asterisk users - Nov 2007 - Can I connect device on FXS of Sipura 3000 to internet virtually ? - it can only call ISPs numbers on POTS line

Hi,

I have an older phone with touch screen from Philips. It have ti connected 
to Sipura 3000 FXS port and majority of features work ok.

But phone also has touchscreen and web browser that I'd love to use for 
accessing my local web pages. But the phone only allows me to setup ISP 
phone number and it wants to call it to get to Internet. Since it is 
connected to Sipura3000, call can come to Asterisk and I'd love to somehow 
fool that device and connect it to local web pages ? I guess I could somehow 
mimic ISP "internet calling" feature on local Asterisk server, but
have no
clue even where to start searching ...

Any advice ?

Thanks in advance,

regards,

Rob.
