Also have a look at Patton SmartNode 4960 range.

They are available in various configurations/numbers of channels, some of 
which are upgradable to more channels at a later date:

We have the ISDN2 and Analogue versions of these gateways (same software) 
and so far they have been very reliable, and can be configured in a variety 
of fail-over situations in case asterisk or the connection to the server 
dies, incoming calls can be automatically routed either back out on another 
ISDN channel or out to another SIP/analogue gateway etc.
