Table 5-33: FXO Parameters (continues on pages 127 to 130)
Parameter Description
Waiting For Dial Tone
[IsWaitForDialTone]
No
[0] = Don’t wait for dial tone.
Yes
[1] = Wait for dial tone (default).
Used for IPÆMediaPack/FXO gateways, when ‘One Stage Dialing’ is enabled.
If ‘wait for dial tone’ is enabled, the FXO gateway dials the phone number (to the
PSTN/PBX line) only after it detects a dial tone.
Note 1: The correct dial tone parameters should be configured in the Call
Progress Tones file.
Note 2: 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).
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.
Time to Wait before Dialing
[msec]
[WaitForDialTime]
Note: Replaces the
obsolete parameter
FXOWaitForDialTime.
Determines the delay before the gateway starts dialing on the FXO line in the
following scenarios (applicable only to FXO gateways):
1. The delay between the time the line is seized and dialing is begun, during the
establishment of an IPÆTel call.
Note: Applicable only to FXO gateways for single stage dialing, when waiting for
dial tone (IsWaitForDialTone) is disabled.
2. The delay between the time when Wink is detected and dialing is begun, during
the establishment of an IPÆTel call (for DID lines, EnableDIDWink = 1).
3. For call transfer. The delay after hook-flash is generated and dialing is begun.
The valid range (in milliseconds) is 0 to 20000 (20 seconds). The default value is
1000 (1 second).
Ring Detection Timeout
[sec]
[FXOBetweenRingTime]
Note: Applicable only to FXO gateways for TelÆIP calls.
The Ring Detection timeout is used differently for normal and for automatic dialing.
If automatic dialing is not used, and if Caller ID is enabled, then the FXO gateway
seizes the line after detection of the second ring signal (allowing detection of caller
ID, sent between the first and the second rings). If the second ring signal doesn’t
arrive for ‘Ring Detection Timeout’ the gateway doesn’t initiate a call to IP.
When automatic dialing is used, the FXO gateway initiates a call to IP when
ringing signal is detected. The FXO line is seized only if the remote IP party
answers the call. If the remote party doesn’t answer the call and the ringing signal
stops for ‘Ring Detection Timeout’, the FXO gateway Releases the IP call.
Usually set to a value between 5 and 8.
The default is 8 seconds.
Reorder Tone Duration [sec]
[TimeForReorderTone]
Busy or Reorder tone duration (seconds) the FXO gateway plays before releasing
the line.
The valid range is 0 to 100. The default is 0 seconds.
Usually, after playing a Reorder / Busy tone for the specified duration, the FXS
gateway, starts playing an Offhook Warning tone.
Note 1: Selection of Busy or Reorder tone is performed according to the release
cause received from IP.
Note 2: Refer also to the parameter ‘CutThrough’ (described in Table 5-8).
Answer Supervision
[EnableVoiceDetection]
Yes
[1] = FXO gateway sends 200 OK (to INVITE) messages when
speech/fax/modem is detected.
No [0] = 200 OK is sent immediately after the FXO gateway finishes dialing
(default).
Usually this feature is used only with early media establish voice path before the
call is answered.
Note: This feature is applicable only to ‘One Stage’ dialing.
Rings before Detecting
Caller ID
[RingsBeforeCallerID]
Sets the number of rings before the gateway starts detection of Caller ID (FXO
only).
0 [0] = Before first ring.
1
[1] = After first ring (default).
2
[2] = After second ring.
