CHAPTER68 Configuration Parameters Reference
Mediant 1000 Gateway & E-SBC | User's Manual
Parameter Description
■ The device may take 1 to 3 seconds to detect a dial
tone (according to the dial tone configuration in the
CPT file). If the dial tone is not detected within 6
seconds, the device releases the call and sends a
SIP 500 "Server Internal Error” response.
'Time to Wait before Dialing'
configure voip > gateway
analog fxo-setting >
time-wait-b4-dialing
[WaitForDialTime]
Defines the delay before the device starts dialing on the
FXO line in the following scenarios:
■ The delay between the time the line is seized and
dialing begins during the establishment of an IP-to-
Tel call.
Note: Applicable only for one-stage dialing when the
parameter IsWaitForDialTone is disabled.
■ The delay between detection of a Wink and the start
of dialing during the establishment of an IP-to-Tel
call (for DID lines, see the EnableDIDWink
parameter).
■ For call transfer - the delay after hook-flash is
generated and dialing begins.
The valid range (in milliseconds) is 0 to 20,000 (i.e., 20
seconds). The default is 1,000 (i.e., 1 second).
'Ring Detection Timeout'
configure voip > gateway
analog fxo-setting >
ring-detection-tout
[FXOBetweenRingTime]
Defines the timeout (in seconds) for detecting the
second ring after the first detected ring.
If automatic dialing is not used and Caller ID is enabled,
the device 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
is not received within this timeout, the device doesn't
initiate a call to IP.
If automatic dialing is used, the device initiates a call to
IP when the 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 second ring
signal is not received within this timeout, the device
releases the IP call.
The parameter is typically set to between 5 and 8. The
default is 8.
Note:
■ The parameter is applicable only for Tel-to-IP calls.
■ This timeout is calculated from the end of the ring
until the start of the next ring. For example, if the ring
cycle is two seconds on and four seconds off, the
timeout value should be configured to five seconds
(i.e., greater than the off time, e.g., four).
'Rings before Detecting Caller ID'
configure voip > gateway
analog fxo-setting >
rings-b4-det-callerid
Determines the number of rings before the device starts
detecting Caller ID.
■ [0] 0 = Before first ring.
■ [1] 1 = (Default) After first ring.
