Disable Reminder Ring
for On-Hold Call
Default is No. Do not play the reminder ring when this is set to Yes.
Disable Visual MWI If set to “Yes”, the MWI information will not be transferred to the analog phone
connected to the FXS port.
Ring Timeout
Incoming call will stop ringing when not picked up given a specific period of time.
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
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.
Dial Plan Dial Plan Rules:
1. Accept Digits: 1,2,3,4,5,6,7,8,9,0 , *, #, A,a,B,b,C,c,D,d
2. Grammar: x - any digit from 0-9;
• xx+ - at least 2 digits number;
• xx. – at least 2 digit number.
• ^ - exclude;
• [3-5] - any digit of 3, 4, or 5;
• [147] - any digit 1, 4, or 7;
• <2=011> - replace digit 2 with 011 when dialing
• < =1> - add a leading 1 to all numbers dialed, vice versa will remove
a 1 from the number dialed
• | - or
• Example 1: {[369]11 | 1617xxxxxxx} – Allow 311, 611, 911, and any 11 digit
numbers with leading digits 1617
Example 2: {^1900x+ | <=1617>xxxxxxx} – Block any number of leading digits
1900 and add prefix 1617 for any dialed 7 digit numbers
• Example 3: {1xxx[2-9]xxxxxx | <2=011>x+} –Allow any combinations of numbers
with 11 digits which has a leading digit 1, but 5th digit cannot be 0 or 1. Or any length

3. Default: Outgoing - {x+}
Example of a simple dial plan used in a Home/Office in the US:
{ ^1900x. | <=1617>[2-9]xxxxxx | 1[2-9]xx[2-9]xxxxxx | 011[2-9]x. | [3469]11 }
Explanation of example rule (reading from left to right):
• ^1900x. - prevents dialing any number started with 1900
• <=1617>[2-9]xxxxxx - allows dialing to local area code (617) numbers by dialing
7 numbers and 1617 area code will be added automatically
• 1[2-9]xx[2-9]xxxxxx |- allows dialing to any US/Canada Number with 11 digits
