Norstar VoIP Gateway Configuration Guide
DefaultNumber Phone number
VoIP Gateway dials this number if the SETUP message is received with no
phone number.
The DefaultNumber must be one of the phone numbers of the end points.
IsH323IDUsed 0 = The VoIP Gateway encodes the calling and called phone number into e.164
field (default)
1 = The VoIP Gateway encodes the destination phone number in e.164 and
source phone number in H.323-ID fields.
2 = The VoIP Gateway encodes the source phone number in e.164 and
destination phone number in H.323-ID fields.
3 = The VoIP Gateway encodes the calling and called phone number into
H.323-ID field.
EnableQ931Cause 0 - H.225 Release reason will be sent in the Release Complete H.323 message
(default)
1 - Q.931 cause will be send in Release Complete message
IsSetupAckUsed 0 = On receiving of Setup Ack message, VoIP Gateway releases the Call
(default)
1 = On receiving of Setup Ack message, the call is not released.
When working in non-overlap mode (‘IsOverlapUsed = 0’), use this parameter to
enable receiving of Setup Ack messages.
This parameter is used for specific, non-standard applications. Usually when
working in non-overlap mode, the Setup Ack messages are not sent.
OpenH245onFS 0 = Don’t open H.245 channel of Fast Start (default)
1 = H.245 channel is opened immediately after Fast Start connection is
established.
Opening of H.245 channel may be needed for relaying DTMF digits over H.245
channel during a call.
IsDTMFUsed 0 = not used (default)
1 = DTMF digits are sent over H.245 channel using Facility message
Incoming facility messages of out-of-band DTMF is played into FXS or FXO
channels.
For using out of band DTMF, the User must disable inband DTMF by setting:
‘DTMFTransportType = 0’ (erase digit and don’t relay).
Note that this feature is not supported when using Fast Start, unless other party
opens H.245 channel.
IsHookFlashUsed 0 = not used (default)
1 = Send H.245 User Input Indication message, when a hookflash is detected
The received facility message with a HookFlash signal generates HookFlash at
the channel
Is931MsgUsed 0 = not used (default)
1 = DTMF digits and HookFlash signal is sent in H.225/Q.931 info message
(keypad facility)
Note that incoming Q.931 DTMF digits and HookFlash are always ignored.
To use H.225/Q.931 messages, set the following parameters:
‘IsDTMFUsed = 0’ and ‘IsOverlapUsed = 0’
IsSpecialDigits 0 = not used (Default)
1 = Allows user to dial “*” and “#”, and allows endpoint telephone number to
contain such digits.
Notes:
a. When this feature is activated, “#” can not be used to end the dialed number.
b. # and * can be used as first digit of dialed number, disregard the value of
"IsSpecialDigits" parameter.
