the parameter is set to
No
, a call to user A is in any case forwarded to the voice
mailbox of user B or to the voice mailbox of the last user in the chain.
• If the parameter is on
Yes
, the response is dependent on the
Last mailbox on CFU/
CD
setting made with user A.
Forwarding via call distribution element (CDE)
• Situation 1: (possible configuration)
On a CDE 900, voice mail is configured as the destination. User 30 has a personal
mailbox. With CDE 30, user 30 is entered as destination and as CDE 900 overflow.
An external call to a direct dialling number that is linked with CDE 30 is for-
warded to user 30 in the event of overflow.
• Situation 2: (
configuration to be avoided!
)
On a CDE 900, voice mail is configured as the destination. If an external call is
made to a direct dialling number that is linked to CDE 900, the voice mail system
is unable to assign the call to a mailbox and the call is rejected.
