IP Phone Release Notes 2.4
Dial Plan Length Extended
In Release 2.4, the dial plan length has been extended to accept up to 512 characters. Previously,
this field could only accept up to 128 characters.
If a User enters a dial plan longer than 512 characters, or a parsing error occurs, the phone uses
the default dial plan of “x+#|xx+*”.
Limitations
The following are limitations of the extended field dial plan:
• If the User enters a dial plan longer then 512 characters, the phone uses the default dial plan
instead. If this is the case, the Administrator cannot change the dial plan from the
configuration files. The dial plan must be changed from the Aastra Web UI.
Emergency Dial Plan Supports Pattern Matching
The IP Phones now support emergency dialing using pattern matching and prepend dial plan
functionality.
There are two ways to dial a number on the phone:
• dialing digit-by-digit (i.e., select line and dial)
• dialing by string (i.e., pre-dial then go off-hook)
When a user dials digit-by-digit, the phone adds every digit to a dialed string and checks against
the dial plan. If the phone is not locked, it checks against the regular dial plan. If the phone is
locked, it checks against the emergency dial plan.
When a user dials by string, (pre-dial, speed-dial, etc., and then goes off-hook), and the phone is
not locked, it checks to see if the number matches the registered emergency dial plan. If it
doesn’t match, it blocks the call from going through. If the phone is locked, and the number
matches the emergency dial plan it allows the call to go through.
Adding a prepend to a dial plan also works with both dialing digit-by-digit and dialing by string.
Limitation
The following is a limitation for emergency dial plans with pattern matching:
• Secondary dial tone is not supported.
