Reset to factory defaults
The unit can be restored to factory defaults by pressing an internal reset button on the PCB.
This can be used to recover a phone where the user name or password have been lost. See
section 10.
Relay operation from DTMF tones
For door opening purposes, output relays can now be triggered by the receipt of a
programmable DTMF tone sequence. This means that a phone's relays could potentially be
triggered from any phone on the system. See section 5.11.1.
Default autoanswer mode
The unit can now be set to automatically answer an incoming call, with a choice of 3 different
autoanswer modes to suit applications such as paging and intercom. See section 5.5.
2.2 New in Version 2
Version 2 firmware added the following features from version 1:
Multiple SIP proxies
The unit can now hold up to 4 alternate addresses for the SIP proxy and registrar with a
prioritised failover sequence between them. This means that if it fails to register with the first
server it will attempt to do so with the next and so on.
The unit can be set to automatically refresh its registration at a predetermined interval to
ensure that registration is maintained at all times (or if not raise an alarm).
This provides a high degree of resilience across the network and reduces the possibility of a
single point of failure jeopardising the operation of the whole system.
Additional functions for Relay outputs and LEDs
In addition to the functions in version 1, the unit can now trigger its output relays and / or
LEDs on:
• PAGE (activated by PAGEMODE, see section 5.5). For example a relay could be used to
activate a public address amplifier, allowing the unit to be used as a mini PA.
• EMERGENCY (if an outgoing call is designated as an emergency call), where for
example a relay could be used to activate an emergency beacon, and
• REGISTERED, where for example an LED could indicate that the unit is available for use
(i.e. it can make a call).
Additional LED drive
Version 2 allows 3 programmable LEDs instead of 2. Note that the number of LEDs fitted
varies with model type. Some standard models have no LEDs fitted.
Page Mode
Auto-answer mode 3 is now explicitly referred to as PAGE MODE to highlight its potential use
as a PA or paging system. Functionally it is unchanged, except for the LED and relay triggers
described above.
3. How the product is intended to work
The VoIP telephone has been designed to mimic the behaviour of a traditional, analogue
telephone, specifically based on the GAI-Tronics range of rugged telephones, to give
continuity where VoIP and analogue units are used in similar situations.
Accordingly, traditional telephone terminology is used throughout the manuals and
documentation, and many of the features are designed to mimic analogue telephone
behaviour.
A major difference between analogue telephones and VoIP is that, with analogue units, most
signalling and tones such as ringing, dial tone, busy tone etc., are provided by a telephone
exchange (PABX), whereas the VoIP unit must generate these itself. The telephone provides
features to change the various tones to emulate those of different countries or PABXs, to give
familiar operation in its intended location.
