TOPEX BYTTON HSDPA
User’s Manual
The voice state shows “stopped” when the voice connection is temporary
unavailable (lack of signal, no registration, other reasons). In this case,
you will hear in your headset a busy tone, indicating that you cannot make
voice calls!
The “stopped” problem may be temporary. For example, the SIM may not be properly registered, the RF
signal is weak or the network is busy.
Try to call again later or reset the Bytton equipment to re-activate the voice connection.
5.8.3. VOICE Settings
Here are the settings for the analog phone interface (FXS or FXS) of the equipment.
Call Priority
:
Establishes which kind of call has higher priority, Data or Voice.
The default is “Don’t care”. This setting is important for 2G networks (such as
GSM, GPRS, EDGE) where you can’t have voice and data connection
at the
same time
. Then you must set a priority.
If you set the call priority to
Voice
, then when you try to make a voce call, Bytton will stop the ongoing
data connection to allow you make the call.
If you set the priority to
Data
, the data traffic will interrupt an voice call already established.
Note
:
In case of 3G networks (UMTS, HSDPA) that support simultaneous voice and data calls there is
no need to impose a priority, so you should leave the setting on the default value “Don’t care”
Port type
: first of all, you must choose the type of the phone port to use. You can select either FXS (for
connection to a trunk of the PBX or directly to an analog phone) or FXO (when BYTTON HSDPA may be
connected to a local extension of the PBX, as you would connect a standard office phone). The default
is FXS.
Ring type
: select the type of ring signal. The default value “0” means a standard ring current, frequency
25 Hz, symmetrical (with no DC component). The value “1” selects a ring current with DC component,
thus asymmetrical. This vas requested for certain types of phones, which won’t ring properly with a
symmetrical ring current.
Target Number -
specifies how the incoming calls should be treated, in case of phone interface
configured as FXO.
The default is off, or you should type a phone number (up to 4 digits).
When a call comes in through the FXO interface, you have two options: either provide the caller with DISA
tone, allowing him to dial numbers in DTMF mode, or specify a Target number. In the latter case the DISA
feature is not used, instead the incoming call is routed directly to the local extension established in the
Target Number field. For instance, this extension may be the attendant console, so the operator will route
the calls manually.
Extension number
– the number of the local extension where the Bytton equipment is connected, in case
of configuration as FXO,.
Debug messages:
establishes the type of debug messages that will be sent to the Log file.
Valid values are from 000 (the default, no messages are sent) to 111 (full debug, all messages will be
sent). These messages are useful for troubleshooting. There is no need of them for making voice calls.
In the paragraph 5.5.2, about the “System Log”, you can see the influence of selecting a value of 111 for
the debug messages, as opposed to the default 000.
