Call Forwarding
Dialog 4420 IP Basic 36
Important notes when designing your search profiles:
•
Avoid ring times longer than 45 seconds for your profiles.
Usually the caller hangs up after 3-6 ring signals. If you need a
longer ring time, the maximum time is 60 sec.
• Consider the time you need to react and answer on each
answering position in your profile.
You might need up to 15 seconds to react and answer a call on
a desk or cordless phone and 20–25 seconds for a mobile
phone.
• There must be an answering position at the end of every profile
(Voice Mail or operator/secretary).
If not, calls might end up unanswered.
• Consider what should happen while you are busy on a phone.
The available options are:
– Activate Free on 2nd (if available)
– Follow-me to Voice Mail
– Follow-me to the operator
• If an answering machine, a fax or other answering device is
used as an early answering position, it might interrupt the
searching.
Disconnect the answering device, or design the ring times so
they do not affect the searching.
• If your system admits just one single personal profile, design the
profile only with your 2–3 most frequently used positions.
If you add more numbers, there is a risk that the caller hangs up
before a latter position is called.
• Make sure you use as few answering positions as possible for
each profile. Profile examples:
– In office
– At home
– Traveling
– Absent/not reachable
