CLIP no screening
Requirements:
• CLIP no screening service feature supported and enabled by the network provider
• Type of number presentation configured for the VoIP provider In accordance with RFC
3325 with P-Asserted-Identity or In accordance with RFC 3325 with P-Preferred-
Identity
The exchange line transfers the customer-specific phone number (e.g. a service phone
number) entered in Phone number for CLIP no screening to the call destination without
checking that this number is correct.
Notes:
In Germany, some providers only offer this service feature for PTP connec-
tions. The CLIP no screening function for VoIP connections also depends on
which provider is being used.
When an emergency number is dialled, the phone number received from the
network provider is always transmitted, not the phone number you specified
yourself.
However, the correct phone number is also still transferred to the exchange
line, but this cannot be viewed by the person being called.
CLIP no screening must be enabled for every connection to ensure that the
phone number for CLIP no screening is transmitted instead of the phone
number received from the network provider.
Use CLIP no screening for call forwarding
Requirements:
• CLIP no screening switched on for the VoIP account
If a call is forwarded via the external connection, the caller's phone number is sent to the
destination of the forwarded call.
The PBX's phone number is sent to the destination of the forwarded call.
Extension (DDI number)
If you want an extension number to be different from the ones used in linear call distribution, or
if an extension number is needed for a different function (e.g. remote configuration, CLIP no
screening), you must also enter it in the phone number list (click on
all the extension numbers for a PTP connection that is not running linear call distribution.
