Clip No Screening

Attention

Exceptions: In some countries, only the official main number is signalled due to legal regulations.

A number of functions in conjunction with AnyDevice are closely interwoven with the display of telephone numbers. Clip no screening enables the company to signal a caller’s number to an external party other than its own company number. This enables the XPhone Connect Server to transfer the caller’s number to an AnyDevice user.

Specifically, these cases are:

  1. Callback to own device when setting up a call with AnyDevice.

  2. Display of the personal call number to the called party when a call is set up via AnyDevice.

  3. Display the caller’s phone number when the caller calls the personal phone number and is connected to the AnyDevice via the XPhone Call Controller (XCC).

Case 3 is a special case here, as a call number must be signalled that does not originate from the call number range of the own PBX. Restrictions in the public or private signalling system (PBX) may therefore prevent the call number from being set by the XCC in this case.

Hint

Parameters for CLIP configuration for external or internal outgoing calls can be set in the advanced line settings.

Requirements:

The setting of an originating number is influenced in public networks by the Clip No Screening feature. For Clip No Screening to work, the following requirements must be met:

  • The Clip No Screening feature must have been activated for the company by the telephone provider.

  • Clip No Screening must be supported by your voice communication system (PBX).

Configuration

The GwSetting_caller-id-type parameter determines how the Calling Line Identification (CLI) is transferred via SIP. The following settings can be made via the GwSetting_caller-id-type parameter:

System settings > Telephony & Meetings > Telephony > SIP > SIP Gateway Objekt > Advanced Settings

Name

Value

GwSetting_caller-id-type

rpid

Remote Party-Id (Default) IETF reference

pid

P-asserted Identity (see RFC 3325)

none

The phone number is not transferred in any special SIP element.

As there is no uniform standard for signalling the call number, the method that the voice communication system (PBX) used expects must be set.

Tip

If the function does not work as expected, a trace must be created via the XPhone Connect on-board trace mechanism (see Troubleshooting and diagnostics) or a Wireshark trace.
