it possible to activate or cancel the corresponding forwarding. Furthermore, the icon or
LED associated with this key, indicates when a forwarding is activated. All the
preprogrammed or fixed keys are such keys
- The same station may have a "personal call forwarding" Master key and a "Group call
forwarding" Master key
- A "text answering" forwarding can only be activated on a station with a display
- The "internal" type of calls to be forwarded includes internal calls as well as those coming
from the private network
- Forward to text answering: when a network call from a station without UUS capability (a Z
station for example) arrives at a station that has activated forwarding to text answering, the
call is forwarded to the attendant station, which also receives the text message from the
called station
- Prefixes for the forwarding functions in the numbering plans. The basic value may differ
according to the local version of the software; the following values apply in France:
• Forwarding: base 0 = cancel forwarding
• Forwarding: base 1 = immediate forwarding
• Forwarding: base 2 = forwarding on busy
• Forwarding: base 3 = do not disturb
• Forwarding: base 4 = forward to pager
• Forwarding: base 5 = group call forwarding
• Forwarding: base 6 = disconnect from group
• Forwarding: base 7 = rejoin group
• Forwarding: base 8 = follow-me
• Forwarding: base 9 = cancel follow-me
• Forwarding: base 10 = selective forwarding
- Cascade forwarding (available from version R2.0): a call may be subject to a maximum of
5 individual forwardings (default: 5; configurable by OMC):
• In case of external forwarding (of a local call, of an incoming call by joining or by
re-routing), the cascade may use public or private, analog or digital lines
• The cascade stops as soon as the authorized number is reached (thus avoiding loops)
• The cascade stops when it comes to a user in forwarding:
• Do Not Disturb
• Text answering
• Follow-me
• On the person search device
• Dynamic routing (except if routing is to an external destination)
• Screening: if the last forwarding authorized by the cascade number configuration
concerns a user in the process of screening, this additional forwarding is accepted
• Group call forwarding: if the recipient of group call forwarding is himself forwarded, this
forwarding will not be processed
• Forwarding on busy: the forwarding is processed even if the user is grade 2 busy (2
established calls)
• Forwarding on the person search device: this forwarding is processed even if it means
exceeding the authorized number of cascades
- US special features: a “Do not disturb” forwarding is managed as an immediate forwarding
