6.2.8 Hook Flash Time
This setting controls the “Hook Flash” feature which on most modern
phones is implemented as a button that simulates a quick off-hook/on-
hook/off-hook cycle. This is the same function as quickly tapping at the
hook on an old style phone, also called Register Recall (the R-button).
The setting specifies the time-window in which the on-hook condition exists
in order to be interpreted as a hook flash.
6.2.9 CLIP
The Ericsson W35 supports CLIP (Calling Line Identification Presentation)
service in both on-hook and off-hook states using the DTMF and FSK
protocols, supporting both ETSI and Bellcore standards.
It is possible to configure a country specific profile for the CLIP service and
also define how to present the incoming numbers in the desired format.
6.2.10 On Hold Ring
This setting specifies what will happen if the user goes on-hook with an
active call placed on-hold. If enabled, the user will be notified about a
remaining on-hold call ring signal. If disabled, all calls will be disconnected
when going on-hook.
For each of the FxS ports (“Phone” and “Phone/Fax”), the receiving and
transmitting gain can be adjusted, with respect to the nominal relative level.
6.3 Dial Process
The Ericsson W35 supports E.164 numbering. E.164 numbers can have a
maximum of 15 digits and are usually written with a + prefix.
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.
6.3.1 Dial Plan
The dial plan consists of a number of rules, defined using regular
expressions (ref. POSIX 1003.2). These rules are used to match dialed
digits, and provide also the ability to strip/append prefix and suffix digits.
6.3.2 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.
