Call Forwarding

48

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:

•

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.

•

If your system admits 1–5 personal profiles, design the different 

profiles to fit your most frequently used positions.
Make sure you use as few answering positions as possible for 

each profile. Profile examples:
