TargetOfChannel### Automatic dialed phone number.
The automatic dialed number, used if OFF HOOK or ringing signal is detected.
Applicable when IsDialNeeded = 0.
Its format: “TargetOfChannel<channel> = <number>”.
Example: “TargetOfChannel1 = 123”
The parameter, if used, should be defined per port (channel)
IsUseFreeChannel 0 = Select the channel according to destination phone number received in H.225
setup message, (default)
1 = Select the next available channel
Used for IP
Æ
VoIP Gateway calls
The next available 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 VoIP Gateway selects the next free channel, and dials
into the line the destination phone number received in Setup message.
IsTwoStageDial 0 = One stage dialing
1 = Two Stage Dialing (default)
Used for IP
Æ
VoIP Gateway calls
For ‘Two Stage Dialing the VoIP Gateway 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’ VoIP Gateway 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.
IsWaitForDialTone 0 = don’t wait for dial tone
1 = Wait for dial tone (default)
Used for ‘One Stage Dialing’.
If IsWaitForDialTone = 0, VoIP Gateway dials phone number immediately after
seizing the PSTN/PBX line, without ‘listening’ to dial tone.
If IsWaitForDialTone = 1, VoIP Gateway dials phone number only after it detects
a dial tone (it can take 3-5 sec to detect a dial tone).
The correct dial tone parameters should be configured in call progress tone file.
FXOWaitForDialTime Dialing timeout [in msec], after seizing the line and before start dialing. (Default
=1000)
Applicable for single stage dialing.
EnableSilenceDisconnect If enabled, the VoIP Gateway will disconnect the call if silence is detected for
120seconds (default)
FarEndDisconnectPeriod Duration of Silence period [in seconds] for call disconnection. (Default = 120)
Applicable for VoIP Gateways that are using DSP template = 3 or 4.
MaxDigits 2 to 19 (default 4). Maximum number of digits that can be dialed.
Dialing ends when maximum number of digits dialed or timeout between digits
expired (TimeBetweenDigits parameter), or ‘#’ is dialed.
TimeBetweenDigits 0 to 5 (default 4) Inter-digit timeout in seconds, used to terminate dialed
numbers.
IsSETUPIncludeNum 0 = Send an empty SETUP (or GK ARQ) message, without called party number.
1 = Do not send an empty setup message (default)
