No special AMO configuration is necessary.
OpenScape Contact Center timer for ring no answer must be lower than
no call transfer parameter NOCALLTR in OpenScape 4000.
Both timers (in OpenScape 4000 and OpenScape Contact Center) have
the default value equal with 30. This leads to the following behavior:
When the call comes back from ISDN it is transferred to attendant console
and it is not routed to Call Director.
In OpenScape 4000 the parameter can be changed using the following
AMO command:
e.g. CHANGE-CTIME:TYPESWU=TRK,NOCALLTR=35;
The instruction to change the timer in OpenScape Contact Center can
be found in OpenScape Contact Center Enterprise V8 R2, Manager Administration
Guide, Administrator Documentation > Section 8.3.2.
