How about a beroNet gateway?

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