I was looking at moving our office to an Asterisk implementation and
was checking out the cost of the FXO/FXS hardware. I've been looking
at Digium's hardware, but was wondering if this was the best route to
take.

Any suggestions?

We have six analog phone lines coming in and 8 analog phones connected
to our current system. The current software isn't great and we can't
use SIP based phones with it so I'd like to move to something that
would support more soft phone clients.

Thanks.
