I had a conversation about this with XO some years back and they said 
they were going to offer it.  I don't know if they do now.

However...why??  Why wouldn't you just buy this as SIP to begin with? 
If it's a matter of backup, just invest the money you'd waste on a PRI 
into a backup IP connection.
