ISDN VoIP Gateway - Use your existing ISDN phone system with VoIP lines
You can take advantage of VoIP lines if your current phone system doesn't support VoIP/SIP by using an ISDN VoIP gateway (ISDN to SIP converter).
We will configure the ISDN VoIP Gateway with the details of your chosen SIP provider, you unplug from the ISDN and plug into the ISDN VoIP Gateway and start saving money straight away.
The ISDN VoIP Gateway connects to a PoE class 1 supply, if you don't have one we can supply them for £20
You will need to enable port forwarding in your firewall and lock the the ports to the VoIP exchange for security. In a Draytek 2860 or newer this is approximately 20 minuites, if you want us to do this for you we can but it will be chargeable at our normal support rates. In other routers it will take longer due to us being unfamiliar with the user interface
This ISDN VoIP Gateway has been added to a very small list of BT approved devices to use their SIP services, and is by far the easiest to implement as well as the cheapest ISDN VoIP Gateway on the market.
