can be used as a record output by using the webserver interface. The
output is then a sum of the caller and main audio input so both sides of the
conversation can be recorded from this output.

GSM Antenna
This is an SMA bulkhead connection to connect to an antenna to
communicate with the GSM base station. We provide a simple ‘stubby’
antenna that is suitable for most applications, but where the signal is poor
or the install is in a sensitive area, you should use hi gain antennas and/or
low loss extension cables.
SIM Card Slot
This is a standard SIM card slot (also known as mini SIM or 2FF).
RS232 Serial Port
The serial port allows direct connection to a 9 way ‘D’ type connector on a
PC via a pin to pin cable. See chapter 5 for details about this interface.

Ethernet Port
This is an RJ45 port which should be connected via CAT5 cable to an
Ethernet device or switch. The port will automatically set the pins to suit
(Auto-MDX) and select the maximum available speed (10Mbps or 100Mbps)
depending on the connected infrastructure (Auto-Negotiation).
