Table 5-27: FXO Parameters
Parameter Description
Dialing Mode
[IsTwoStageDial]
Used for IP Æ FXO gateways calls.
ƒ
[0]
One Stage = One-stage dialing.
ƒ
[1]
Two Stages = Two-stage dialing (default).
If two-stage dialing is enabled, then the FXO gateway seizes one of the
PSTN/PBX lines without performing any dial, the remote user is connected
over IP to PSTN/PBX, and all further signaling (dialing and Call Progress
Tones) is performed directly with the PBX without the gateway's
intervention.
If one-stage dialing is enabled, then the FXO gateway seizes one of the
available lines (according to the 'Channel Select Mode' parameter), and
dials the destination phone number received in the INVITE message. Use
the 'Waiting For Dial Tone' parameter to specify whether the dialing should
come after detection of dial tone, or immediately after seizing of the line.
Waiting For Dial Tone
[IsWaitForDialTone]
Used for IP Æ FXO gateway.
ƒ
[0]
No = Don't wait for dial tone.
ƒ
[1]
Yes = Wait for dial tone (default).
When 'One Stage Dialing' is enabled and 'Waiting for Dial Tone' is
enabled, the FXO gateway dials the phone number (to the PSTN/PBX line)
only after it detects a dial tone.
If 'Waiting For Dial Tone' is disabled, the FXO gateway immediately dials
the phone number after seizing the PSTN/PBX line, without 'listening' to
dial tone.
Notes:
ƒ
The correct dial tone parameters should be configured in the Call
Progress Tones file.
ƒ
It can take the gateway 1 to 3 seconds to detect a dial tone (according
to the dial tone configuration in the Call Progress Tones file).
Time to Wait before
Dialing [msec]
[WaitForDialTime]
Determines the delay after hook-flash is generated and dialing is begun.
Applies to call transfer (TrunkTransferMode = 3) on CAS gateways.
Determines the delay before the gateway starts dialing on the FXO line in
the following scenarios (applicable only to FXO gateways):
ƒ
The delay between the time the line is seized and dialing is begun,
during the establishment of an IP
Æ Tel call.
Note:
Applicable only to FXO gateways for single stage dialing, when
waiting for dial tone (IsWaitForDialTone) is disabled.
ƒ
The delay between the time when Wink is detected and dialing is
begun, during the establishment of an IP
Æ Tel call (for DID lines,
EnableDIDWink = 1).
ƒ
For call transfer. The delay after hook-flash is generated and dialing is
begun.
The valid range (in milliseconds) is 0 to 20,000 (i.e., 20 seconds). The
default value is 1,000 (i.e., 1 second).
