FBF WLAN 7050 als ISDN PPP Server und ISDN->WAP Gateway

[pawbrok]

First off all, sorry for English.

I have Swissvoice/ascom Eurit 4000 connected to FBF WLAN 7050 S0 Bus.
The phone has a build-in WAP Browser. It needs a PPP via ISDN Internet connection for WAP Browsing. It also needs an ISDN->WAP Gateway.

But I want to use the existing Internet connection (via DSL or Ethernet in ATA Mod).

1. Could we set the PPP Server, wich can give the Internet to S0 Bus (for Eurit 4000 or another ISDN data terminal)?
2. Is it possible to build in FBF 7050 an ISDN->WAP Gateway (Kannel - Open Source SMS and WAP Gateway or similar) ?

Thanks for any idea

Greetings
