WellGate 2808 is 8-port FXS gateway with SIP protocol IP device
which connects up to 8 Lines of analog telephone set (or, analog
trunk line of legend PABX) to make or receive VoIP call over Internet
or VPN network. This device is not only suitable for legend PABX to
enable VoIP call without changing existing cabling, dial plan, and
extension number, but also work with IP-PBX and SIP Server directly.
Its design, firmware, auto provision and webpage are consistent
with WellGate 2504 (4 ports FXS) and WellGate 2424S (24 ports FXS)

To select up to 16 SIP TRUNK Accounts

WellGate 2808 is appropriate to use 16 VoIP SIP Trunk or IP Centrex service or IP-PBX
within offices and remote branch ffices. One of 16 SIP Servers (or ITSP Service provider
or alternative IP-PBX ) can be configured freely at each line (FXS port ) to make or receive
IP Call. It provides 16 service platforms according to your dial number or routes plan.

IPv6 VoIP Gateway is ready to Market

IPv6 address was developed for years, however, it was not practical to our life up to now.
More and more electronic devices are able to link to IP Network(for instance, Internet of
Things, IoT). This makes existing IPv4 address supply in short to global market. Meanwhile,
the emerging countries are not able to increase IPv4 address supply due to strong market
demand on broadband services. WellGate 2808 is an SIP based FXS gateway which was
built-in both IPv6 and IPv4 IP address. Whenever you are ready to deploy IPv6 network,
or reserve the future expansion to IPv6 from existing IPv4 address, WellGate 2808 is ready
to grow up with you. Both IPv6 and IPv4 addresses are working simultaneously at Voice IP
Call. Its flexibility of both IPv6 and IPv4 accept and interwork both addresses on today and
tomorrow whenever you need.

Flexible Dial plan and Route Plan Features

WellGate 2808 provides flexible Dial Plan between FXS and SIP IP Trunk (SIP Soft Switch
or IP-PBX). Dial Plan is to configure in what condition the digits can be sent out to/from IP
network. The dialing inter-digit time before dialing is configurable to meet local PSTN line
or PBX’s extension line. Dial Rule is able to detect the prefix code and maximum digits
reached and then dial automatically. The Digit Manipulation (DM) allows you to configure
matched prefix code, digits length, start and stop digit position to be replaced digits as well.

Route Plan is to configure the incoming and outgoing call routes which you wanth you want
this call to go out or allow to income. For instance, IP incoming call may reach to one FXS
FXS port with Priority or Cyclic access. You can also configure IP incoming call by Matched
prefix digits, matched dialing number to FXS line and Matched digit length. From FXS outgoing
all to SIP IP routes, the hunting type supports Priority or Cyclic or Simultaneously to select
which SIP trunk ( SIP Proxy Server, or IP-PBX ) to go. FXS outgoing call routes also support
by Matched prefix digits, Matched outgoing SIP Trunk number and Matched digit length. Both
directions support No Answer time out and Backup Routes.

Upgrade existing PABX to enable VoIP call

WellGate 2808 is a SIP IP device to connect with existing PABX and enable to make or receive
VoIP call without affecting existing cabling, extension number or dial behaviors. It is an easy
and quick way to upgrade existing PABX to VoIP calls. No need to expand your PABX’s extension
olines and analog trunk lines.
