SIP User's Manual 12. Configuration Parameters Reference
12.12.6.3 CAS Parameters
The Common Channel Associated (CAS) parameters are described in the table below.
Note that CAS is not applicable to BRI interfaces.
Table 12-53: CAS Parameters
Parameter Description
Web: CAS Transport Type
EMS: CAS Relay Transport Mode
[CASTransportType]
Controls the ABCD signaling transport type over IP.
[0] CAS Events Only = Disable CAS relay (default).
[1] CAS RFC2833 Relay = Enable CAS relay mode using
RFC 2833.
The CAS relay mode can be used with the TDM tunneling
feature to enable tunneling over IP for both voice and CAS
signaling bearers.
[CASAddressingDelimiters]
Determines if delimiters are added to the received address or
received ANI digits string.
[0] = Disable (default)
[1] = Enable
When this parameter is enabled, delimiters such as '*', '#', and
'ST' are added to the received address or received ANI digits
string. When it is disabled, the address and ANI strings remain
without delimiters.
[CASDelimitersPaddingUsage]
Defines the digits string delimiter padding usage per trunk.
[0] (default) = default address string padding: '*XXX#' (where
XXX is the digit string that begins with '*' and ends with '#',
when using padding).
[1] = special use of asterisks delimiters: '*XXX*YYY*' (where
XXX is the address, YYY is the source phone number, and '*'
is the only delimiter padding).
Note: For this parameter to take effect, a device reset is
required.
Web: CAS Table per Trunk
EMS: Trunk CAS Table Index
[CASTableIndex_x]
Defines the CAS protocol per trunk (where x denotes the trunk
ID) from a list of CAS protocols defined by the parameter
CASFileName_x.
For example, the below configuration specifies Trunks 0 and 1
to use the E&M Winkstart CAS (E_M_WinkTable.dat) protocol,
and Trunks 2 and 3 to use the E&M Immediate Start CAS
(E_M_ImmediateTable.dat) protocol:
CASFileName_0 = 'E_M_WinkTable.dat'
CASFileName_1 = 'E_M_ImmediateTable.dat'
CASTableIndex_0 = 0
CASTableIndex_1 = 0
CASTableIndex_2 = 1
CASTableIndex_3 = 1
Note: You can define CAS tables per B-channel using the
parameter CASChannelIndex.
