We have a similar situation but have needed to run a legacy Telrad PBX 
in parallel with a test Asterisk VOIP PBX.

The way we have got round it is to run a minimal configuration of 
Asterisk in combination with a multi-interface Digium PRI card on a 1U 
short depth Supermicro server. The OS is a minimal CentOS installation.

Effectively we have a PRI to IAX2 to PRI gateway which has operated 
flawlessly for 18 months. In the same time we have 3-4 test VOIP PBX 
systems and the Telrad is still non-the-wiser that it isn't still 
talking directly to the Telco.

I bet this would be cheaper, easier to configure and more flexible that 
a proprietary PRI to SIP Gateway. You also get the advantage of IAX2 
trunking rather than SIP.
