I'm currently looking to interconnect my Asterisk PBX system with the PSTN
via a digital PRI/T1.
I know a multitude of options exist for internal PCI cards
(Digium/Sangoma/Rhino), I was wondering if anyone has any experience or
recommendations of external PRI media gateways that support SIP.
So far I've found:
VegaStream Vega 400
Audiocodes Mediant 2000
MediaTrix 1531
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.
