WellGate 2522 is an 2-Line FXO plus 2-Line FXS gateway with SIP protocol IP device which
allows to connect 2 Lines of analog PSTN telephone line and connect to 2 Lines analog
telephone set (for instance, analog trunk line of PABX) to make or receive VoIP call over Internet
or VPN network. This device is suitable for office PABX to enable VoIP call without changing
cabling, dial plan, extension number.

To select up to 4 SIP TRUNK Accounts

WellGate 2522 is appropriate to use four VoIP SIP Trunk or IP Centrex service or IP-PBX within offices and remote branch

able to link to IP Network, 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 2522 is an

SIP based FXO plus FXS gateway which was built-in both IPv6 and IPv4 IP address. No matter when you are ready to deploy

IPv6 network now, or reserve the future expansion to IPv6 from existing IPv4 address, WellGate 2522 is ready to grow up with

you. Both IPv6 and IPv4 address 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 Featur es

WellGate 2522 provides flexible Dial Plan between FXO, FXS and IP Trunk (SIP Soft Switch). Dial Plan is to configure in

Route Plan is to configure the incoming and outgoing call routes which you desired this call to go out or allow to income. For

instance, IP incoming call may Reach to one FXO or FXS port with Priority or Cyclic access. You can also configure IP

incoming call by Matched prefix digits, Matched dialing number to FXO/FXS line and Matched digit length. For FXO/FXS

outgoing call to IP routes, the hunting type supports Priority or Cyclic or Simultaneously to select which SIP trunk ( SIP Proxy

Server ) to go. FXO/FXS outgoing call routes also support by Matched prefix digits, Matched outgoing SIP Trunk number and

Matched digit length. Both direction supports No Answer time out and Backup Routes.

Upgrade existing PABX to enable VoIP call

WellGate 2522 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. Do

not expand your PABX’s extension lines and analog trunk lines. Bypass PSTN line to PABX automatically if this device power
