releases the call and sends a SIP 500 "Server Internal
Error” response.
Web: Time to Wait before Dialing
[msec]
EMS: Time Before Dial
[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, EnableDIDWink is set to 1).
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 value is 1,000 (i.e., 1 second).
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 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.
This parameter is typically set to between 5 and 8. The default
is 8.
Notes:
This 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).
Web: Rings before Detecting Caller
ID
EMS: Rings Before Caller ID
[RingsBeforeCallerID]
Determines the number of rings before the device starts
detecting Caller ID.
[0] 0 = Before first ring.
[1] 1 = (Default) After first ring.
[2] 2 = After second ring.
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.
Note: 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.
