The VIP number list “
VIP numbers
” contains GSM phone numbers that get a special
treatment. Each line contains a phone number and may also contain an MSN in the
format <GSM number>/<MSN>. The MSN may be used to define short numbers for
the members of the VIP list. If this MSN is called from any source (i.e. NT, TE or
GSM), the call is connected to the associated GSM phone number. If a call comes in
from a VIP number, the associated MSN is transmitted as calling party number in the
ISDN messages.
VIP users always have the right to dial in even if the channel’s dial in option is
switched off (“Call Default”, see 3.3.14). This allows to define a specific user group
that may dial any number while normal users only call the default extension.
VIP users also use the routing function (see 3.3.4). While normal users calling from
GSM are always connected to the PBX, VIP users may also call to PSTN or GSM
depending on the called number and the programmed routing.
If a VIP number is called, the calling party number (the number belonging to the SIM
card) is always shown to the VIP user, even if the channel in use has the option CLIR
enabled, thus suppressing the number presentation. This does not enable the use of
the return call handling in this case, because then a VIP won’t be able to use the
VPBX anymore if a return call is stored for him.
The functions of the virtual PBX are also accessible to VIP users (see 3.3.12). Thus
all GSM users contained in this list can use all functions normally available only to
PBX extensions. Therefore these phone numbers are also called virtual extensions.
Note:
The device uses the country and area code settings for the GSM number so
that only one notation of a number need to be entered in the list.
