There's no one-step solution I'm aware of. Cisco sells something
called an AS5300 that supposedly can terminate a DS3 and convert it
all to SIP. Otherwise, you need a channel bank like the Adtran MX2800
to break the DS3 into 28 T1s, which you can then terminate in your
preferred manner, either into appliances or actual PC hardware with
Digium cards.
