Hi, Digium have Wildcard for FXO/FXS connections (i.e., telephone lines) and E1/T1 cards such as the TE110p. There're a few things you might want to consider:
1) TE110p is much more expensive 2) it is too much for a "small shop". Concurrently supports upto 15 incoming and 15 outgoing calls (or 30 incoming calls). Hence, the number of clients can be up to 100, depending on your service needs and configuration. 3) you do need echo cancellation or your VoIP phone users will suffer. The lastest Digium E1 card support hardware echo cancellation. The builtin software echo cancellation is quite incapable! Hope that helps! H.
