[ISDNSuppServ_IsPresentationR
estricted]
Determines whether the endpoint sends its Caller ID information
to the IP when a call is made.
 [0]
Allowed = The device sends the string defined in the 'Caller
ID' field when this endpoint makes a Tel-to-IP call.
 [1] Restricted = The string defined in the 'Caller ID' field is not
sent.
26.15 Detecting Collect Calls
The device detects collect calls (reverse charge calls) using any of the following
information elements (IE) in the received Q.931 ISDN Setup message for Tel-to-IP calls:
 Reverse Charging Indication IE
 Facility IE
When the device detects a collect call, it adds a proprietary header (X-Siemens-Call-Type:
collect call) to the outgoing SIP INVITE message.
No special configuration is required for the feature.
Note: The feature is applicable only to the Euro ISDN protocol variant.
26.16 Advice of Charge Services for Euro ISDN
Advice of charge (AOC) is a pre-billing function that tasks the rating engine with calculating
the cost of using a service and relaying that information back to the customer (caller). This
allows users to obtain call charging information during the call (AOC-D) or at the end of the
call (AOC-E).
The AOC messages are sent in the EURO ISDN Facility Information Element (IE)
message. The device interworks these ISDN messages with SIP by converting the AOC
messages into SIP INFO (during call) and BYE messages (end of call) using AudioCodes
proprietary SIP AOC header, and vice versa. The device supports both currency (monetary
units) and pulse (non-monetary units) AOC messages.
This feature can typically be implemented in the hotel industry, where external calls made
by guests can be billed accurately. In such a setup, the device is connected on one side to
a PBX through an ISDN line (Euro ISDN), and on the other side to a SIP trunk provided by
an ITSP. When a call is made by a guest, the device first sends an AOC-D Facility
message to the PBX indicating the connection charge unit, and then sends subsequent
AOC-D messages every user-defined interval to indicate the charge unit during the call.
When the call ends, the device sends an AOC-E Facility message to the PBX indicating the
total number of charged units.
Note: The feature is applicable only to Euro ISDN (PRI and BRI).
