WellGate 2608 is an 8-Line FXS gateway with SIP protocol IP
device which allows to connect 8 sets of analog telephone to
make or receive VoIP call over Internet or VPN network
through Internet Telephony service provider. This device is
suitable for office user through ITSP service provider to
install at office or branch office to call between different
offices. It also can install at trunk line in front of digital PBX
to migrate digital PBX to IP Telephony call without changing
PBX’s dial rule and cable.

Rich Telephony Features

WellGate 2608 has 8-Line FXS ports. Each Line can be configured to meet different
countries Telephony requirements. For Instance, AC Impedance, Ring Frequency, Ring
Voltage, Distinctive Ring, Ring Cadence, different Tone (Level, Frequency, Cadence),
Hook Flash detection time, DTMF/FSK Caller ID generation, Polarity Reversal Billing signal
and Generate Current Drop Time (Open Loop Disconnect). FXS interface has highly
compatibility with different countries Telephony interface, but also support existing digital
PBX analog interface. You don’t need to worry the interoperability with existing PBX or
Telco equipment.

Rich Digit Manipulation Features

Flexible digit manipulation processes Matched Prefix code, Minimum digit length, replace
digits at start and stop digit position. This digit manipulation feature applies to FXS phone
dial out or IP incoming call or pre-program up to 4 groups of digit manipulation processors.
Each group can define up to 50 indexes to meet your variety dial purpose.

Flexible Dial plan

WellGate 2608 provides flexible Dial Plan from FXS to IP Trunk (SIP Softswitch). Dial Plan
is to configure in what condition the digits can be sent out to IP network during dialing.
The dial inter digit time before dialing is configurable to meet busy users or home user.
Dial Rule is able to detect the prefix code and maximum digits reached and then dial

Call Routes Plan

Route Plan is to configure receiver IP address at peer to peer ( P2P ) mode when dialing
from FXS phone. When dialing prefix code and Minimum length was matched at this plan,
the IP address was sent to receiver site directly. Besides, there are four groups of digit
manipulation can be applied at Call Routes plan before sending as well. Each Routes plan
has an Backup Routes P2P IP address in case of original one was failure. Up to 50
entries of Call Routes List are supported to meet your application.

Suit to IP Telephony Service Provider

WellGate 2608 is a SIP IP device to connect with existing analog telephone set to make
IP call. Its Simple, Slim and Compact design and easy installation allow office users or
SOHO users to make or receive call just like an legend telephone call but less cost. It is
compatible with broadband internet service devices such as ADSL/Cable Modem and
WiMax/3G Modem. It helps ISP provider to provide Telephony service to existing
customers without additional cable.
