H.323 User's Manual 5. Web Management
Version 5.0 127 December 2006
Table 5-21: Digital Gateway Parameters (continues on pages 126 to 128)
Parameter Description
Swap Redirect and Called Numbers
[SwapRedirectNumber]
0 = Don't change numbers (default)
1 = Incoming ISDN call that includes redirect number (sometimes referred
as ‘original called number’) uses this number instead of the called
number.
Enable Transfer Capability
[EnableTransferCap]
0 = Disable (default)
1 = Enable.
When disabled, Transfer Capability field sent in Q.931 messages is equal
to ‘Audio 3.1 kHz’. If enabled the Transfer Capability parameter is based
on ‘interworking’ between H.323/Q.931 and ISDN/Q.931 protocols.
Note: This parameter affects both directions (IPÆTel and TelÆIP).
MFC R2 Category
[R2Category]
MFC R2 Calling Party Category (CPC). The parameter provides
information on calling party such as National or International call, Operato
r
or Subscriber and Subscriber priority. The parameter range is 1 to 15,
defining one of the MFC R2 tones.
Disconnect Call on Detection of Busy
Tone
[DisconnectOnBusyTone]
0 = Do not disconnect call on detection of busy tone
1 = Disconnect call on detection of busy tone (default).
This parameter is applicable to CAS & ISDN protocols.
Enable TDM Tunneling
[EnableTDMoverIP]
0 = Disabled (default).
1 = TDM Tunneling is enabled.
When TDM Tunneling is enabled, the originating Mediant 1000
automatically initiates H.323 calls from all enabled B-channels belonging
to the E1/T1/J1 spans that are configured with the ‘Transparent’ protocol.
The called number of each call is the internal phone number of the
B-channel that the call originates from. The IP to Trunk Group routing
table is used to define the destination IP address of the terminating
Mediant 1000. The terminating Mediant 1000 gateway automatically
answers these calls if its E1/T1 protocol is set to ‘Transparent’
(ProtocolType = 5).
Send Screening Indicator to IP
[ScreeningInd2IP]
The parameter can overwrite the calling number screening indication for
ISDN TelÆIP calls.
-1 = not configured (interworking from ISDN to IP) or set to 0 for CAS.
0 = user provided, not screened.
1 = user provided, verified and passed.
2 = user provided, verified and failed.
3 = network provided.
Note: Applicable only if Remote Party ID (RPID) header is enabled.
Send Screening Indicator to ISDN
[ScreeningInd2ISDN]
Overwrites the screening indicator of the calling number for IPÆTel
(ISDN) calls.
-1 = Not Configured (interworking from IP to ISDN) (default).
0 = User provided, not screened.
1 = User provided, verified and passed.
2 = User provided, verified and failed.
3 = Network provided.
PSTN Alert Timeout
[PSTNAlertTimeout]
Alert Timeout in seconds (ISDN T301 timer) for outgoing calls to PSTN.
The default is 180 seconds. The range is 0 to 240.
Note: The PSTN stack T301 timer can be overridden by a lower value,
but it can’t be increased.
Add IE in SETUP
[AddIEinSetup]
This parameter enables to add an optional Information Element data (in
hex format) to ISDN SETUP message.
For example: to add the following IE: ‘0x20,0x02,0x00,0xe1’, define:
‘AddIEinSetup = 200200e1’.
Note: This IE is sent from the Trunk Group IDs defined by the parameter
‘SendIEonTG’.
