interface. In order to access the web user interface, you need to know the IP address of
your new phone. To obtain the IP address, press the OK key on the phone. Enter the IP
address (e.g., http://192.168.0.10 or 192.168.0.10) in the address bar of web browser on
your PC. The default administrator user name and password are both “admin”

Dial plan is a string of characters that governs the way your SIP-T23P/T23G IP phone
processes the inputs received from your phone keypad. The SIP-T23P/T23G IP phone
supports the following dial plan features:
Replace Rule
Dial-now
Area Code
Block Out
The basic expression syntax you need to know:
62
Customizing Your Phone
$
The “$” should be followed by the sequence number of a parenthesis. The
“$” plus the sequence number means the whole character or characters
placed in the parenthesis. The number directs to the right parenthesis when
there are more than one. Example:
A replace rule configuration, Prefix: "001(xxx)45(xx)", Replace: "9001$145$2".
When you dial out "0012354599" on your phone, the IP phone will replace the
number with "90012354599". “$1” means 3 digits in the first parenthesis, that
is, “235”. “$2” means 2 digits in the second parenthesis, that is, “99”.
You can configure one or more replace rules (up to 100) to remove the specified string
and replace it with another string. You can configure a pattern with wildcards (refer to
the expression syntax in the table above), so that any string that matches the pattern
will be replaced. This feature is convenient for you to dial out a long number. For
example, a replace rule is configured as “Prefix: 1” and “Replace: 1234”. When trying to
dial out the number “1234”, you just need to enter “1” on the phone and then press the
Send soft key.
To add a replace rule via web user interface:
