I've used Nokia 32 with a TDM400 FXO. It works reasonably well but has 
some anoying "features", like taking 5-10 seconds to establish a call, 
hangup detection problems, cdr records always being answered, etc, etc. 
It's doable but not perfect.

I haven't tried ISDN GSM Terminals but do have fixed-land ISDN. ISDN is 
so much more reliable (faster setup, proper cdr and billing seconds, 
better voice quality) that I would consider a ISDN GSM terminal. Try 
searching google for quasar smartcell.

A Voip-GSM terminal sounds even better. No need for FXO, ISDN, etc. And 
you could manage it remotly. The Ateus Voice Blue looks good but I 
haven't had a change to try it out. Google around.. you find nice stuff 
like: http://www.thehightechstore.com/cellinterface.html

Let me know about your experiences.
