Some time ago (~2007) I used a Vega unit to connect to a Telco PRI, a PRI
file transfer unit (predates broadband and FTP) and a PRI connection on a
PaBX, a total of 3 PRI connections.

The (very basic) dialplan sent 6 DDI numbers to the ISDN file transfer box,
and the rest to the PaBX, it had the capability (with an extra licence) to
also add IP destinations to the dialplan, but this was of no use to us.

I found the UK support to be very good.

Cheers
