Parameter Description
Web: Ring Detection
Timeout [sec]
EMS: Timeout Between
Rings
[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 deviceinitiates 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.
This parameter is typically set to between 5 and 8. The default is 8.
Notes:
ƒ
This parameter is applicable only to FXO interfaces (for Tel-to-IP
calls).
ƒ
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).
Web: Rings before
Detecting Caller ID
EMS: Rings Before Caller
ID
[RingsBeforeCallerID]
Determines the number of rings before the device starts detecting
Caller ID.
ƒ
[0] 0 = Before first ring.
ƒ
[1] 1 = After first ring (default).
ƒ
[2] 2 = After second ring.
Note: This parameter is applicable only to FXO interfaces.
Web/EMS: Guard Time
Between Calls
[GuardTimeBetweenCalls]
Defines the time interval (in seconds) after a call has ended and a new
call can be accepted for IP-to-Tel (FXO) calls.
The valid range is 0 to 10. The default value is 1.
Notes:
ƒ
Occasionally, after a call ends and on-hook is applied, a delay is
required before placing a new call (and performing off-hook). This is
necessary to prevent incorrect hook-flash detection or other glare
phenomena.
ƒ
This parameter is applicable only to FXO interfaces.
