Valid Range and Description
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: ChannelToFax7 = 1 (use port ‘7’ of MP-108 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 8 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”.
Needed when Gatekeeper is not used.
Can appear up to 20 times. Maximal prefix size is 7 digits
PSTNPrefix
(IP to Trunk group routing
table)
a,b
a – destination number prefix (for IP!Tel calls)
b – Hunt group ID
Outgoing IP!Tel calls starting with "a" will be routed to Hunt group "b"
IsDialNeeded
(Enable Automatic Dialing)
0 = no dial needed (automatic dialing)
1 = dial needed (default)
If 0 = TargetOfChannel parameters define the automatic dialed number.
This parameter is applicable for both FXS and FXO Gateways.
If "DialisNeeded =1" the FXO Gateway will seize the line (after detecting the ringing
signal), play a dial tone, collect DTMF digits and send Setup to IP destination.
TargetOfChannel#
(Automatic Dialing Table)
Automatic dialed phone number.
The automatic dialed number, used if OFF HOOK detected in FXS channel, or ringing
signal is detected in FXO channel.
Applicable when IsDialNeeded = 0.
Its format: “TargetOfChannel<channel> = <number>”.
Example: “TargetOfChannel1 = 123”
The parameter, if used, should be defined per Gateway FXS or FXO port (channel)
IsUseFreeChannel
(Selects Next Available
Channel)
0 = Select the FXO channel according to destination phone number received in H.225
setup message, (default)
1 = Select the next available FXO channel
Used for IP! MP-1xx/FXO calls
The next available FXO channel is selected, out of the Gateway channels defined in
‘ChannelList’ and Channel2Phone’ parameters.
When using one stage dialing, (‘IsTwoStageDial =0’), ‘IsUseFreeChannel’ should be
equal to ‘1’.
For one stage dialing the MP-1xx/FXO selects the next free channel, and dials into the
FXO line the destination phone number received in Setup message.
IsTwoStageDial
0 = One stage dialing
1 = Two Stage Dialing (default)
Used for IP ! MP-10x/FXO calls
For ‘Two Stage Dialing the MP-10x/FXO seizes the PSTN/PBX line, without performing
any dial, the remote User is connected over IP to PSTN/PBX, and all further signaling
(dialing and call progress tones) is done directly with the PBX without Gateway
intervention.
For ‘One Stage Dialing’ MP-10x/FXO seizes the next available channel
(‘IsUseFreeChannel’ should be ‘1’), and dials the destination phone number received in
Setup message. Use the ‘IsWaitForDialTone’ parameter to specify whether the dialing
should come after detection of dial tone, or immediately after seizing of the line.
