WellGate 3232s is a 32-port FXS gateway with SIP protocol IP device which connects 32 Lines
of analog telephone sets or connect to analog CO line of legend PBX to make or receive VoIP
call over Internet or VPN network. This device is suitable for office IP-PBX application between
office to office or office to branch office to call via PSTN Line and IP network.

To select up to 16 SIP service Accounts

WellGate 3232S is appropriate to use to 16 VoIP Service Providers, IP Centrex service
or IP-PBX within offices and remote branch offices. One of 16 SIP Servers ( or ITSP
Service provider or alternative IP-PBX ) can be assigned to WellGate 3232s to make or
receive IP Call. It provides up to 16 SIP Trunk numbers for this gateway to use.

Flexible Dial plan and Route Plan Features

WellGate 3232s 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 want this call to
go out or allow to income. For instance, IP incoming call may reach to one FXS port with
Priority or Cyclic access. You can also configure IP incoming call byMatched prefix digits,
matched dialing number to FXS line and Matched digit length. From FXS outgoing call to
SIP IP routes, the hunting type supports Priority or Cyclic or simultaneously 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.

Suit to IP-PBX IP calls

WellGate 3232s is a SIP IP device to connect with analog telephone set and register to
IP-PBX (or SIP Server IP Telephony platform) to make or receive IP call without affecting
existing cabling, extension number or dial behaviors. It is an easy and quick way to
upgrade from existing PBX to VoIP calls by using existing cable layout and dial number plan.
