<p>A better choice would be to get a T1-E1 interface card over USB. What if we can use the GPIO pins?</p>

How about a beroNet gateway?<br>

You did not mention if the office uses BRI or PRI lines. There used to<br>
be cheap USB HFC chipset based ISDN BRI (not PRI) Terminal Adapters<br>
(e.g. Billion tinyUSB ISDN TA 128k) but they don't seem available<br>
anymore. Afaik FreeSWITCH does not support them (a HFC BRI/PRI module<br>
would be cool) but they should work with the latest dahdi+zaphfc<br>
patch/libpri/asterisk or mISDN/lcr/asterisk. Thinking of it maybe you<br>
could make lcr talk to FreeSWITCH but I never investigated that.<br>
