Class 4 in traditional telco was all about carrying your traffic over 
long distance, hence it was called tandem, they were used to 
interconnect trunks, class 5, well was for termination of calls locally, 
usually a class for would handoff to a class 5, or class 4 would be 
built into class 5.

If you relate that to voip, ur class 4 will be the gateways, which 
interconnect traffic and do little else, except route high volumes, and 
your class 5 will really be the pstn to IP conversion endpoint.

But in IP these boundaries are getting muddier, because with more and 
more smaller endpoints who needs to worry about the trunking parts, so 
alot of the features of class 4 are being dumped into class 5,

I would decide what you need it 4, and see if it does it, rather than 
using terms like class4 class4, its like using layer2, layer3 swicthes, 
some logic but really just marketing.

PS Telecoms and me arent the best of friends, so the above might be a 
oversimplification
