Norstar VoIP Gateway Configuration Guide
EnableTransfer 0 - Disable Call Transfer (default)
1 - Enable call transfer service (H.450.2)
A transfer is initiated at the VoIP Gateway by using a HookFlash. If this service is
enabled, the remote party will perform the call transfer.
EnableForward 0 - Disable call forward (default)
1 - Enable call forward service (H.450.3).
If you enable Call Forward, a "Call forward table" must be used to define call
forward modes (see the ForwardInfoX parameter).
ForwardInfoX a,b,c
x - Gateway port number (1 to 24)
a - Call forward mode
0 - not in use
1 - On busy
2 - Immediate forward
3 - No reply for time "c"
b - Forwarded number
c - Timeout [sec] for no reply
Incoming IP to Telephone call will be forwarded to "b" number on one of the
conditions: busy, immediate or no reply.
IsFaxUsed 0 = No
1 = Fax is send/received using H.323 Annex D T.38 procedure.
DetFaxOnAnswerTone 0 = Receiving Gateway initiates T.38 on receiving HDLC preamble signal from
Fax (default)
1 = Receiving GW initiates T.38 on receiving of CED answer tone from Fax.
ChannelToFax# Type of H.323 (annex D) FAX channel
0 = Voice only
1 = Fax only (can be used only with Fast Start or Tunneling)
2 = Voice + Fax (default)
Example: ChannelToFax3 = 1 (use port ‘3’ only for Fax)
‘IsFaxUsed’ parameter should be set to ‘1’ in order to use the H.323 Fax
according to Annex D T.38.
When channel is set to 2 (Voice + Fax), at beginning of a call, the logical channel
is opened as Voice channel, and after Fax detection, the channel is reopened as
Fax T.38 channel.
This parameter can appear up to 4 times.
Prefix Mapping phone number to IP address, using phone number prefix
Example: Prefix = 20,10.2.10.2
Any dialed number that starts with “20” is routed to IP address “10.2.10.2”.
This parameter is needed when a Gatekeeper is not used.
Can appear up to 20 times. Maximal prefix size is 7 digits
PSTNPrefix a,b
a - destination number prefix (for IP to telephone calls)
b - Hunt group ID
Outgoing IP to Telephone calls starting with "a" will be routed to Hunt group "b".
IsDialNeeded 0 = no dial needed (automatic dialing)
1 = dial needed (default)
If 0 = TargetOfChannel parameters define the automatic dialed number.
If "DialisNeeded =1" the VoIP Gateway seizes the line (after detecting the ringing
signal), plays a dial tone, collects DTMF digits and sends Setup to IP
destination.
