The handling of collect calls can be configured with various parameters per trunk
group, per user group, and per user:

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.
