[Serusers] Asterisk/Digium as PSTN gateway and SER as backend soft switch?

[Tom]

  I don't think SER and SEMS supports any directly attached PRI cards.  It
is a SIP Proxy registrar, designed to deal with gateways (and Asterisk
could be a gateway).

  However, I don't think that Asterisk makes a very cheap gateway.  Once
you factor in the cost of the card, the G.729 codec license, and a fast
enough computer to do the coding (since the T1 card does not contain any
DSPs), it doesn't seem so cheap anymore.  And you'll end up with a gateway
which doesn't support VAD/CNG or G.723 either.  A used Cisco 2621 with a
HDV card starts to look good.  You get dedicated DSPs for coding, and
support for a variety of different CODECs.  Plus working VAD/CNG.
