Tab. 42 Handling collect calls: Trunk group configuration
Note:
When incoming calls arrive via SIP network interfaces, collect calls and
normal calls cannot differentiated. Therefore, the setting Reject all collect
calls rejects collect calls as well as normal calls.
For the trunk group setting Depends on the destination, the following responses ap-
ply:
• The call arrives at a user:
All collect calls are rejected if the parameter Allow collect calls is configured to No
in the user's assigned permission set.
• The call arrives at a system destination which automatically answers the call
(e.g. voice mail system):
All collect calls are rejected.
• For calls from the public ISDN network, the following also applies:
– All collect calls are rejected if the call arrives at a user group whose parameter
Offer collect calls is configured to No.
If the parameter Offer collect calls is configured to Yes, collect calls are offered
to those user group members whose permission set has the parameter Allow
collect calls configured to Yes.
– The call goes to an external destination (e.g. via forwarding or if the call is to a
PISN user):
The external destinations are not called.
Note:
When incoming calls arrive via SIP network interfaces, collect calls and
normal calls cannot differentiated. All calls are handled like collect calls
from the public ISDN network.
