Concept: an IP PBX, SIP server or operator network connects over Ethernet using SIP, optionally through an IPSec, L2TP or PPTP VPN, to the Telematics FXS gateway, which provides 4 to 32 RJ11 analog lines for desk and cordless phones and fax machines, and shares the broadband with PCs on its LAN ports.

Keep the phones. Move the lines to IP.

Analog phones, cordless handsets and fax machines still work well and cost little. The FXS gateway gives each of them a SIP line, so they join your IP PBX or operator voice service without being replaced.

Reuse

Your analog phones

Plug existing desk phones, cordless phones and fax machines into the RJ11 ports. No IP phones to buy.

Compatible

IP PBX and SIP servers

Standard SIP, compliant with the TISPAN / IMS standard. Also supports NGN and H.248 voice services.

All-in-one

Router, VPN and firewall

Routing, NAT, DHCP, QoS, VPN and firewall in the same box. Runs as a gateway, router or bridge.

Manageable

Local and remote control

Web, HTTPS and SSH management on site; TR-069, SNMP and syslog for large deployments.

How it works

Each FXS port acts as a SIP extension on the network side and as an ordinary telephone line on the phone side. The gateway converts the call in both directions.

Connect to the network

Plug the WAN/LAN1 port into the office LAN or broadband. Use static IP, DHCP or PPPoE.

Register the lines

Plug in the phones

Connect analog phones and fax machines to the RJ11 ports. They get dial tone, ringing and caller ID.

The other LAN ports share the same connection with PCs, through the gateway's router, firewall and QoS.

Choose by the number of phones

One FXS port serves one analog phone or fax machine. Pick the model that matches the number of lines at your site.
