Dial Plan
Dial plan is a string of characters that governs the way how IP phones processes the inputs received from
the IP phone’s keypads. You can use regular expression to define dial plan.
Yealink IP phones support two mechanisms to help creat a dial plan:
Dial plan defined by four patterns (old dial plan mechanism): replace rule, dial now, area code and
block out, and each dial plan needs its own matched rule.
Dial plan defined by digit map (new dial plan mechanism): supports one or more matched rules in
one digit map string. It is helpful for completing multiple dial plan features: replace, dial now, block
out, and so on by one matching string.
If you enable new dial plan mechanism, old dial plan will be ignored.

Yealink IP phones support four patterns:
Replace rule: is an alternative string that replaces the numbers entered by the user. Yealink IP
phones support up to 100 replace rules.
Dial now: is a string used to match numbers entered by the user. When entered numbers match the
predefined dial now rule, the IP phone will automatically dial out the numbers without pressing the
send key. Yealink IP phones support up to 100 dial now rules.
Area code: are also known as Numbering Plan Areas (NPAs). They usually indicate geographical
areas in one country. When entered numbers match the predefined area code rule, the IP phone will
automatically add the area code before the numbers when dialing out them. Yealink IP phones only
support one area code rule.
Block out: prevents users from dialing out specific numbers. When entered numbers match the
predefined block out rule, the LCD screen prompts “Forbidden Number”. Yealink IP phones support
up to 10 block out rules.
You can configure these four patterns via web user interface or auto provisioning. For replace rule and
dial now, you can select to add the rule one by one or using the template file to add multiple rules at a
time.
