Mediant 800 Gateway & E-SBC | User's Manual
Description
Enables the device to ignore ISDN Disconnect
messages with Progress Indicator (PI) information
element (IE) values 1 or 8.
■ [1] = The call (in connected state) is not released
if a Q.931 Disconnect with PI (PI = 1 or 8)
message is received during the call.
■ [0] = (Default) The call is disconnected.
Defines if and which Progress Indicator (PI)
information element (IE) is added to the sent ISDN
Setup message. Some ISDN protocols such as NI-2
or Euro ISDN can optionally contain PI = 1 or PI = 3
in the Setup message.
■ [0] = PI is not added (default).
■ [1] = PI 1 is added to a sent ISDN Setup
message - call is not end-to-end ISDN.
■ [3] = PI 3 is added to a sent ISDN Setup
message - calling equipment is not ISDN.
Defines the value of the Progress Indicator (PI)
information element (IE) that if present in the received
ISDN Progress message, the device sends SIP 180
messages without an SDP body (for Tel-to-IP calls).
The valid value is a bit field, allowing you to specify
more than one PI. The default is 0, meaning that SDP
is included in the outgoing SIP 180 message,
regardless of PI value.
Defines the ISDN B-channel negotiation mode.
■ [0] Preferred
■ [1] Exclusive (default)
■ [2] Any
Note:
■ For some ISDN variants, when 'Any' (2) is
selected, the Setup message excludes the
Channel Identification IE.
■ The Any' (2) option is applicable only if the
following conditions are met:
✔
The parameter TerminationSide is set to 0
('User side').
✔
The PSTN protocol type (ProtocolType) is
configured as Euro ISDN.
Determines the bit map for special PSTN behavior
parameters:
■ [0] = (Default) Applicable for NI-2 ISDN and
