4.3 Dial Process
The Ericsson W25 supports E.164 numbering. There are three ways to
indicate that the dialed number sequence is complete:
• Dialing the EON key (e.g. # or *) immediately sends the call.
• An Inter Digit Timer (IDT) is used to check the dialing process.
• A specified number of digits must be dialed before the call is
placed.
The EON key is configurable as well as the IDT.
4.3.1 Dialed Number Modification
It is possible to do number modifications, e.g. remove and/or add digits to a
dialed number.
The dial plan consists of a pattern string to match dialed digits, and the
ability to strip, append prefix digits, and/or append suffix digits.
4.3.2 Local Call Prefix
A local prefix can automatically be added to a dialed local number. This is
useful in places where the PSTN does not require the local prefix in local
calls.
4.3.3 Fixed Number Dialing
Fixed Number Dialing is supported when a SIM providing this service is
installed. When enabled, only calls to fixed numbers stored on the SIM are
allowed.
4.3.4 Fax Dialing
A local fax call is detected through a unique prefix before the phone
number. The fax prefix is configurable and is removed before the T.38 call
is setup.
4.3.5 Supplementary Services
The UMTS/GMS supplementary service codes (i.e. #67# etc) is possible to
configure with a service code of choice, in order to have the same service
codes as in a fixed network.
