The last time I tried using spa3000's for PSTN connections,  I had a lot of 
difficulty tuning the settings to get rid of some echo the users were 
hearing.   I don't know what the local loop length was, and the wiring in 
that neighbourhood is pretty old - both probably had a strong influence on 
what I was seeing.  My determination at that time (~3 years ago) was that 
they were good for home connections, but not suitable for business use.   I 
ultimately went with a Sangoma card (A200 +HWEC module), it killed the echo 
and sounded great.

YMMV - Firmware and hardware has probably changed quite a bit in 3 years, 
and your loop characteristics might be better.   My inclination would be to 
buy one, and see how well it works at your site.

Depending on how you want your system to work - auto-attendant is a good way 
to go if you won't have DIDs for all or most individuals.  Our 
receptionist's (and our client's) time was being chewed up by all calls 
being forced to go through her before we implemented an auto-attendant.
