Actually, yes and no. The basic algorithms apply, but there is a great need to 
know what the kernel (realtime) thinks it needs to send out and what it 
receives. This close-knitting into kernelspace and correlation between input 
and output is not possible within asterisk, it should best be done in 
kernelspace.
