1. Divert a call to a second number.

Detour code U
U= 21 always, U= 61 delayed, U= 62 not attainable, U= 67 engaged
U= 61, 62, 67 can be activated parallel.
U= 21 no bell and overwrites U= 61, 62 und 67

Service code D

Input without * D means redirect all services D

Turn off a detour:

# # 002 # send (all U and D)
# # 004 # send (only U= 61, 62, 67 and all D)
# # U * * D # send (individual U and D)
without * * D all services D of U are eliminated.

Query a detour:

* # U * * D # send (without * * D all services D of U are asked)

Redirect to the call or fax box:
* * U * number * D # send. With D=11 for call box or D=13 for fax box.
