Proxy-Require
SIP Extension to notify SIP server that the unit is behind the NAT/Firewall.
Use NAT IP
NAT IP address used in SIP/SDP message. Default is blank.
Ring Timeout
Default value is
60 Sec.
Incoming call will stop ringing when not picked up given a specific
period of time.
Hunting Group Ring
Timeout
Default value is
20 Sec.
If call is not answered within this designated time period, the
callwill be forwarded to the next member of a Hunt Group.
Hunting Group Type
Linear, Circular, parallel and Shared line. Default is
Circular.
Linear style will sort the call
to the lowest-numbered available line; this is also called “serial hunting”. Circular style will
distribute the calls "round-robin". If a call is assigned to line 1, the next call goes to 2 and
the next to 3. The succession throughout each of the lines continues even if one of the
previous lines becomes available. When the end of the hunt group is reached, the hunting
starts over at the first line. Lines are skipped if they are still busy on a previous call.
Delayed Call Forward
Wait Time
Default value is
20 seconds
. In case this feature activated using * codes (*92 code), the
call will be forwarded after this preconfigured amount of time.
No Key Entry Timeout
Default is
4 seconds
. Dialing process is completed and outgoing call is initiated if no key
entry occurs during this preconfigured interval.
Early Dial
Default is
No
. Use only if proxy supports 484 response. This parameter controls whether
the phone will send an early INVITE each time a key is pressed when a user dials a
number. If set to “Yes”, an INVITE is sent using the dial-number collected thus far;
Otherwise, no INVITE is sent until the “(Re-)Dial” button is pressed or after about 5
seconds have elapsed if the user forgets to press the “Re-Dial” button.
The “Yes” option should be used ONLY if there is a SIP proxy configured and the proxy
server supports 484 Incomplete Address response. Otherwise, the call will likely be
rejected by the proxy (with a 404 Not Found error).
This feature does NOT work with and should NOT be enabled for direct IP-to-IP calling
.
Dial Plan Prefix
Sets the prefix added to each dialed number.
Use # as Dial Key
Default is
Yes.
It allows users to configure the “#” key as the “Send” (or “Dial”) key. If set
to “Yes”, “#” will send the number. In this case, this key is essentially equivalent to the
“Dial” key. If set to “No”, this “#” key can be included as part of number.
